The widespread use of WhatsApp as a communication tool makes it a candidate platform to facilitate the delivery of educational materials to radiology trainees in Eastern Africa. The aim of this pilot program is to assess the novel approach of using WhatsApp as a learning tool in pediatric radiology for residents in Kenya, Rwanda, Tanzania and Uganda. We recruited radiology residents to participate in a 3-month case-based pediatric radiology learning module that was delivered through WhatsApp to personal cell phones. Residents were presented with a multiple choice question once a week. Once they submitted their answer, the correct answer and explanations for each choice were provided. Questionnaires investigated comfort with reading pediatric radiology imaging, perception of the module content and convenience of the approach. Of the 72  participants, 40 (56%) responded to all 12 questions and both questionnaires, of whom 22 (55%) reported little to no comfort before the module and feeling very comfortable after. Confidence decreased with the number of incorrect answers. There was no correlation between the number of correct answers and the year level of the resident. Participants reported that the module was useful for learning pediatric radiology, found the material moderately difficult and found the application convenient for learning. Pediatric radiology educational content delivered over WhatsApp to residents in Eastern Africa is perceived as beneficial and convenient. This interactive learning platform provides opportunities for mentorship and enhanced learning of pediatric radiology., (© 2023.

Objective: The objective of our study is to explore Nepali women's beliefs about access to mammography screening, and motivations to get screened or not. This work was intended to be hypothesis generating for subsequent quantitative analysis and to inform policy and decision-making to improve access., Methods: We conducted structured qualitative interviews among nine Nepali women in the Northeast of the United States receiving care at a local community health center and among nine white women receiving mammography care at a large academic medical center in the Northeast. We analyzed the transcripts using a mixed deductive (content analysis) and inductive (grounded theory) approach. Deductive codes were generated from the Health Belief Model which states that a person's belief in the real threat of a disease with their belief in the effectiveness of the recommended health service or behavior or action will predict the likelihood the person will adopt the behavior. We compared and contrasted qualitative results from both groups., Results: We found that eligible Nepali women who had not received mammography screening had no knowledge of its availability and its importance. Primary care physicians emerged as a critical link in addressing this disparity: trust was found to be high among Nepali women with their established primary care provider., Conclusion: The findings of this study suggest that the role of primary care practitioners in conversations around the importance and eligibility for mammography screening is of critical importance, especially for underserved groups with limited health knowledge of screening opportunities and potential health benefits. Follow-up research should focus on primary care practices., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Commercially produced ultrasound coupling gel is often a scarce resource in rural regions of low-income countries that use sonography as their main imaging modality and, when available, may be cost prohibitive. Various homemade gels were created and tested to assure image quality was not compromised. Glucomannan-based gel and guar gum-based gel had superior physical properties in initial testing and showed no substantial difference compared with commercially available ultrasound gel on subject and phantom imaging and analysis (P > .05 using a 1-tailed sign test). Neither gel required heating, attracted insects, damaged ultrasound transducers, stained samples of clothing, or had harmful effects to subjects., (© 2018 by the American Institute of Ultrasound in Medicine.)

Radiology is undeniably male dominated. Alongside surgery and orthopedic surgery, academic radiology ranks near the bottom in having the lowest proportion of full-time female faculty members. Despite many efforts to recruit talented women, the pipeline entering the radiologic disciplines continues to flow at a trickle. One factor is the relative lack of role models for female medical students. Entrepreneurial women in radiology can lead the field with their innovation and creativity, courage, and commitment. In this article, the authors highlight two entrepreneurial female radiologists who shared their success stories at the American Association for Women Radiologists' session at the 2015 ACR annual meeting. Their successes underscore the potential for such women to serve as role models to female medical students and even college undergraduates. Despite the gender gap in radiology, the field has yielded some exceptional women who can take on challenges, overcome barriers and assume risks, create strategies and processes to operationalize their visions, secure funding, and expand their enterprises to make sustainable impacts both at home and abroad. As we move toward more patient- and family-centered care models and become increasingly visible to diverse populations, there is no better time for female leaders in radiology to inspire the next generation to join our essential and rewarding specialty., (Copyright © 2016 American College of Radiology.

The results of a survey sent to practice leaders in the ACR Practice of Radiology Environment Database show that the majority of responding groups will continue to hire recently trained residents and fellows even though they have been unable to take the final ABR diagnostic radiology certifying examination. However, a significant minority of private practice groups will not hire these individuals. The majority of private practices expect the timing change for the ABR certifying examinations to affect their groups' function. In contrast, the majority of academic medical school practices expect little or no impact. Residents and fellows should not expect work time off or protected time to study for the certifying examination or for their maintenance of certification examinations in the future., (Copyright © 2015 American College of Radiology.

Rationale and Objectives: A survey was administered to fourth-year radiology residents after receiving their results from the first American Board of Radiology (ABR) Core examination in 2013. The purpose was to gather information regarding resources and study strategies to share with program directors and future resident classes., Materials and Methods: An online survey was distributed to examinees nationwide. The survey included free-response and multiple choice questions that covered examination results, perceived value of enumerated study resources, case-based and didactic teaching conferences, board reviews, study materials for noninterpretive skills, multidisciplinary conference attendance, and free-form comments., Results: Two hundred sixty-six of 1186 residents who took the Core examination responded to the survey. Some resources demonstrated a significant difference in perceived value between residents who passed the examination and residents who failed, including internal board reviews (1.10, P < .01), daily didactic conferences (1.51, P < .01), and daily case conferences (1.43, P < .01). Residents who passed reported that conferences and review sessions at their institutions were modified with multiple choice questions, audience response, and integration of clinical physics and patient safety topics compared to residents who failed., Conclusions: Radiology residents and residency programs have adapted their preparations for the ABR Core examination in a variety of ways. Certain practices and study tools, including daily conferences and internal board reviews, had greater perceived value by residents who passed the examination than by residents who failed. This survey provides insights that can be used to assess and modify current preparation strategies for the ABR Core examination., (Copyright © 2015 AUR. Published by Elsevier Inc.

Background: In June of 2010, an antenatal ultrasound program was introduced to perform basic screening examinations at a health care clinic in rural Uganda. The impact of the program on the existing antenatal care infrastructure including the proportion and number of women receiving recommended antenatal care at clinic visits was unknown. The aim of this study was to investigate the relationship between the advent of the ultrasound program and the proportion of women receiving recommended antenatal interventions at their clinic visits. Change in the absolute numbers of antenatal services provided was also assessed., Methods: Records at the Nawanyago clinic were reviewed to determine the total numbers of women receiving specific interventions before and after the advent of the ultrasound program including HIV testing, intermittent preventive therapy for malaria, presumptive anti-parasitic treatment, and provision of iron and folate for anemia. The rate at which these interventions were provided (number of interventions per clinic visit) was also assessed. The differences in absolute numbers of antenatal interventions before and after the introduction of the ultrasound program were assessed using the Wilcoxon rank-sum test. Differences in intervention rate were assessed using negative binomial regression modeling., Results: The mean monthly numbers of women receiving each of these interventions increased significantly with the greatest increase seen in numbers of women receiving anemia and deworming treatments at +113% and +102% respectively (p < 0.001). The intervention rate increased for anemia treatment, deworming treatment, and 2nd dose of intermittent preventive therapy for malaria. A slight decrease in intervention rate was observed for 1st dose of malaria treatment with a rate ratio of 0.88 (0.79 - 0.98, 95% CI). Intervention rate for HIV testing was not significantly changed., Conclusion: The introduction of a low-cost antenatal ultrasound program at a health care clinic in rural Uganda was associated with increases in the number of women receiving specific recommended antenatal care interventions. Effect on intervention rates was mixed but showed an overall increase. The use of ultrasound in this context may provide a benefit to the maternal and neonatal health of the community.

Background: In June of 2010, an antenatal ultrasound program to perform basic screening for high-risk pregnancies was introduced at a community health care center in rural Uganda. Whether the addition of ultrasound scanning to antenatal visits at the health center would encourage or discourage potential patients was unknown. Our study sought to evaluate trends in the numbers of antenatal visits and deliveries at the clinic, pre- and post-introduction of antenatal ultrasound to determine what effect the presence of ultrasound at the clinic had on these metrics., Methods and Findings: Records at Nawanyago clinic were reviewed to obtain the number of antenatal visits and deliveries for the 42 months preceding the introduction of ultrasound and the 23 months following. The monthly mean deliveries and antenatal visits by category (first visit through fourth return visit) were compared pre- and post- ultrasound using a Kruskal-Wallis one-way ANOVA. Following the introduction of ultrasound, significant increases were seen in the number of mean monthly deliveries and antenatal visits. The mean number of monthly deliveries at the clinic increased by 17.0 (13.3-20.6, 95% CI) from a pre-ultrasound average of 28.4 to a post-ultrasound monthly average of 45.4. The number of deliveries at a comparison clinic remained flat over this same time period. The monthly mean number of antenatal visits increased by 97.4 (83.3-111.5, 95% CI) from a baseline monthly average of 133.5 to a post-ultrasound monthly mean of 231.0, with increases seen in all categories of antenatal visits., Conclusions: The availability of a low-cost antenatal ultrasound program may assist progress towards Millennium Development Goal 5 by encouraging women in a rural environment to come to a health care facility for skilled antenatal care and delivery assistance instead of utilizing more traditional methods.

Background: Trauma patients imaged at community hospitals often receive duplicate computed tomographic (CT) imaging after transfer to regional trauma centers (RTCs). CT scanning is expensive, is resource intensive, and has acknowledged radiation risk to the patient. The objective of this study was to review and evaluate the frequency, indications, impact on patient management, as well as associated radiation and charges for duplicate CT imaging of trauma patients transferred to our RTC from outside hospitals (OSH)., Methods: Patients transferred to our RTC between September 2009 and August 2010 were evaluated prospectively. The OSH patients' charts and provider interviews were used to determine the reasons for repeated scans. The primary outcome was frequency of duplicate CT scan, defined as a repeated CT image of the same body part within 24 hours. The reason for duplicate imaging and impact on patient management was categorized. Radiation exposure and charges for duplicate scans were also determined., Results: Of the 185 patients transferred to our facility, 177 were eligible. CT examinations at the OSH were performed on 137 patients (77%). A duplicate CT examination occurred in 38 patients (28%). The most common reason for duplicate CT scanning was lack of thin-section multiplanar data, on images sent via CD-ROM (37%). There was a change in management in 16 patients (42%). The patients with duplicate scanning received a median of 10.2 mSv (interquartile range, 6.6-15.7 mSv) of additional radiation, with a median charge of $409 (interquartile range, $307-$734)., Conclusion: More than one third of duplicated scans performed on transferred trauma patients were potentially avoidable, primary owing to inadequate transfer of data from the OSH CT scan. The capacity of a single CD-ROM is insufficient to contain full imaging data from a trauma scan, and establishing direct links to imaging data from OSHs would decrease the number of repeated CT scans performed on transferred trauma patients., Level of Evidence: Care management study, level III.

Historically, diagnostic radiology residents have been allowed time off from clinical duties to study for the ABR oral board examination. This practice has resulted in a disruptive "board frenzy" at many programs. The new ABR examination structure gives programs an opportunity to evaluate this practice. This position statement of the Association of Program Directors in Radiology describes the rationale behind a recommendation of no time off from clinical service before the ABR core examination., (Copyright © 2012 American College of Radiology.

The 2010 RAD-AID Conference on International Radiology for Developing Countries was a multidisciplinary meeting to discuss data, experiences, and models pertaining to radiology in the developing world, where widespread shortages of imaging services reduce health care quality. The theme of this year's conference was sustainability, with a focus on establishing and maintaining imaging services in resource-limited regions. Conference presenters and participants identified 4 important components of sustainability: (1) sustainable financing models for radiology development, (2) integration of radiology and public health, (3) sustainable clinical models and technology solutions for resource-limited regions, and (4) education and training of both developing and developed world health care personnel., (Copyright © 2011 American College of Radiology.

Changes to the ABR certification process are imminent, with a core examination after 36 months of training and a certifying examination 15 months after the completion of training replacing the current examination structure for residents entering training in July 2010 and beyond. The Residency Restructuring Committee of the Association of Program Directors in Radiology was developed to analyze the challenges and opportunities of these upcoming changes and provide recommendations to programs. The guidelines included in this article represent a summary of the work of this committee to date., (Copyright 2010 American College of Radiology. Published by Elsevier Inc. All rights reserved.)

Because the incidence of colonic diverticulosis is high in the general population, incidental asymptomatic diverticulosis is commonly seen on radiology imaging studies. However, diagnostic imaging performed specifically for diverticular disease is essentially limited to imaging of suspected acute colonic diverticulitis (ACD) and its complications. The clinical diagnosis of ACD can be challenging, and imaging has become an essential tool to aid in diagnosis, assess severity of disease, and aid in treatment planning. Computed tomography (CT) has replaced contrast enema as the imaging procedure of choice for diverticulitis. Ultrasound has also been successfully used for diagnosis, and magnetic resonance imaging (MRI) has significant potential as a radiation-free imaging test for acute colonic diverticulitis.

How intravascular helminth parasites evade host hemostatic defense mechanisms and survive within the circulating blood has not been adequately explained. Previous reports have described an inhibitor of the intrinsic clotting pathway in extracts of adult Schistosoma mansoni. Using a purified preparation of Hageman factor, we examined the ability of schistosome extracts and secretory products to inhibit the activation of human Hageman factor (factor XII) in an amidolytic assay. Both schistosome extracts and secretory products inhibited the activation of purified Hageman factor by more than 95%. Schistosome extracts inhibited activation of Hageman factor both by ellagic acid and by bovine sulfatides. In contrast, activated Hageman factor retained full activity in the presence of schistosome extracts as tested both on an amidolytic synthetic substrate and a natural substrate, plasma thromboplastin antecedent (factor XI). Our findings indicate that extracts and secretory products of adult Schistosoma mansoni contain a potent inhibitor of the activation of Hageman factor. Knowledge of a site at which schistosomes inhibit the intrinsic clotting pathway provides added insight into the mechanisms by which the parasites avoid the host hemostatic defense mechanisms.
