Of these, one resulted of high quality (mean score 86.5 %), another showed an average quality (mean score 61.8 %), and the remaining two proved to be of low quality (mean scores of 53.3 and 45.7, respectively). With the exception of the high-quality guideline, critical domains were Domain 2 "Stakeholder involvement" (total mean score 56.28 + 15.9), Domain 3 "Rigor of development" (total mean score 43.48 + 27.6), Domain 5 "Applicability" (total mean score 46.90 + 19.4) and Domain 6 "Editorial independence" (total mean score 50.55 + 35.7).

Purpose to assess the quality of guidelines on clinical indications for the use of 18F-FDG PET/CT in oncology using the AGREE II tool. Method from March to May 2019, the current literature was searched to identify guidelines focused on clinical indications for the use of18F-FDG PET/CT in oncology. The quality of the selected guidelines was then assessed by four independent appraisers using the AGREE II tool, which is organized in six quality domains accounting for a total of 23 items. The agreement among appraisers was measured using the intraclass correlation coefficient (ICC) analysis. Results four guidelines were selected. Of these, one resulted of high quality (mean score 86.5 %), another showed an average quality (mean score 61.8 %), and the remaining two proved to be of low quality (mean scores of 53.3 and 45.7, respectively). With the exception of the high-quality guideline, critical domains were Domain 2 “Stakeholder involvement” (total mean score 56.28 + 15.9), Domain 3 “Rigor of development” (total mean score 43.48 + 27.6), Domain 5 “Applicability” (total mean score 46.90 + 19.4) and Domain 6 “Editorial independence” (total mean score 50.55 + 35.7). ICC values ranged from 0.939 to 0.995, indicating very good agreement among the four appraisers. Conclusions a heterogeneous quality of guidelines dealing with clinical indications for the use of 18F-FDG PET/CT in oncology emerged from our analysis. Further efforts should be made to improve the reporting of the applied methodology as well as to promote the applicability of guidelines into clinical practice.

Objectives To prospectively determine the diagnostic accuracy of a biparametric 3T magnetic resonance imaging protocol (BP-MRI) for prostatic cancer detection, compared to a multiparametric MRI protocol (MP-MRI), in a biopsy naive patient population. Methods Eighty-two untreated patients (mean age 65 ± 7.6 years) with clinical suspicion of prostate cancer and/or altered prostate-specific antigen (PSA) levels underwent a MP-MRI, including T2-weighted imaging, diffusion-weighted imaging (with the correspondent apparent diffusion coefficient maps) and dynamic contrast enhanced sequence, followed by prostate biopsy. Two radiologists reviewed both the BP-MRI and the MP-MRI protocols to establish a radiological diagnosis. Receiver operating characteristics curves were obtained to determine the diagnostic performance of the two protocols. Results The mean PSA level was 8.8 ± 8.1 ng/ml. A total of 34 prostatic tumors were identified, with a Gleason score that ranged from 3 + 3 to 5 + 4. Of these 34 tumors, 29 were located within the peripheral zone and 5 in the transitional zone. BP-MRI and MP-MRI showed a similar performance in terms of overall diagnostic accuracy, with an area under the curve of 0.91 and 0.93, respectively (p = n.s.). Conclusions BP-MRI prostate protocol is feasible for prostatic cancer detection compared to a standard MP-MRI protocol, requiring a shorter acquisition and interpretation time, with comparable diagnostic accuracy to the conventional protocol, without the administration of gadolinium-based contrast agent.
