Introduction: Non-contrast computed tomography (CT) and CT angiography are the gold standard in neuroimaging diagnostics in the case of suspected stroke. CT perfusion (CTP) may play an important role in the diagnosis of stroke mimics (SM), but currently, it is not a standard part of the stroke diagnostic procedure. The project is a multicentre prospective observational clinical research focused on refining the diagnostics of stroke and stroke mimics (SM) in hospital care. Aim: This study aimed to evaluate the degree of specificity and sensitivity of multimodal CT (NCCT, CTA, and CTP) in the diagnosis of SM versus stroke. Methodology: In this study, we will include 3,000 patients consecutively admitted to the comprehensive stroke centres with a diagnosis of suspected stroke. On the basis of clinical parameters and the results of multimodal CT and magnetic resonance imaging (MRI), the diagnosis of stroke and SM will be established. To clarify the significance of the use of the multimodal CT scan, the analysis will include a comparison of the blinded results for each imaging scan performed by radiologists and AI technology and a comparison of the initial and final diagnosis of the enrolled patients. Based on our results, we will compare the economic indicators and costs that would be saved by not providing inadequate treatment to patients with SM. Conclusion: The expected outcome is to present an optimised diagnostic procedure that results in a faster and more accurate diagnosis, thereby eliminating the risk of inadequate treatment in patients with SM.

Aim: The aim of this study is to asses the suitability of three different ways how to quantify systemic sclerosis associated interstitial lung disease (SSc-ILD). Methods: In a group of 23 patients who met classification criteria for systemic sclerosis (SSc) the extent of pulmonary interstitial involvement in HRCT of the chest was evaluated by three different approaches. The essential method is a modified methodology according to Gay-Dutka/Vašáková, further we worked with its two simplifications. The first is the quantification of SSc-ILD in percent in a few cross-sectional levels the second is the determination of the percentage of changes in the most affected level. The results were compared with the development of selected indicators of pulmonary functional tests over the time. Results: There was not found statistically significant relationship between SSc-ILD quantification procedures and pulmonary function development over the time (p = 0.07), Nevertheless in subanalysis was found a trend towards relationship between lung function evolvement and percentage of changes in more levels or eventually Gay-Dutka/Vašáková method. Both methods have relatively high sensitivity towards the prediction of lung tets worsening. 85.7% is senzitivity of change percetage in more levels. Conclusion: Even though the results are not statistically significant, as the most suitable approach for quantification of SSc-ILD seems to be the percentual expression in more levels that is because of the trend that was found. Gathering of data continues and in a larger group of subjects the relationship can be statistically significant. [ABSTRACT FROM AUTHOR]

Transient perivascular inflammation of the carotid artery (TIPIC syndrome) formerly known as idiopathic carotidynia or Fay syndrome is relatively rare and not very well known entity of an unclear etiology with a typical clinical course and typical findings on imaging methods. In this communiction we present a case of 30 year old woman who presented with an unilateral painful swelling on the neck. Computed tomography was perf-ormed to exclude a neck abscess. CT and following ultrasound examination showed a thickening of the common carotid wall and an edema of the periarterial tissue in the carotic space. [ABSTRACT FROM AUTHOR]

Chronic obstructive pulmonary disease have varied clinical and radiological manifestations. Nowadays are patients with chronic obstructive pulmonary disease divided into specific groups - phenotypes. The treatment is specific according to these phenotypes. High resolution computed tomography is necessary in identification of each phenotype. The most patients with chronic obstructive pulmonary disease have pulmonary emphysema which is newly divided to several groups. Also identification of other radiological signs is fundamental.

Incidence and prevalence of idiopathic pulmonary fibrosis are increasing. The integral part of diagnostics of idiopathic pulmonary fibrosis is high resolution computed tomography. Radiological image of idiopathic pulmonary fibrosis is usual interstitical pneumonia. On high resolution computed tomography are changes of typical usual interstitial pneumonia, possible usual interstitial pneumonia or signs which are not typical for usual interstitial pneumonia. There was made uniform scoring system which is quite simple and reproducible. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the prevalence of spoke-wheel pattern and typical symptoms of focal nodular hyperplasia (FNH) by means of dynamic contrast-enhanced ultrasonography (CEUS) in relation to lesion size. Methods: Twenty-eight patients were included in the trial, in whom, based on the CEUS, we raised suspicion of hypervascularized liver lesion; there were 30 lesions altogether. The final diagnosis of FNH was verified by means of CT, MRI or lesion biopsy. Majority of patients (26) were females, compared to 2 male, with average age of 33.3 years. Average lesion size was 45.6 mm. Besides the ultrasound examination, we used also "blood pool" ultrasound contrast agent of second generation, sulphur hexafluoride (BR1); we evaluated enhancement of the lesion until the late stage-within 5 min from application. Results: In lesions larger than 3 cm (n=20), stellate vascular enhancement was found in 19 cases (95.0%) early in arterial phase. As for lesions smaller than 3 cm (n=10), spoke-wheel pattern was observed only in 3 cases (30%) and lesions smaller than 2 cm practically did not show this phenomenon at all (n=1; 17%). Generally, symptom of spoke-wheel pattern was observed in 22 cases, i.e. in 73.3%. In total, central scar was present in 63.3% (n=19) of cases. In lesions larger than 3 cm, it was present in 85.0% (n=17), in lesions smaller than 3 cm in 20% (n=2). Conclusion: Contrast-enhanced ultrasonography can be the final diagnostic method for FNH larger than 3 cm which has typical spoke-wheel vessel structure on CEUS. If this phenomenon is not present and the central scar is not visible, specific diagnosis of FNH cannot be based solely on CEUS findings. [ABSTRACT FROM AUTHOR]
