Abstract	Background: The aim of this study was to evaluate the effect of coronary artery calcification on disease severity and prognosis in patients with coronavirus disease-2019 (COVID-19). Materials and methods: One hundred and forty-one patients with COVID-19 were included in this study. The severity of pulmonary involvement and calcification of coronary arteries were assessed by computed tomography scan and calcification was classified by two methods: Weston and segmental. In both the methods, patients were divided into three groups with scores of 0, 1-6, and 7-12, which are called groups 1, 2, and 3, respectively. Results: The mean age of patients was 54.26 ± 14.55. Difference in score of pulmonary involvement was reported to be significant between deceased and discharged patients (11.73 ± 5.26 and 7.28 ± 4.47, Conclusion: Coronary artery calcification in patients with COVID-19 has a significant association with poor prognosis. However, no significant relationship was observed between this issue and the severity.

Abstract	Purpose: This study aimed to examine the relationship of perivascular adipose tissue (PVAT) stranding in coronary computed tomography angiography (CCTA) with high-sensitivity C-reactive protein (hsCRP) and the determinants of PVAT stranding in coronary artery disease (CAD) patients. Material and methods: This retrospective cross-sectional study was done by collecting data from CAD patients who were referred to Rajaie Cardiovascular Centre between January 2018 and September 2020, with CCTA and hsCRP test 72 hours apart from the CCTA. PVAT stranding was defined as irregular obscuration of PVAT adjacent to the coronary arteries. An attempt was made to find a correlation between included variables and PVAT stranding by comparing them between 2 groups: patients with and without PVAT stranding. Results: From 92 patients, 31 participants had PVAT stranding, and statistically significant higher levels of hsCRP were detected in them (p = 0.007). We demonstrated significantly higher prevalence of history of hyperlipidaemia (OR = 3.83, p = 0.029), high-risk plaque features (OR = 11.80, p = 0.015), and obstructive coronary luminal stenosis (OR = 3.25, p = 0.025) in patients with PVAT stranding. Also, significantly higher PVAT attenuation was detected in patients with PVAT stranding (p < 0.001) independently from mean attenuation of epicardial fat. Conclusion: PVAT stranding could be used as a novel non-invasive marker in CCTA of CAD patients. More studies focusing on patient outcomes are required to better evaluate the reliability and prognostic value of this marker.

Abstract	Background: The aim of this study was to evaluate the effect of coronary artery calcification on disease severity and prognosis in patients with coronavirus disease-2019 (COVID-19). Materials and Methods: One hundred and forty-one patients with COVID-19 were included in this study. The severity of pulmonary involvement and calcification of coronary arteries were assessed by computed tomography scan and calcification was classified by two methods: Weston and segmental. In both the methods, patients were divided into three groups with scores of 0, 1–6, and 7–12, which are called groups 1, 2, and 3, respectively. Results: The mean age of patients was 54.26 ± 14.55. Difference in score of pulmonary involvement was reported to be significant between deceased and discharged patients (11.73 ± 5.26 and 7.28 ± 4.47, P = 0.002, respectively). In Weston score system, the chance of recovery of Group 1 patients was significantly higher than Group 3 (odds ratio [OR] =6.72, P = 0.05, 95% confidence interval [CI] =1.901–50.257). Similar results were observed in the segmental scoring system (OR =6.34, P = 0.049, 95% CI =1.814–49.416). Despite the higher chance of severe disease in patients with coronary artery calcification, this increase was not statistically significant in either Weston or segmental methods (OR =0.47, P = 0.23 and OR =0.85, P = 0.79, respectively). Conclusion: Coronary artery calcification in patients with COVID-19 has a significant association with poor prognosis. However, no significant relationship was observed between this issue and the severity.

Abstract	Context: Coronary artery disease (CAD) is the foremost cause of death in many countries and hence, its early diagnosis is usually concerned as a major healthcare priority. Coronary artery calcium scoring (CACS) using either electron beam computed tomography (EBCT) or multislice computed tomography (MSCT) has been applied for more than 20 years to provide an early CAD diagnosis in clinical routine practice. Moreover, its association with other body organs has been a matter of vast research. Evidence acquisition: In this review article, techniques of CACS using EBCT and MSCT scanners as well as clinical and research indications of CACS are searched from PubMed, ISI Web of Science, Google Scholar and Scopus databases in a time period between late 1970s through July 2013 and following appropriate selection, dealt with. Moreover, the previous and ongoing research subjects and their results are discussed. Results: The CACS is vastly applied in early detection of CAD and in many other research fields. Conclusions: CACS has remarkably changed the screening techniques to detect CAD earlier than before and is generally accepted as a standard of reference for determination of risk of further cardiac events.

Abstract	Purpose: To retrospectively assess the correlation between pulmonary arterial obstruction index (PAOI) and right lateral ventricular wall thickness with in-hospital mortality in patients with acute pulmonary embolism. Methods: CT angiography (CTA) of 55 consecutive patients (30 males; 25 females; mean age ± SD, 59 ± 11 years) with proven acute pulmonary embolism was investigated. PAOI was determined according to the Qanadli score on CTA. Right ventricular lateral wall thickness was also measured, and patients' in-hospital mortality was recorded. The correlation between PAOI and mortality, right ventricular lateral wall thickness and mortality, and PAOI and right ventricular lateral wall thickness was evaluated. Results: PAOI was 23.6 and 10.4 in patients with and without in-hospital mortality, respectively (P < 0.001). Right ventricular lateral wall thickness was 8.7 mm and 7.5 mm in patients with and without in-hospital mortality, respectively (P < 0.001). PAOI more than 21.5 and right ventricular lateral wall thickness more than 8.75 were predictive of in-hospital mortality with a high accuracy. Also, PAOI and right ventricular lateral wall thickness had a significant correlation with each other (P < 0.001; r = 0.695). Conclusion: PAOI and right ventricular lateral wall thickness on CTA were highly predictive of in-hospital mortality in patients with pulmonary embolism. Right ventricular lateral wall thickness and PAOI had a significant correlation with each other as well.

Abstract	Background: Recognition of imaging findings in pulmonary emboli and their association with homodynamic factors is important for prompt diagnosis, treatment, and reduction of its morbidity. The main objective in current study was to determine the correlation between CT obstructive index in pulmonary thromboembolism and systolic blood pressure at the time of diagnosis. Materials and Methods: In this observational cross-sectional comparative study, 70 consecutive patients with pulmonary emboli admitted in Modarress Hospital (Tehran, Iran) among 2013-17 were enrolled and correlation between CT obstructive index on pulmonary CT angiography and systolic blood pressure at the time of diagnosis was determined. Results: The correlation between CT index and hypotension (systolic blood pressure≤90) in our studied patients was significant (P=0.0001) and the mean CT index in hypotensive and normotensive patients was 56.4% and 27.5%, respectively. The CT obstructive index cut-off point of 53.75% resulted in sensitivity and specificity of 87.5% and 96.3%, for hypotension prediction. Conclusion: According to the obtained results it may be concluded that there is significant correlation between CT obstructive Index in patients with pulmonary thromboembolic and systolic blood pressure at the time of diagnosis and be calculating the CT obstructive index the possibility of hypotension related to massive emboli could be predicted.

Abstract	Behcet's disease is an autoimmune disease most commonly seen in the Middle East. Although primarily known with painful oral and genital ulcers, it can lead to vasculitis. Therefore, several associated complications such as thrombotic syndromes, aneurysmal arterial disease may arise. In many cases, it might be difficult to make the diagnosis purely based on clinical grounds; however, imaging plays an important role for both diagnosis and assessment of the disease's complications. We provide a comprehensive review of the most notable imaging findings of Behcet's disease.

Abstract	Background: Chest X-ray (CXR) is a common imaging modality that could impact immediate decision-making for acute chest pathologies. We sought to examine the non-radiologists proficiency of diagnosing acute pathologies manifest on CXR. Methods: We selected 9 clinical vignettes, each associated with a CXR, wherein only a single acute chest pathology was manifest. We also added a low-risk vignette associated with a normal CXR. We built an electronic survey with the CXR-embedded vignettes and also inquired about the participants' confidence in the diagnosis, and prior exposure to the topics. We distributed the survey to senior medical students and general practitioners (GPs) in Tehran, Iran. We scored each correct answer per each vignette as 1 and each incorrect answer as 0; leading into a sum score from 0 to10 for the entire survey for each participant. Results: Of the 136 candidates, 100 had legible survey results (67 medical students and 33 GPs). The overall score (mean [standard error]) was 3.57 [0.20], with no significant difference between the students and GPs (P = 0.15). The lowest rate of correct response occurred for acute respiratory distress syndrome (8%), foreign body (12%), and normal CXR (15%), while the best-answered vignettes were diaphragmatic herniation (77%) and pneumoperitoneum (67%). Self-reported confidence was associated with correct response for pneumoperitoneum, tension pneumothorax, and pulmonary edema (P < 0.05 for all). Conclusions: Diagnostic proficiency of practitioners for acute chest pathologies in our study was poor, including for distinction of a normal CXR. Such dramatic knowledge deficiencies for common or life-threatening chest pathologies should be prioritized in the educational and continuous education curricula. Secure electronic tools for transferring the CXRs to specialists in case of acute pathologies would be an interim pragmatic alternative.

Abstract	Background: Myocardial bridging (MB) is a congenital anomaly in which a segment of a major epicardial coronary artery courses through the myocardium. This anomaly can lead to myocardial ischemia, arrhythmia, and even death. The effectiveness of coronary computed tomographic angiography (CCTA) in the detection of MB and its morphological features, and the accuracy of invasive coronary angiography (ICA) in the evaluation of systolic compression have been shown in some prior studies. Objectives: The present study aimed to evaluate the correlation between the depth and the length of MB as determined using CCTA, and the degree of luminal narrowing of the involved tunneled segment as calculated using the ICA. Patients and methods: For this study, 109 consecutive patients diagnosed with myocardial bridging using CCTA, and who had already undergone ICA, were studied. The depth and length of the MB was determined in the CCTA, while the degree of systolic compression was calculated in the ICA. The correlation between the depth and length of the MB and the systolic compression were then evaluated. Results: The degree of systolic compression was found to be correlated with the depth of the MB. However, there was no correlation between the length of the MB and the degree of systolic compression. Conclusion: The systolic compression of the MB was influenced by the depth of the tunneled segment, not by its length.
