Background and purpose Perfusion Computed Tomography (CTp) is an imaging technique which allows quantitative and qualitative evaluation of tissue perfusion through dynamic CT acquisitions. Since CTp is still considered a research tool in the field of abdominal imaging, the aim of this work is to provide a systematic summary of the current literature on CTp in the abdominal region to clarify the role of this technique for abdominal cancer applications. Materials and Methods A systematic literature search of PubMed, Web of Science, and Scopus was performed to identify original articles involving the use of CTp for clinical applications in abdominal cancer since 2011. Studies were included if they reported original data on CTp and investigated the clinical applications of CTp in abdominal cancer. Results Fifty-seven studies were finally included in the study. Most of the included articles (33/57) dealt with CTp at the level of the liver, while a low number of studies investigated CTp for oncologic diseases involving UGI tract (8/57), pancreas (8/57), kidneys (3/57), and colon–rectum (5/57). Conclusions Our study revealed that CTp could be a valuable functional imaging tool in the field of abdominal oncology, particularly as a biomarker for monitoring the response to anti-tumoral treatment.

After 15 years from its advent in the clinical field, coronary computed tomography (CCTA) is now widely considered as the best first-step test in patients with low-to-moderate pre-test probability of coronary artery disease. Technological innovation was of pivotal importance for the extensive clinical and scientific interest in CCTA. Recently, the advent of last generation wide-coverage CT scans paved the way for new clinical applications of this technique beyond coronary arteries anatomy evaluation. More precisely, both biventricular volume and systolic function quantification and myocardial fibrosis identification appeared to be feasible with last generation CT. In the present review we would focus on potential applications of cardiac computed tomography (CCT), beyond CCTA, for a comprehensive assessment patients with newly diagnosed cardiomyopathy, from technical requirements to novel clinical applications.

Introduction: Cutaneous leishmaniasis is one of the health concerns in Iran. Numerous studies have examined the role of blood type in people with the disease. Therefore, this study aimed to investigate the prevalence of leishmaniasis in different blood groups as a review in Iran. Materials and Methods: For this review, two researchers evaluated the extracted articles in terms of relevance to the purpose of the study after searching four databases, including Scopus, Web of Science, PubMed, and Science Direct. Literature reports on the prevalence of leishmaniasis in different blood groups in Iran until the end of March 2021. Relevant information included study time, study tool, number of subjects, mean age, and the relationship between blood type and infection which were recorded in Excel form. Results: After searching, screening, and qualitative evaluation of the studies, out of 135 identified articles, five papers met the required requirements. These five articles were published from 1999 to 2012, three studies examined the relationship between cutaneous leishmaniasis with different age groups. Also, three studies experimentally evaluated the relationship between cutaneous leishmaniasis with different human blood groups. Conclusion: According to the results of the present review, cutaneous leishmaniasis is more common in some blood groups. Studies have shown that Rh-negative blood groups with B alleles are more affected by cutaneous leishmaniasis than others; however, more studies are required.

Lung ultrasound has been recognized as a valid imaging method for diagnosing and monitoring COVID-19 pneumonia in pregnant women. The present review aimed to summarize the main findings reported in the literature and international guidelines on the role of lung ultrasound in the care of pregnant women affected by COVID-19. A search strategy was developed and applied to PubMed, Scopus, Web of Science and EMBASE to identify previous papers reporting the utility of ultrasound in diagnosing and monitoring COVID-19 pneumonia. The search retrieved 369 articles and 23 of these were selected for analysis. The articles mainly focused on the definition of the procedure, development of training programs for obstetricians managing pregnant women with suspicion of COVID-19 and definition of scoring systems. The clinical applications of lung ultrasound in this setting have also been described. This review could encourage obstetricians to learn lung ultrasound to use during critical events like a pandemic.

Coronary Syndromes

In the context of chronic coronary syndromes (CCS), coronary computed tomography angiography (CCTA) has gained broad acceptance as a noninvasive anatomical imaging tool with ability of excluding coronary stenosis with strong negative predictive value. Atherosclerotic plaque lesions are independent predictors of cardiovascular outcomes in high risk patients with known coronary artery disease (CAD). Calcium detection is commonly expressed through the coronary artery calcium score (CACS), but further research is warranted to confirm the powerness of a CACS-only strategy in both diagnosis and prognosis assessment. Recent studies evidence how defined plaque composition characteristics effectively relate to the risk of plaque instabilization and the overall ischemic burden. Fractional flow reserve from CCTA (FFR-CT) has been demonstrated as a reliable method for noninvasive functional evaluation of coronary lesions severity, while the assessment of perfusion imaging under stress conditions is growing as a useful tool for assessment of myocardial ischemia. Moreover, specific applications in procedural planning of transcatheter valve substitution and follow-up of heart transplantation have gained recent importance. This review illustrates the incremental role of CCTA, which can potentially revolutionize the diagnosis and management pathway within the wide clinical spectrum of CCS.
