ABSTRACT
Coronary CT angiograms are commonly performed for the evaluation of coronary artery disease and coronary arterial anatomy. However, extracardiac findings are frequently detected on these examinations and often can explain patients' underlying symptoms, having a significant impact on patient management. Here in, we discuss three cases of incidentally detected novel COVID-19-infected pneumonia (NCIP). This case series highlights the image findings in NCIP and emphasizes the importance of evaluating all organs in the field of view on coronary CT angiograms. In addition, with the ongoing outbreak of COVID-19 and exponentially increasing incidence throughout the world, this report stresses the need for including NCIP in the differential diagnosis of patients with typical image findings in at-risk populations, as early diagnosis is crucial for appropriate patient management and post-exposure recommendations.

Newer structured reporting manners, the reporting and data system (RADS), have made vast steps in improving standardized and structured reporting, allowing better communication between radiologists and referring providers. This has been implemented in several fields: breast (BI-RADS), lung (Lung-RADS), liver (LI-RADS), thyroid (TI-RADS), prostate (PI-RADS), and in cardiovascular radiology (CAD-RADS). The field of nuclear cardiology began its efforts of standardization years ago; however, a widespread standardized reporting structure has not yet been adopted. Such an approach in nuclear cardiology, the nuclear cardiology reporting and data system (NCAD-RADS), will assist radiologists and treating clinicians in conveying and understanding reports and determining the appropriate next steps in management. By linking explicit findings to defined recommendations, patients will receive more consistent and appropriate care.

Coronavirus disease 2019 (COVID-19), the first pandemic caused by a human infecting coronavirus, has drawn global attention from the first time it appeared in Wuhan city of China in late December 2019. Detection of the responsible viral pathogen, named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by WHO, and its possible pathogenesis lead to the forming of many hypotheses about the factors that may affect the patients' outcome. One of the SARS-CoV-2 infection concerns was the potential role of angiotensin-converting enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs) in COVID-19 patients' morbidity and mortality. Studies demonstrated that because SARS-CoV-2 uses human ACE2 cell receptors as an entry receptor to invade the cells, there might be an association between antihypertensive drugs such as RAAS inhibitors (specifically ACEIs and ARBs) and the COVID-19 disease. Data are scarce and conflicting regarding ACEI or ARB consumption and how it influences disease outcomes, and a single conclusion has not been reached yet. According to the literature review in our article, the most evidentially supported theory about the use of RAAS inhibitors in COVID-19 is that these medications, including ACEI/ARB, are not associated with the increased risk of infection, disease severity, and patient prognosis. However, further studies are needed to support the hypothesis.
ABSTRACT
PET has been founded as a useful technique in the staging, restaging, prognostication, and treatment planning for numerus cancers, with an incremental application in precision oncology. This paper summarized the current state-of-the-art application of PET/CT in the management of patients with peripheral nerve tumors. Furthermore, the potential clinical uses of emerging themes and technological advances are reviewed, consisting hybrid PET/MR imaging and alternative radiotracers for the application in peripheral nerve oncology.
