TL;DR: In this article, the authors reported two cases of myocarditis, in two young and previously healthy individuals, temporally related to the second dose of the mRNA-COVID-19 vaccine.

TL;DR: A 17 year old female patient with no significant past medical or surgical history who presented with several weeks of severe joint pain in the setting of a recent viral illness is presented, suggesting the etiology of PTS in this patient to be related to recent infection with SARS-CoV2 (COVID-19).

TL;DR: This article will provide a comprehensive overview on the past, present, and future of CEM, including its evolving role in the diagnostic and screening settings.

TL;DR: The first COVID-19 related cases of carotid artery thrombosis and acute leukoencephalopathy with multifocal hemorrhage are presented.

TL;DR: In this paper, the authors describe the lesions seen on magnetic resonance imaging (MRI) of three patients who developed neurological symptoms after receiving the ChAdOX1 nCoV-19 vaccine (Oxford/AstraZeneca).

TL;DR: This overview focuses on the recent advances of artificial intelligence methods - particularly supervised machine learning and deep learning - with respect to workflow, image acquisition and reconstruction, and image interpretation in patients with acute stroke, while also discussing potential pitfalls and future applications.

TL;DR: A high incidence of PE was found in lung parenchyma affected by COVID-19 pneumonia with a worse CT severity score and a greater number of lung lobar involvement compared with non-PE patients, and certain findings of non-contrast chest CT could be an indication for a CTPA.

TL;DR: Although MRI is not the modality of choice for evaluation of pulmonary opacities, it has similar capabilities in detection of COVID-19 pneumonia when compared to chest CT.

TL;DR: The first case to the authors' knowledge of a patient with acute coronary syndrome confirmed on catheter angiography and cardiac MRI is reported, found to additionally have a left ventricular thrombus and ultimately suffered an acute cerebral infarction.

TL;DR: Involvement of predominantly 4 or more zones on frontal chest radiograph can be used as predictive prognostic indicator of poorer outcome in COVID-19 patients.

TL;DR: The most common CT findings in CO VID-19 are GGOs with/without consolidation, reticulations, and air bronchogram, which mostly involved both lungs with peripheral distribution, however, COVID-19 might present with atypical manifestations or no abnormal findings in chest CT, which deserve clinicians' notice.

TL;DR: A review of the most recent medical imaging techniques used for the diagnosis of SARS-CoV-2 and their potential contributions to attenuate the pandemic can be found in this article.

TL;DR: In this article, a meta-analysis of the current literature on CXR imaging findings to determine the most common appearances of lung abnormalities in COVID-19 patients in order to equip medical researchers and healthcare professionals in their efforts to combat this pandemic.

TL;DR: A COVID-19 patient is presented with numerous atypical target-shaped, combined halo and reversed halo pulmonary lesions, in the absence of any other underlying disease.

TL;DR: In this paper, the authors used multivariable logistic regression to evaluate the relationship between coronary artery calcification (CAC) scores and patient outcomes and found that higher CAC was associated with higher intubation risk.

TL;DR: In this article, a previously healthy patient with COVID-19 showed biliary damage with elevated AST and ALT was seen in patients with co-infection, and the patient underwent a complicated course including intubation, multiple readmissions, and chronic abdominal pain.

TL;DR: CT-guided percutaneous MWA of perivascular and subdiaphragmatic HCC tumors is safe and effective and the local tumor recurrence and survival was not significantly different compared to control tumors.

TL;DR: An overview of the pathophysiology, clinical presentation and imaging findings of intra- and extralobar pulmonary sequestration are given, with particular reference to multidetector computed tomography as part of a powerful and streamlined diagnostic approach.

TL;DR: In this paper, a previously in-person 2-week introductory radiology elective was converted into a completely virtual experience using an internally developed, open-source, peer-reviewed, web-based teaching modules combined with virtual lectures, interdisciplinary conferences, and readout sessions of de-identified cases loaded to a DICOM viewer.

TL;DR: Nonsmooth tumor margins and incomplete tumor capsules observed by imaging are important for the preoperative prediction of MVI in HCC.

TL;DR: Summarizing evidence on diagnostic accuracy of LD- and ULD-CT for other chest pathology was not possible due to varying outcome measures, lack of precision estimates and heterogeneous study design and methodology.

TL;DR: GGO on CT has the highest diagnostic performance for COVID-19 pneumonia, followed by GGO plus consolidation and consolidation only, but moderate to low sensitivity and specificity suggest that CT should not be used as the primary tool for diagnosis.

TL;DR: In this article, the authors focus on the entire spectrum of abdominal tuberculosis and other diseases mimicking it with an emphasis on their imaging findings and propose a high index of clinical suspicion to aid early diagnosis and guide prompt initiation of appropriate treatment.

TL;DR: CT and MRI features that allow the diagnosis of infiltrative HCC and portal vein tumor thrombosis are shown and a particular point of interest includes the tips and tricks for differential diagnosis with potential mimickers of infiltratively HCC.

TL;DR: TBF and ADC alone and in combination are useful for differentiating IOIP from orbital lymphoma.

TL;DR: In this paper, the diagnostic performance of ultrasound attenuation imaging (ATI) for diagnosis and grading of hepatic steatosis with comparison to MRI-PDFF using mDIXON-Quant sequence was assessed.

TL;DR: In this paper, the role of semi-quantitative scoring in visual-coronary artery calcification score (V-CACS) for predicting the clinical severity and outcome in patients with COVID-19 was investigated.

TL;DR: This manuscript reviews potential applications of imaging modalities in the process of vaccine development and also goes over some of the imaging findings/pitfalls following vaccination.
