The location of unilateral axillary lymphadenopathy after COVID-19 vaccination compared with that of metastasis from breast cancer without vaccination
ConclusionThe presence of deep axillary lymphadenopathy may be an important factor for distinguishing post-vaccination lymphadenopathy from metastasis. The number of axillary lymph nodes may also help.

Unusual Lesion in the Splenium of the Corpus Callosum and COVID-19 Infection: A Case Report
We report a case of CLOCCS, one of the rare neurological complications of SARS-CoV-2 infection.Teaching Point: The imaging features of the cytotoxic lesion of the corpus callosum (CLOCCS) on magnetic resonance imaging should be known by every radiologist, to make the positive diagnosis and prevent misdiagnosis, especially in the setting of a COVID-19 infection.

Short-term outcome of late gadolinium changes detected on cardiovascular magnetic resonance imaging following coronavirus disease 2019 Pfizer/BioNTech vaccine-related myocarditis in adolescents
ConclusionThis study on post-vaccine myocarditis demonstrates residual lesions with persistent areas of late gadolinium enhancement/myocardial fibrosis with ongoing myocardial oedema after resolution of the initial myocardial oedema a few weeks after Pfizer/BioNTech vaccination. There is an urgent need to recognise and fully investigate the outcome of post-vaccination myocarditis.

Cardiac magnetic resonance T2* mapping in patients with COVID-19 pneumonia is associated with serum ferritin level?
This study aims to assess myocardial structure by T2*-mapping which is a non-invasive gold-standard imaging tool for the assessment of cardiac iron deposition in patients with COVID-19 pneumonia without significant cardiac symptoms. Twenty-five patients with COVID-19 pneumonia and 20 healthy subjects were prospectively enrolled.Cardiac volume and function parameters, myocardial native-T1, and T2*-mapping were measured. The association of serum ferritin level and myocardial mapping was analyzed. There was no difference in terms of cardiac volume and function parameters. The T2*-mapping values were lower in patients with COV...

Ventricular function and tissue characterization by cardiac magnetic resonance imaging following hospitalization for multisystem inflammatory syndrome in children: a prospective study
ConclusionAlthough many children with MIS-C present acutely with cardiac dysfunction, residual myocardial damage 6 –9 months afterward appears minimal. Long-term implications warrant further study.

Cardiovascular magnetic resonance imaging and spectroscopy in clinical long-COVID-19 syndrome: a prospective case –control study
The underlying pathophysiology of post-coronavirus disease 2019 (long-COVID-19) syndrome remains unknown, but increased cardiometabolic demand and state of mitochondrial dysfunction have emerged as candidate m...

Brain MRI findings in COVID-19 patients with PRES: A systematic review
Numerous case reports and case series have described brain Magnetic Resonance Imaging (MRI) findings in Coronavirus disease 2019 (COVID-19) patients with concurrent posterior reversible encephalopathy syndrome (PRES).

Cross-sectional analysis of follow-up chest MRI and chest CT scans in patients previously affected by COVID-19
ConclusionsThe agreement between MRI and CT was overall good. MRI was very sensitive for GGOs, consolidation and interlobular septal thickening and overall specific for most findings. DWI could be a reputable imaging biomarker of inflammatory activity.

Acute and chronic cardiac involvement in COVID-19
CONCLUSION: Depending on the severity of the infection, cardiac involvement in a COVID 19 infection is observed in up to 50% of the patients. Besides echocardiography as the first-line examination method, cardiac magnetic resonance imaging (MRI) for assessment of the myocardial structure and cardiac computed tomography (CT) for assessment of coronary arteries and to rule out intracardiac thrombus formation represent important imaging modalities. The most important cardiac manifestations in COVID 19 infections are ischemic and inflammatory diseases. The imaging diagnostics play an important role in the acute as well as in t...

Neurological symptoms and neuroimaging alterations related with COVID-19 vaccine: Cause or coincidence?
Although vaccination against Coronavirus disease-2019 (COVID-19) is still occurring, several adverse effects temporally related to these vaccines are already being reported, even if through isolated case reports. In the present study, we 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). The first patient presented with an ischemic stroke in the posterior limb of the left internal capsule, two days after vaccination.

Differences in Cardiac Magnetic Resonance Imaging Markers Between Patients With COVID-19-associated Myocardial Injury and Patients With Clinically Suspected Myocarditis
We examined CMRI of patients with COVID-19 and elevated high-sensitivity serum troponin levels performed between March 31st and May 5th and compared them to CMRI of patients without SARS-CoV-2 infection with suspected myocarditis in the same time period. For this purpose, we evaluated Lake-Louise Criteria for myocarditis by determining nonischemic myocardial injury via T1-mapping, extracellular volume, late gadolinium enhancement, and myocardial edema (ME) by T2-mapping and fat-saturated T2w imaging (T2Q). Results: A total of 15 of 18 (89%) patients with COVID-19 had abnormal findings. The control group consisted of...
