Beyond business as usual: Radiology residency educational response to the COVID-2019 pandemic.
The COVID-19 pandemic has disrupted standard hospital operations and diagnostic radiology resident education at academic medical centers across the country. Deferment of elective surgeries and procedures coupled with a shift of resources toward increased inpatient clinical needs for the care of COVID-19 patients has resulted in substantially decreased imaging examinations at many institutions. Additionally, both infection control and risk mitigation measures have resulted in minimal on-site staffing of both trainees and staff radiologists at many institutions. ⋯ We describe our experience adapting to the challenges in educational interruptions and clinical work reassignments of 41 interventional and diagnostic radiology residents at a large academic center. We highlight opportunities for collaboration and teamwork in creatively adjusting and planning for the short and long-term impact of the pandemic on resident education. This experience shows how the residency educational paradigm was shifted during a pandemic and can serve as a template to address future disruptions.

To evaluate the diagnostic performance for margin assessment of specimen radiography (SR) in breast conserving surgery (BCS) using radioactive I125-seed localization (RSL). ⋯ SR has a moderate diagnostic performance for margin involvement using RSL. A more accurate intraoperative margin assessment tool is warranted.

The present study was carried out to investigate any possible linkage between cerebral grey matter volumetric, iron changes, white matter's lesions load and serum iron levels in a group of relapsing-remitting multiple sclerosis (RRMS) patients. ⋯ Smaller cortical and subcortical grey matter volumes in RRMS patients compared to HCs were detected. None of the volumetric measures showed any association with patients' disability status. RRMS patients showed increased iron levels in the PT, GP and cortex and decreased levels in the TH and serum.

Pregnant women with 2019 novel coronavirus disease (COVID-19) pneumonia are a special group of patients in the pandemic. We report a case of pregnant woman with COVID-19 pneumonia in the second trimester. Clinical and imaging features of the patient were similar to that reported in the literatures for both perinatal patients and non-pregnant patients.

The chest computed tomography (CT) features of coronavirus disease 2019 (COVID-19) and Streptococcus pneumoniae pneumonia (S. pneumoniae pneumonia) were compared to provide further evidence for the differential imaging diagnosis of patients with these two types of pneumonia. ⋯ The findings of GGO, the crazy paving sign, and abnormally thickened interlobular septa on chest CT were significantly higher in COVID-19 than S. pneumoniae pneumonia. The most important differential points on chest CT signs between COVID-19 and S. pneumoniae pneumonia were whether disease lesions were distributed in entire lung lobes and segments and whether the crazy paving sign, interlobular septal thickening, and consolidation lesions were found.
