COVID-19

Outside of the loss of human life due to the COVID-19 pandemic, the past two years have greatly affected hospitals, health systems and the way providers deliver care. Healthcare executives are grappling with federal monetary assistance, growing burnout rates, workforce shortages and federal oversight of vaccines and testing. This channel is also designed to update clinicians on new research and guidelines regarding COVID patient treatment strategies and risk assessments.

In the study, patients who had recovered from an COVID infection were injected with a small amount of the 89Zr-labeled radiotracer before undergoing a uExplorer PET/CT scan.

A study published this week in Radiology found that 12 months after hospitalization for COVID pneumonia, 93% of patients’ lung abnormalities had cleared up on follow-up chest CT scans.#covidpneumonia #groundglassopacities

Authors of the new paper noted that radiologists should be highly suspicious of pulmonary embolism and DVT when they encounter these findings on chest CT exams of COVID patients.

An interpretable AI tool that detects COVID-19 on chest radiographs underwhelmed researchers in a recent analysis published in Radiology: Artificial Intelligence. 

COVID ventilation complications

Radiologists involved in the care of these patients should be especially vigilant in identifying the signs of complications, experts cautioned in a new Clinical Imaging research paper.

“Visual techniques are not enough to correctly classify nodes in patients after COVID-19 vaccination,” experts shared in EJR.

Patients who received an injection had an infection rate of 2.2% at 4-month follow-up. In comparison, the infection rate for the general population in Massachusetts was 7.5% during the same period.

Unique to radiologists is that their workloads have not yet declined to the pre-pandemic levels seen in 2019 like other specialties have started to witness.

Whole-body imaging reveals clinically undetectable blood clots in patients after their first dose of AstraZeneca's COVID vaccine.

The funds will be allocated specifically toward neuroimaging and cognitive and immunological tests to explore if and how mild and asymptomatic SARS-CoV-2 infections have a long-lasting impact on neurocognitive function.

There is not agreement among the top structural heart experts if CT is required for left atrial appendage occlusion (LAAO), but a Henry Ford Hospital study shows it can improve outcomes.

Ron Blankstein, MD, Brigham and Women's Hospital, explains recent advances in coronary computed tomography angiography (CCTA) technology. 

With the elevation of cardiac CT to a 1A indication in the 2021 Chest Pain Guidelines, there has been a large amount of interest in starting coronary artery CT angiography (CCTA) programs.
