COVID-19 vaccine associated myocarditis on short-axis 1.5T MRI images of a 19-year-old man who presented with chest pain three days following the second dose of an mRNA COVID-19 vaccine.

New cardiac MRI analysis offers updated insight into long-term impact of vaccine-related myocarditis

Months after their initial myocarditis diagnosis, late gadolinium enhancement (LGE) was observed in 62% of patients on follow-up cardiac MRI.

Statin reduces risk for non-obstructive CAD patients but no significant risk reduction for aspirin

The results of a study published in Radiology: Cardiothoracic Imagincall into question the value of initiating aspirin therapy in certain instances.

Heartflow FFR-CT allows noninvasive assessment of a patient'c coronary arteries without the need for a diagnostic angiogram.

VIDEO: HeartFlow FFR-CT sees increased interest after inclusion in the 2021 Chest Pain Guidelines

HeartFlow’s non-invasive cardiac computed tomography derived fractional flow reserve (FFR-CT) technology enables FFR values for the entire coronary tree of a patient using just a CT scan. This can show the significance of any coronary plaque lesions and if a patient needs to be sent to the cath lab for revascularization, or if they can be treated medically.

Key lessons from pandemic-era virtual education for med students

An Academic Radiology paper explores what worked, what didn't, and strategies for future improvement. 

An example of COVID vaccine caused axillary adenopathy. The woman has a family history of breast cancer, but this lesion, seen on breast ultrasound, tested negative in an RSNA study.

Experts suggest new follow-up imaging protocols for vaccine-related lymphadenopathy

New research shows that persistent lymph node swelling observed on imaging can persist beyond 12 weeks post-vaccination for up to 50% of women.

Stroke care still lags among certain Medicare populations

Despite increases of 250% for CTA and 428% for CTP, researchers observed lower rates of neuroimaging utilization among rural residents, older individuals (80 years and above), women and Black patients.

Disparities evident as CT stroke imaging rises sharply over 7-year period

Utilization of head CT perfusion (CTP) for imaging stroke patients spiked 428% between 2012 and 2019. Curiously, the uptrend was associated with higher mortality up to a year after discharge.

CT scans find prone position increases lung recruitment for COVID-19 patients

Using CT scans and EIT, researchers from an Italian hospital shed light on the specific benefits of the prone position for intubated COVID-19 patients. 

Around the web

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care. 

Richard Heller III, MD, RSNA board member and senior VP of policy at Radiology Partners, offers an overview of policies in Congress that are directly impacting imaging.
