On this podcast, Edgar Perez, MD discusses MRI findings of COVID related-Disseminated Leukoencephalaopathy, which should remain an important differential consideration in COVID patients with neurologic manifestations.

Additional wireless localization options exist, including use of radioactive seeds, magnetic markers, radar/infrared reflectors, or most recently a radiofrequency identification tags, which address some of the disadvantages involved in wire localization. Matthew Petterson, MD discusses results an AJR study of one year of use at a single institution that suggests that RF tag localization is a feasible alternative to wire localization.

Jordan Perchik, MD discusses a new AJR study in which a team of radiologists evaluate multiple imaging parameters and tumor metrics to assess for characteristics to predict pathologic response prior to resection.

This podcast by Ben Kipper, MD examines a paper comparing outcomes between thermal ablation and stereotactic body radiation therapy following transarterial chemoembolization and how those outcomes might affect clinical treatment plans going forward.

Alicia Chen, MD discusses a timely meta-analysis by Dr. Choudhery and colleagues that found the pooled positive predictive value for AD without a known cause on DBT is 35%, the great majority of which represents invasive disease. This finding warrants tissue sampling.

Important findings include that the technique is safe and fairly high yield for lesions 20 mm or less and that features such as nodular.

All nodules contain pathologic confirmation from biopsy.

In this podcast, Amber Liles, MD discusses how cardiac MRI and cardiac CT angiography perform in comparison to TTE in terms of prediction of stroke recurrence.

Article: https://www.ajronline.org/doi/abs/10.2214/AJR.20.23953 Shrey Patel, MD discusses a new AJR article on whether using an unconventional DWI technique, readout-segmented echo-planar imaging, can improve image quality and differentiate disease activity in patients with axial spondyloarthritis.
