Eymen Ucisik, MD discusses a recently published AJR article aiming to explore the potential of the insular ribbon involvement on the initial MRI as a marker of tissue fate by analyzing serial follow up MRI findings and the affected patients’ clinical outcomes. It is relevant for the general radiologists and neurologists since it may help identify patients who could benefit from late-window reperfusion treatments or neuromodulation treatments.

Locoregional therapies for hepatocellular carcinoma perform differently when compared by rates of complete pathologic necrosis of lesions. Juliet Alla, MD discusses a new AJR study that demonstrates improved rates of complete pathologic necrosis for patients with HCC who underwent thermal ablation and TARE therapies, when compared to those who received TACE. Special guest Dr. Zachary Berman, an interventional radiologist who specializes in locoregional therapies for hepatocellular carcinoma, joins to discuss the implications for clinical practice.
