Sanjay Parekh, PhD, senior market analyst with Signify Research, explains how some radiology AI is being adopted outside of radiology departments to improve care.

Contrary to older research that showed neuroimaging emerging as the single most dominating cost contributor in ischemic stroke care for older Americans, a new study shows treatment and other line items account for bigger slices of the bill.

Bibb Allen, MD, FACR, chief medical officer of the American College of Radiology (ACR) Data Science Institute, explains the trend of using AI for the automated detection of stroke on computed tomography (CT) imaging and the need to include radiologists on the stroke care team.

Emergency patients diagnosed with transient ischemic attack are supposed to receive, per multiple society guidelines, a complete imaging workup as soon as possible—preferably within 48 hours of ED discharge.

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.

Physicians may not be aware of such devices' intended use, with potential for misdiagnosis resulting in patient injury or death, the agency announced. 

Increased volume has led to stress among endovascular stroke physicians, with some hospitals relying on interventional rads to relieve the strain. 

Researchers tracked data from more than 1,000 patients who received care from 2014 to 2020.
