Providing emergency care to victims of stroke is all about timing—the swifter the response of emergency medical services, the better the chances become for favorable patient outcomes. New Mobile Stroke Treatment Units (MSTU) outfitted with CT scanners and staffed with nurses, paramedics and CT technologists are helping to shave critical minutes off of stroke response times.

Doppler ultrasonography (US) is an effective and relatively low-cost tool in identifying patients with asymptomatic carotid stenosis who would most benefit from more invasive treatment, according to a study published in the February edition of Radiology.

When imaging acute ischemic stroke (AIS) patients, a new CT angiography imaging method proved to be a reliable tool for imaging selection, according to a Canadian study published online Jan. 29 in Radiology.

Time-resolved MR angiography (MRA) has proven itself a valuable tool in the quick assessment of vascular disease in stroke patients, according to a study published online Jan. 15 in Academic Radiology.

The American Society of Echocardiography and the European Association of Cardiovascular Imaging have joined together again to update recommendations on the quantification of cardiac chamber size and function, publishing the document in the January issue of the Journal of the American Society of Echocardiography.

When estimating myocardial blood flow (MBF) using four tracer kinetic analysis models, researchers have found no significant difference in diagnostic ability between methods, according to a study published online Dec. 18 in Radiology.

Combining dual-energy CT with coronary CT angiography (CTA) enhances accuracy when identifying coronary stenosis, according to a new study in the American Journal of Roentgenology. 

The most common liver disease in the U.S., nonalcoholic fatty liver disease (NAFLD), has been linked to coronary plaque, according to a study published today in Radiology.
