Cardiac Imaging Insider

Dear Cardiac Insider,

Hot off the press today comes welcome confirmation that adding a cardiac CT perfusion exam can salvage CT angiography (CTA) undertaken to evaluate stent patency. The question is arising with increasing frequency, of course, because so many stents are being implanted -- and in smaller and smaller coronary vessels that present the greatest challenges to CTA, according to the German study team.

Looking for in-stent restenosis is a challenging but critical job that has few noninvasive alternatives; neither MRI nor SPECT myocardial perfusion imaging does an adequate job alone. You'll find the details of this U.S. National Institutes of Health-funded study here.

Coronary CTA (CCTA) is also plagued by too many inappropriate referrals. But as reported last week at the U.K. Radiological Congress in Liverpool, following just a few simple guidelines can help ensure that every CCTA examination is using the resources and the radiation appropriately. Question one: Can the patient hold his or her breath? Find out how a hospital in Plymouth got things on track by clicking here.

Also from the U.K. come new clinical guidelines on PET/CT to ensure those exams, in the heart and elsewhere, are being ordered appropriately.

Cardiac PET/MRI, the newest kid on the block, is making important inroads, according to researchers from Essen, Germany, who found parity between FDG-PET and MRI in a story you'll find here.

Meanwhile, a team from Hannover, Germany, is focusing its efforts on inflammation. The group has found that an established treatment for cancer patients can offer a novel therapeutic approach to decrease the levels of inflammation in the atherosclerotic plaques of patients with cardiovascular disease.
