(DIAGNOSTIC IMAGING) – Patients suspected of having coronary stenoses may benefit from ultra-high-resolution CT, according to a recent study that showed high diagnostic confidence in severely calcified coronary atherosclerotic disease.
Ultra-high-resolution CT (UHR-CT) may be more accurate than conventional CT for evaluating coronary artery stenoses in severely calcified vessels, a new study suggests.
The study, published in Radiology, Cardiothoracic Imaging, included 15 patients enrolled between November 2019 and May 2021, with an average age of 67 and a history of coronary artery disease (CAD) who underwent UHR-CT within 30 days prior to cardiac catheterization.
“We believe our data show promise that ultra-high-resolution CT (UHR-CT) with 0.25 mm detector width can overcome a major limitation of coronary CT, i.e., the limited interpretation of the coronary artery lumen in the presence of severe calcification,” Armin A. Zadeh, MD, PhD, MPH, director of cardiac computed tomography and associate professor of medicine at Johns Hopkins University, told Diagnostic Imaging. Please read more in Diagnostic Imaging.
