Ultra High-Resolution CT Valuable in Heart Stenosis Imaging

Jacqueline Latina’s team of researchers found “[i]nitial observations suggest UHR-CT may be effective in overcoming the limitation of conventional CT for accurately evaluating coronary artery stenoses in severely calcified vessels,” in a study published August 26, 2021, in Radiology: Cardiothoracic Imaging.

“This study’s initial experience with coronary angiography using ultrahigh-resolution CT in patients suspected of having coronary stenoses demonstrates promise for high diagnostic accuracy even in the setting of severe coronary calcification or prior stenting, representing a potentially substantial advance compared with conventional CT technology in this challenging patient population,” wrote the team.
