Researchers Use 3D Fusion Imaging to Better Diagnose Coronary Artery Disease
Coronary artery illness is the most common type of coronary heart disease in response to the Centers for Disease Control and Prevention. About 18.2 million adults in the U.S. have coronary artery disease.
CT and MRI have established methods for noninvasive cardiac imaging and evaluation of coronary artery illness. CT is particularly helpful for high-decision images of the coronary anatomy, while cardiac MRI can provide info on the blood supply to the heart muscle without exposing sufferers to ionizing radiation.
Regardless of their complementary strengths, CT and MRI findings are sometimes analyzed separately, limiting the power to fully leverage the strengths of the two strategies.
Current strategies of mixing CT and MRI have limitations, as they look at solely a limited subset of the various aspects of coronary artery disease. Dr. von Spiczak and colleagues overcame these limitations by creating an approach that depicts all the accessible information from CT and cardiac MRI in a single 3-D picture.
They compared their method with conventional 2-D readouts in 17 sufferers who underwent cardiac CT and cardiac MRI on account of suspected or known coronary artery disease.
Typical 2-D readout of the images resulted in uncertain findings in eight cases. The new strategy helped solve the divergent findings in six of those instances.
Information from the 3-D fused picture helped correlate specific stenoses, or areas of narrowing in the coronary arteries, and their severity with possible cardiac scar tissue and ischemia—a condition in which parts of the heart muscle do not get sufficient blood.
