A non-invasive imaging examination is performed to determine if fatty or calcium deposits have built up in coronary arteries. Arteries are evaluated for narrowing, blockage, enlargement, or anomalies. CTA provides valuable information about the nature of blockages (soft plaque vs. hard calcified plaque) and the wall of the vessel. In the past, this information could only be obtained by invasive Cardiac Catheterization which shows only if an artery is narrowed. CTA identifies soft plaque. Artery narrowing with as little as 30% of soft plaque can rupture and result in a heart attack within seconds. Coronary CTA enables patients to know if they have coronary artery disease before it’s too late. With newer CT scanners such as those at SJRA this information can be obtained at a fraction of the dose of cardiac cath or stress perfusion imaging.
The Most Advanced CT Scanner in the World
SJRA is proud to announce that we are among the first in the world to have the latest, revolutionary CT scanner. The Definition Scanner integrates two X-ray sources and two sets of 64 detectors for the most detailed clinical images available. The Definition is also one of the fastest CT systems on the market. It can capture cardiac images in a few seconds.
