CT scan of cardiovascular disease: An update

SUMMARY

Coronary artery disease is the leading cause of death in the United States, in developing countries, coronary artery disease is rising rapidly. It’s been projected that by 2020, chronic diseases will account for almost three-fourths all deaths, 71% deaths due to ischemic heart disease. Early detection of coronary artery lesion helps to reduce mortality and improve quality of life by risk factors control and stabilize atherosclerotic plaques.

The newest commercially available MDCT scanners offer the greatest degree of spatial and temporal resolution owing to multidetector channels, fast gantry rotation times and thinner collimation. These parameters are important to creation of high definition coronary artery MDCT imaging.

In the case of acute chest pain, CT also proved safe, effective, low-cost, reduced the number of emergency visits and hospitalization. In addition to the accurate diagnosis, CT of coronary artery disease also evaluated other heart diseases such as congenital heart disease, pericardium, cardiomyopathy, heart valve

New developments such as FFR-CT, iFR-CT or Myocardial perfusion assessment show that computed tomography for cardiovascular disease diagnosis will be more potential in the future.

Keywords: coronary computed tomographic angiography, cardiac computed tomography, multi-detector computed tomography for cardiovascular disease diagnosis.
