State of the Art: Coronary CTA


Head of Imaging Department Tehran Heart Center, Tehran,Iran



Since the introduction of computed tomography about 50 years ago, imaging of beating heart has been a big challenge for medical imaging innovators. Imaging the anatomy and physiology of heart demands temporal, spatial, and contrast resolution greater than for any other organ system in body. Immense progress has been achieved in using CT for evaluation of coronary stenosis, plaque composition, cardiac function, myocardial perfusion and regional ventricular wall motion. Major accomplishments and future directions of cardiac CTA will be discussed in this review.
