Abstract
Limitations of CT angiography and invasive coronary angiography are that their ability to distinguish the physiologic effects of coronary artery stenosis and to detect myocardial ischemia is quite low. Further evaluation of myocardial function such as radioisotope scan or stress function tests is often required after identifying coronary artery stenosis lesions that also requires costs and additional radiation exposure. With the advance of CT and MRI, myocardial perfusion is easily and reliably assessed. Myocardial blood flow and volume can be calculated using dynamic scan. The scan protocols, how to assess the perfusion study using CT and MR, and artifacts and limitations of CT and MR perfusion study will be described and illustrated.
