Clinical utility of computed tomography and magnetic resonance techniques for noninvasive coronary angiography

Abstract

Noninvasive coronary angiography is a rapidly developing technique and currently not an alternative to CCA in all cases. All three methods are currently used clinically in certain centers with appropriate expertise. Selective use should prove both cost-effective and provide a safer, less-invasive method for patients to determine the need for medical versus revascularization therapy.

Cardiac Imaging for Risk Stratification in Diabetes

“…As a result, a highresolution image is acquired in 50Ϫ100 milliseconds. In the general population, the sensitivity and specificity to detect CAD are 87 and 91%, respectively (10 studies, 583 patients) (30). No specific studies in patients with diabetes are available.…”

Middle Cerebral Artery Occlusion Associated With Acute Myocardial Infarction in the Perioperative Period-Case Report-

“…6) Noninvasive coronary angiography, such as MR angiography and multi-row detector spiral CT, is a rapidly developing technique and provides a safer, less invasive method to determine the need for medical versus revascularization therapy. 1) The present case suggests the necessity for coronary angiography in a patient with major intracranial artery occlusive disease such as MCA occlusion or stenosis, preferably by MR angiography or multirow detector spiral CT. If stenosis is detected in the coronary artery, medical or revascularization therapy for coronary artery stenosis should be performed, followed by brain surgery.…”

Noninvasive imaging modalities to visualize atherosclerotic plaques

“…There are two different types of available CT. Electron beam computed tomography (EBCT) is the nonmechanical movement of the X-ray source and multidetector-row computed tomography (MDCT) is performed by the motion of the X-ray source and table, combined with multiple detection to acquire the data in spiral or helical fashion (11). Accumulating evidence suggests the ability of EBCT/MDCT to evaluate coronary artery calcification, atherosclerosis and fractional flow reserve (FFR).…”
