Multi-Detector Computed Tomography for Assessing the Left Ventricular Function, Perfusion and Viability

다국어 초록 (Multilingual Abstract)

MDCT has recently been used as a diagnostic tool to evaluate coronary artery stenosis and to detect coronary arteryanomalies. The accuracy of MDCT has improved the assessment of stenosis as the number of detectors has increased.In addition to its excellent role in evaluating coronary artery stenosis, MDCT can provide information regardingthe left ventricular function without having to perform additional scanning, and the myocardial viability of theleft ventricle can be assessed on a delayed scan. MDCT has several disadvantages such as the amount of radiationexposure and the use of an iodine contrast medium, which might cause an adverse reaction, when combined withthe reconstruction of the systolic and diastolic phases and the delayed scan. Yet MDCT may provide the opportunityto evaluate the coronary anatomy, the left ventricular function and the tissue characterization in one singleimaging session that lasts less than 15 minutes.
