CT is a correct process for assessing cardiac constitution and serve as, yet advances in computing energy and scanning expertise have ended in elevated attractiveness. it's valuable in comparing the myocardium, coronary arteries, pulmonary veins, thoracic aorta, pericardium, and cardiac lots; due to this and the rate at which scans will be played, CT is much more appealing as an economical and necessary a part of sufferer assessment. This booklet collates the entire present wisdom of cardiac CT and offers it in a clinically appropriate and sensible layout applicable for either cardiologists and radiologists. the photographs were provided via an skilled set of contributing authors and signify the complete spectrum of cardiac CT. As expanding numbers have entry to cardiac CT scanners, this booklet presents the entire appropriate info in this modality. A CD-ROM is incorporated containing a lot of cardiac CT photographs and movies, supplying the reader with a dynamic primer in cardiac CT diagnosis.

The use of low osmolar non-ionic contrast media signiﬁcantly reduces adverse reactions to contrast media . Optimal enhancement is very important for improvement of image quality. The optimal enhancement depends on the contrast media dose and injection rate. The dose of contrast media is dependent on multiple factors, such as patient size, scan time, and desired enhancement level (CT 22 Cardiac CT Imaging: Diagnosis of Cardiovascular Disease HU). The total dose for a procedure typically should not exceed 200 mL of high concentration contrast media for coronary arteriography and left ventriculography with EBT [14,31,32].
