Multi slice CT (MSCT) scanners are becoming popular as a non-invasive imaging modality for screening coronary artery disease. The era of MSCT started with 4 slice scanners and progressed to the 64 slice MSCT which is commonly used now. 256 slice and 320 slice CT scanners are also being evaluated for clinical use. One of [...]

Cardiac CT scan image at PA bifurcation Cardiac CT scan image at the level of the bifurcation of the main pulmonary artery (MPA) into right pulmonary artery (RPA) and left pulmonary artery (LPA). Ascending aorta (AAo) and descending aorta (DAo) are seen as two contrast filled circles (cross section) anteriorly and posteriorly. Descending aorta is [...]

Cardiac CT angiograms are increasing in popularity as a non-invasive screening tool for detecting significant coronary artery disease. The angiograms are reconstructions from 64 or more slice CT scans following intravenous injection of radiocontrast dye. As of now it cannot replace conventional coronary angiograms for assessing the detailed coronary anatomy. LAD, LCX and Left main [...]

Click on the image for a larger view The saccular aortic aneurysm of the proximal descending thoracic aorta is visible within the cardiac silhouette just below the aortic knuckle on the left border. It is partly overlapped by the main pulmonary artery shadow. The cardiac size is normal and so is the asecending aorta. CT [...]
