Anatomy of the Heart at Multidetector CT: What the Radiologist Needs to Know¹

¹ From the Department of Radiology, New York University Medical Center, 560 First Ave, New York, NY 10016. Received November 30, 2006; revision requested March 12, 2007 and received April 20; accepted May 9.

Continued improvements in multidetector computed tomographic (CT) scanners have made cardiac CT an important clinical tool that is revolutionizing cardiac imaging. Multidetector CT with submillimeter collimation and gantry rotation times under 0.5 seconds allows the acquisition of studies with high temporal resolution and isotropic voxels. The volumetric data set that is generated can be analyzed with a depth previously not possible, requiring a solid understanding of the cardiac anatomy and its appearance on CT scans and postprocessed images.
