MEASUREMENT OF CARDIAC-OUTPUT BY COMPUTED TRANSMISSION TOMOGRAPHY INVESTIGATIVE RADIOLOGY Herfkens, R. J., Axel, L., Lipton, M. J., Napel, S., BERNINGER, W., REDINGTON, R. 1982; 17 (6): 550-553

Abstract

The capability of computed tomography (CT) scanning to measure cardiac output was explored using ten anesthetized dogs, and the results were compared with those obtained by thermodilution. Dynamic CT scans were performed at the level of the aortic root while small peripheral intravenous boluses of contrast medium were injected. Time/density curves were generated using a gamma variate fitting program. These were used to estimate cardiac output by applying indicator dilution principles. CT results correlated favorably (r = 0.86) with those of thermodilution. This feasibility study indicates the utility of CT for obtaining physiologic measurements of cardiac function and should encourage further studies to develop the potential of CT for cardiovascular diagnostic purposes.
