[Initial experiences with multi-slice detector spiral CT in diagnosis of arteriosclerosis of coronary vessels]. Der Radiologe Becker, C. R., Knez, A., Leber, A., Hong, C., Treede, H., Wildhirt, S., Ohnesorge, B., Flohr, T., Schoepf, U. J., Reiser, M. F. 2000; 40 (2): 118-122

Abstract

Multi-row-detector-spiral-CT (MSCT) allows for 250 ms effective exposure time. The purpose of this study was to demonstrate the possibilities and limitations of this CT technology for non enhanced and contrast enhanced investigation of the coronary arteries.Investigation of the coronary arteries without contrast medium for quantification of coronary calcifications was performed in an obese patient (140 kg) with MSCT and electron beam CT (EBCT). In 56 patients contrast enhanced CT angiography of the coronary arteries was performed to determine image quality depending on the heart rate.In the obese patient superior image quality could be achieved with MSCT allowing for reliable quantification of coronary calcifications. With MSCT angiography of the coronary arteries good image quality was achieved in patients with a heart rate of 59 +/- 8 beats per minute.Even if there are limitations in patients with higher heart rates with an effective exposure time of 250 ms MSCT has clear advantage of image quality in the assessment of non enhanced and contrast enhanced coronary arteries.
