Multislice-computertomographie des herzens (MSCT)

High spatial resolution and considerable reduction of gantry times promoted modern 16- to 64-multislice CT-scanning back into the focus of cardiological interest. However, morphological and functional imaging of cordial structures do not play a primary role in this matter due to other competitive practicable imaging modalities. Rather the possibilities of non-invasive coronary angiography appeared with multislice-CT. Sensitivity for detection of significant stenoses lies between 80% ond 95% in several clinical studies with preselected patients and negative predictive value to exclude coronary heart disease approaches 100%. Despite excellent digestibility of non-ionic contrast media, low radiation exposure, and vanquishing of arrhythmic hindrance by means of the fastest scanners, inherent disadvantage of the method involves the lack of interventionol possibilities. For that reason Q-angiography will not be able to relieve invasive coronary angiography in the near future. However exclusion of relevant coronary heart disease in symptomatic patients with low pretest likelihood is already a proven indication, when actual technology and investigational proficiency are given.
