Journal ArticleDOI
Detection of Coronary Artery Stenoses by Contrast-Enhanced, Retrospectively Electrocardiographically-Gated, Multislice Spiral Computed Tomography
Stephan Achenbach,T. Giesler,Dieter Ropers,Stefan Ulzheimer,Hans Derlien,Christoph Schulte,Evelyn Wenkel,Werner Moshage,Werner Bautz,Werner G. Daniel,Willi A. Kalender,Ulrich Baum +11 more
TL;DR: MSCT with retrospective ECG gating permits the detection of coronary artery stenoses with high accuracy if image quality is sufficient, but its clinical use may presently be limited due to degraded image quality in a substantial number of cases.
Journal ArticleDOI
Noninvasive coronary angiography by retrospectively ECG-gated multislice spiral CT.
Stephan Achenbach,Stefan Ulzheimer,Ulrich Baum,Marc Kachelrieß,Dieter Ropers,T. Giesler,Werner Bautz,Werner G. Daniel,Willi A. Kalender,Werner Moshage +9 more
TL;DR: This investigation investigated the applicability and image quality of contrast-enhanced coronary artery visualization by multislice spiral CT using retrospective ECG gating to determine the visualized length of the coronary arteries, the contrast-to-noise ratio, and the correlation of...
Journal ArticleDOI
Noninvasive Visualization of Coronary Arteries Using Contrast-Enhanced Multidetector CT: Influence of Heart Rate on Image Quality and Stenosis Detection
T. Giesler,Ulrich Baum,Dieter Ropers,Stefan Ulzheimer,Evelyn Wenkel,Maria Mennicke,Werner Bautz,Willi A. Kalender,Werner G. Daniel,Stephan Achenbach +9 more
TL;DR: The usefulness of MDCT as an aid in accurately evaluating stenoses decreases as a patient's heart rate increases, and the sensitivity for stenosis detection decreased as the heart rate increased.
Journal ArticleDOI
Investigation of aortocoronary artery bypass grafts by multislice spiral computed tomography with electrocardiographic-gated image reconstruction.
Dieter Ropers,Stefan Ulzheimer,Evelyn Wenkel,Ulrich Baum,T. Giesler,Hans Derlien,Werner Moshage,Werner Bautz,Werner G. Daniel,Willi A. Kalender,Stephan Achenbach +10 more
TL;DR: Clinical and angiographic outcome after angiographically-guided stent placement in small coronary vessels following coronary stenting of small vessels is studied.
Journal ArticleDOI
Comparison of image quality in contrast-enhanced coronary-artery visualization by electron beam tomography and retrospectively electrocardiogram-gated multislice spiral computed tomography.
Stephan Achenbach,T. Giesler,Dieter Ropers,Stefan Ulzheimer,Katharina Anders,Evelyn Wenkel,Karsten Pohle,Marc Kachelriess,Hans Derlien,Willi A. Kalender,Werner G. Daniel,Werner Bautz,Ulrich Baum +12 more
TL;DR: EBT and MSCT permit reliable coronary artery visualization and measurement of vessel diameters and for the used scan protocol, MSCT images had a lower CNR and were more frequently affected by motion.
