Summary: Multi-row-detector CT angiography uses synchronized raw data acquisition with ECG curve. Only
a part of data set in diastolic phase is used for reconstruction of images with temporal resolution
up to 105 ms. The axial images and 3D-reconstructions of coronary vessels are evaluated. The most
important disadvantage is a relativelly low temporal resolution, CTA couldn’t be used for patients
with the heart rate over 85 bpm and for patients with arythmia. Fine branches of coronary tree on
lateral and lower wall isn’t displayed very well in all patients. Although this unique method has
a limitation in comparison to catheterization coronarography, it is the first step to noninvasive
coronary imaging. Authors report about a group of 30 patients with different coronary vessel
pathology who underwent examination on sixteen-row-detector equipment Somatom Sensation 16
(Siemens, Forchheim, Germany) using a rotation period of 420 ms.
