Artifacts in ECG-Synchronized MDCT Coronary Angiography

¹ All authors: Department of Radiology, C2S, Leiden University Medical Center, Albinusdreef 2, 2333 ZA, Leiden, The Netherlands.

OBJECTIVE. In MDCT coronary angiography, image artifacts are the major cause of false-positive and false-negative interpretations regarding the presence of coronary artery stenoses. Hence, it is important that observers reporting these investigations are aware of the potential presence of image artifacts and that these artifacts are recognized.

CONCLUSION. The article explores the technical causes for various artifacts in MDCT coronary angiography imaging and clinical examples are given.

Keywords: artifacts • cardiac imaging • computed tomography • coronary angiography • CT • diagnostic imaging
