Diagnostic Value of Multidetector Computer Tomography Coronary Angiography in Detection of Coronary Artery Stenosis

Abstract

Invasive coronary angiography (ICA) is the accepted reference standard for the assessment of coronary artery stenosis because of its unprecedented temporal and spatial resolution and ability to perform therapeutic interventions in the same session [1]. The inconvenience for the patient and economic deliberations have strengthened the search for a non-invasive alternative, current multi-slice computed tomography (MSCT) scanners provide promising results in the assessment coronary artery disease (CAD), but some segments are not evaluative because of motion artifacts or sever vessel wall calcification [2]. To become a clinically accepted tool for the examination of patients with suspected CAD, the main requisite for CT coronary angiography includes the complete visualization of all therapeutic relevant coronary arteries without excluding segments [3]. The recently developed 64 slice CT scanner generation of provide 0.4 mm nearly isotropic voxels in a rotation time of 0.37 sec, thus increasing temporal and spatial resolution when compared with previews CT scanner types [5, 6].
