Abstract
Our data shows the regional coronary artery calcium scores (lesion CAC) on multidetector computed tomography (MDCT) and the cross-section imaging on MDCT angiography (CTA) in the target lesion of the patients with stable angina pectoris who were scheduled for percutaneous coronary intervention (PCI). CAC and CTA data were measured using a 128-slice scanner (Somatom Definition AS+; Siemens Medical Solutions, Forchheim, Germany) before PCI. CAC was measured in a non-contrast-enhanced scan and was quantified using the Calcium Score module of SYNAPSE VINCENT software (Fujifilm Co. Tokyo, Japan) and expressed in Agatston units. CTA were then continued with a contrast-enhanced ECG gating to measure the severity of the calcified plaque condition. We present that both CAC and CTA data are used as a benchmark to consider the addition of rotational atherectomy during PCI to severely calcified plaque lesions.

Summary
The data of CAC and CTA on MDCT were obtained in patients with stable angina pectoris who were scheduled for first PCI. (1) The straight curved planar reconstructions (CPR) image, and: the cross-section multiplanar reconstruction (MPR) image at each point of X, and A to E, (2) the stretch CPR image, (3) the angiographic view image by the analytical virtual 3-dimensional model. The severity of coronary artery stenosis and the length of one coronary lesion with Z75% luminal diameter stenosis were measured by the straight CPR image and the cross-section MPR image. The severity of the calcified plaque condition was assessed using the number of quadrants involving calcium on an arterial cross-section (MPR)
