“…However, no consensus has yet been reached on the boundary between normal variant and anomaly. A number of classification systems of the coronary artery anomalies have been suggested (2,5,(10)(11)(12). According to these systems, anomalies of the coronary arteries are generally divided into anomalies of origin and course, anomalies of intrinsic coronary arterial anatomy, and anomalies of termination.…”

“…Despite its common use, alternative methods of visualizing the coronary arterial system are desired; in addition to being invasive, CCA has disadvantages in detecting coronary artery anomalies because of the limited number of 2D projection images obtained during catheterization and because of the absence of soft tissue information. MSCT angiography is considered a first-line imaging modality in detecting coronary artery anomalies (5)(6)(7)(8).…”

The small dimensions and rapid movement of coronary arteries have made their evaluation with computed tomography (CT) challenging. However, because of the dramatic development of multislice CT (MSCT) technology in the last decade, coronary CT angiography (CTA) has become an increasingly important noninvasive modality in the diagnosis of coronary artery diseases. High temporal and spatial resolution capabilities of MSCT scanners enable detailed 3D visualization of complex coronary artery anatomy without motion artifact.To be able to interpret the coronary CTA correctly, radiologists should be familiar with normal anatomy, anatomic variants, and anomalies of the coronary arteries and their cross-sectional appearances. In this study, we aimed to identify the 64-slice CTA appearance of the anatomic variations and anomalies of the coronary arteries and determine their incidence in a population of 700 patients. Materials and methodsCT data of 700 patients (405 males, 295 females; age range, 17-85 years) who underwent 64-slice coronary CTA in our institution were retrospectively reviewed to identify the coronary anatomy and determine anatomic variants and anomalies. Patients were referred for coronary CTA because of known or suspected coronary artery disease (CAD). The institutional review board approved the study. CT scanAll CT examinations were performed by a 64-slice CT scanner (Aquillon 64, Toshiba Medical Systems, Tochigi, Japan) with retrospective ECG gating (scan protocol is given in Table 1). Patients with a heart rate greater than 75 beats/min were premedicated with an oral dose of 40 mg propronalol one hour before the scan. Sublingual nitroglycerine was delivered to the patient just before the scan. For venous access, an upper extremity vein (antecubital vein of the right arm) and a 20-gauge IV cannula was used. A total of 80-85 mL of contrast media with high iodine concentration (≥350 mg/mL) was injected with a flow rate of 5 mL/s, followed by a 20 mL saline chaser. The scan timing was determined with automated bolus tracking technique by placing the region of interest over the proximal descending aorta and setting the trigger threshold to 180 HU.Raw spiral CT data were reconstructed in various phases of the cardiac cycle to obtain images with the highest quality (without motion artifact). Reconstruction performed at 75% of R-R interval was found to be optimal for image analysis in most patients. Image analysisImages reconstructed at the optimal phase were transferred to another workstation (Vitrea 2 workstation, Vital Images Inc., Plymouth, Minne- CARDIOVASCULAR IMAGING PURPOSETo retrospectively review the 64-slice computed tomography (CT) appearance of coronary artery anatomic variants and anomalies and determine their incidence in 700 patients.

“…Therefore, we did not select these imaging methods. Previous reports assessing the utility of CT for identifying coronary arteries have suggested the use of coronary CT. [8][9][10][11] In the present study, we used aortic CT, which takes images of the patient from the neck to the groin. Given that the chest range was gated, aortic CT can evaluate the positions of coronary artery orifices accurately.…”
