A comparison study between CT angiography with 64-multislice spiral computed tomography and selective X-ray coronary angiography.

The aim of this study was to evaluate the diagnostic value of 64-multislice spiral computed tomography (64-MSCT) for coronary stenosis compared with selective X-ray coronary angiography (SCA). Patients with chest pain, chest tightness or coronary stenosis received SCA and they acted as the controls. The sensitivity and accuracy of 64-MSCT were analyzed as compared with SCA. Images from 64-MSCT were obtained for 95 patients. For the diagnosis of myocardial bridge, 64-MSCT coronary CT angiography (CTA) is superior to SCA. In cases of mild coronary stenosis, combined with clinical symptoms, patients may choose to receive conservative treatment instead of SCA. However, cases of moderate coronary stenosis should receive SCA to determine the diagnosis. In conclusion, no difference was observed between 64-MSCT coronary CTA and SCA in their ability to exclude true negative diagnoses and diagnosing true positives of coronary disease. The 64-MSCT coronary CTA method produces improved image quality for diagnosis of coronary stenosis and is a non-invasive, reliable and effective method for the diagnosis of the severity of coronary stenosis.
