Abstract：Objective: To study the application value of 64 row spiral CT angiography in arterial disease. Materials and Methods: 64 row spiral CT angiography in 310 cases were analyzed including intracranial vascular CTA 36 cases, carotid artery 70 cases, thoraco-abdominal vessels 175 cases, renal artery 28 cases, lower extremity1case, dose of contrast medium used was 0.8～1.5ml/kg, general dosage 60～80ml, the rate of injection was 4.0～5ml, two methods of scan delay time were applied: SURE START bolus tracking and calculating time data. Reconstruction was done with Vitrea 2 workstation. Results: 64 rows spiral CT angiography in 310 cases, images and the anatomy display detail, and the focal display precise. Conclusion: 64 row spiral CT has improved technology on two sides: high spatial resolution(submillimetre) and high time resolution, more higher speed scanning, more larger region scanning, isotropic scanning, CT angiography is simple and quick. 64 row spiral CT has the advantages than previous multi-slice CT (MSCT) in the application of arterial disease.
