Application of 16-slice Spiral CT Angiography in Diagnosis of Upper Extremity Arterial Disease

Object To study the value 16-slice Spiral CT angiography in the diagnosis of upper extremity arterial disease. Material and methods Thirteen suspected patients with blocked disease of super extremity arteries were examined with CTA,all performed Volume Rendering(VR)、Maximum Intensity Projection(MIP)、Multiplana(rMPR)。 Results Constrictions were found in subclavian arteries of 9 patients,occlusion was found in the left brachial artery of one patient and aneurysm was found in the right axillary artery of one patient.8 cases were proved by DSA. Conclusion 16-slice Spiral CT Angiography in upper extremity is an accurate and non-invasive angiographic technique.
