Application of Dual Source CT on Artery Injury in Extremities / 医疗卫生装备

ABSTRACT

Objective To assess the clinical application value and advantages of DSCT Angiography on artery injury in Extremities. Methods Seven suspected patients with artery injury in extremities underwent DSCT Angiography, including three cases on artery injury of upper extremity and four cases on artery injury of lower extremity. All the seven patients were performed with DSCT Angiography after the operation. The data of thin slice cross section were reconstructed by MPR, MIP and VR, employing Somatom Definition, German. Contrast-concentration was 350 or 370mg i/ml, total amount was 80-100ml and injection rates was 4.0 ml/s. Results All the images of angiography displayed many clear blood vessels and smooth vessels verge, contrasting with surrounding issues well. They also displayed no ladder artifact or truncation artifact. The image quality was good enough to meet the requirements of clinical diagnosis. Meanwhile the coincidence between preoperative diagnosis and postoperative diagnosis was 100%. Conclusion To suspected patients with artery injury in extremities, DSCT Angiography may be the first choice. Three-dimensional reconstruction angiographys by means of different reconstruction techniques are very helpful in diagnosing and formulating treatment perscription.
