MSCT诊断腔外型胃肠道间质瘤的CT表现
Clinical Value of MSCT Diagnosis in Extraluminal Type Gastrointestinal Stromal Tumor
摘要
Abstract
Objective To investigate the imaging findings and diagnostic value of multi-slice spiral CT (MSCT) in the extraluminal gastrointestinal stromal tumor (GIST). Methods MSCT findings combined with three-dimensional (3D) reconstruction images of 50 patients with pathological y and surgical y proved extraluminal GIST were retrospectively analyzed. Al plain, dual-phase or Triple-phase contrast enhanced MSCT were performed preoperatively. Results The 50 cases of GIST, al extraluminal ,15 tumors were found in stomach, 15 in smal intestine (6 in duodenum, 6 in jejunum and 3 in ileum), 3 in sigmoid colon, 3 in rectum, 3 in omentum majus, 3 in mesentery, 5 in retroperitoneal, 4 in pelvic and 2 in bladder. 12 tumors were solid homogeneity mass. 38 were heterogeneous-solid tumors. 30 tumors were solid and necrosis. 24 were solid mass with hemor hage. 18 were complicated with hemor hage, necrosis or cystic degeneration. 3 were solid mass with calcification and 6 were pneumatosis. CT showed 40 cases with clear boundary, 19 cases of fate leaf and 3 cases of metastsis (including 4 cases of lymph node metastasis and 3 cases of recur ence). Tumor were mild to intense enhancement on contrast enhanced scan. Al lesions show marked enhancement at arterial phase were durative enhancement in venous and delayed phase.The accuracy for location and quality of MSCT were 94% (47/50) and 82%(41/50). Conclusion Multi-phase enhancement scan of MSCT and 3D-image reconstruction techniques have great value in diagnosing extraluminal gastrointestinal stromal tumors which can show the situation, shape, size, density and artery of the tumor clearly.关键词
