目的探讨多层螺旋CT(MSCT)对原发性腹膜后肿瘤的诊断价值。方法分析27例资料完整的原发性腹膜后肿瘤患者MSCT平扫加三期强化扫描的影像资料。结果肿瘤术前MSCT检出率100%(27/27);术前定位准确率92.59%(25/27);术前良、恶性判断准确率85.15%(23/27);术前病理组织类型判断准确率为29.63%(8/27);能清晰提示肿瘤与周围脏器、大血管及输尿管之间的关系。结论 MSCT能对原发性腹膜后肿瘤的定位、定性诊断提供可靠的影像学依据。
Objective To investigate the diagnostic value of multislice spiral CT (MSCT) in primary retroperitoneal tumor. Methods Imaging data of 27 cases of primary retroperitoneal tumor with MSCT and three stages of intensive scanning were analyzed. Results The preoperative MSCT detection rate was 100% (27/27). The preoperative localization accuracy was 92.59% (25/27). The accuracy of preoperative benign and malignant judgment was 85.15% (23/27). The preoperative pathological type The accuracy of the judgment was 29.63% (8/27), which could clearly indicate the relationship between the tumor and the surrounding organs, blood vessels and ureters. Conclusion MSCT can provide a reliable imaging basis for the localization and qualitative diagnosis of primary retroperitoneal tumors.
