目的 :评估B超、CT、MRI、血管造影对盆部腹膜外软组织肿瘤的诊断价值。材料和方法 :分析 88例盆部腹膜外软组织肿瘤影像表现 ,并与手术病理结果对照。结果 :B超、CT、MRI对肿瘤的检出率均为 10 0 %。恶性者 86.7%B超、87.5 %CT显示为囊实性或实性 ,93 .3 %CT显示密度不均。B超显示输尿管扩张、CT显示髂血管受累的敏感性最高 ,分别为 88.9%、75 %。MRI显示盆部血管、神经、骨骼受累的敏感性分别 10 0 %、10 0 %、80 %。结论 :综合分析影像资料并紧密结合临床 ,是有效诊治盆部腹膜外软组织肿瘤的重要手段。
Objective: To evaluate the value of ultrasonography, CT, MRI and angiography in the diagnosis of pelvic extraperitoneal soft tissue tumors. Materials and Methods: 88 cases of pelvic extraperitoneal soft tissue tumor imaging performance and surgical pathology results were compared. Results: The detection rates of B-ultrasound, CT and MRI were all 10%. Malignant 86.7% B ultrasound, 87.5% CT showed cystic solid or solid, 93.3% CT showed uneven density. B ultrasound showed ureteral dilation, CT showed the highest sensitivity of iliac vascular involvement, respectively, 88.9%, 75%. MRI showed pelvic vessels, nerves, and skeletal involvement sensitivity of 100%, 100%, 80% respectively. Conclusion: The comprehensive analysis of the imaging data and the close clinical practice are important measures to diagnose and treat the extraperitoneal soft tissue tumors in the pelvis.
