目的 :分析腹盆部空腔脏器实体癌肿术后肿物的螺旋CT早期增强表现 ,及评价SCT对其良恶性鉴别诊断的价值。方法 :5 4例腹盆部空腔脏器实体癌肿病人术后 3～ 46个月随诊时发现腹盆部肿物 ,即行SCT平扫与增强扫描 ,并测肿物的CT强化值。结果 :5 4例病人 ,SCT共发现 60个病灶。SCT增强早期 ,2 2个纤维化病灶强化值为 0～ 8HU ,3 8个复发癌与炎性病变强化值为 13～ 46HU。SCT对纤维化病灶能准确判断 ,对复发癌判断的准确性 88.3 % ,敏感性 10 0 % ,特异性75 .9%。结论 :SCT增强早期对腹盆部空腔脏器实体癌肿术后肿物的鉴别提供了有价值的信息 ,有助于复发癌与纤维化病变的鉴别诊断。
OBJECTIVE: To analyze the early enhancement of spiral CT of solid tumors in abdominal cavity organs and to evaluate the value of SCT in differential diagnosis of benign and malignant tumors. Methods: Forty-four patients with solid tumors of the abdominal cavity and hollow organs were observed for abdominal metastasis from 3 to 46 months after operation. The CT scan of the SCT was performed and the CT value of the tumor was measured. Results: A total of 60 lesions were found in 54 SCT patients. In the early stage of SCT enhancement, the enhancement value of 2 2 fibrosis lesions was 0 ~ 8HU, and the enhanced value of 38 recurrent tumors and inflammatory lesions was 13 ~ 46HU. SCT on fibrosis lesions can accurately determine the accuracy of the diagnosis of recurrent cancer 88.3%, sensitivity 10%, specificity 75.9%. CONCLUSIONS: Early SCT enhancement provides valuable information for the differential diagnosis of solid tumors of abdominal cavity organs after abdominal cancer surgery, and is helpful for the differential diagnosis of recurrent cancer and fibrotic lesions.
