目的:探讨螺旋CT扫描技术在女性盆腔病变诊断价值。方法:分析57例女性盆腔病变CT表现,并与手术病理结果对照。结果:病变检出率100%,手术符合率88%。卵巢癌与囊腺瘤的鉴别要点是:实性组织在肿物中所占的比例和软组织结节形态和在动、静脉期的强化特点。动脉期“双环征”及静脉期、延迟扫描持续强化是卵巢脓肿的特征。子宫内膜癌及绒癌在动脉期与正常子宫平滑肌比较有相反的CT特征。直肠左右明显移位是后腹膜病变定位可靠的CT征象。结论:螺旋CT双期扫描能显示各种女性盆腔病变更多CT特征,对提高女性盆腔病变术前诊断有意义,经验不足是造成误诊主要原因。
Objective: To investigate the value of spiral CT scan in the diagnosis of pelvic lesions in women. Methods: The CT findings of 57 cases of female pelvic lesions were analyzed and compared with the surgical pathology results. Results: The detection rate of lesions was 100% and the coincidence rate was 88%. Ovarian cancer and cystadenoma identification points are: solid tissue in the proportion of tumors and soft tissue nodules in the shape and dynamic and venous phase of the enhanced features. Arterial “double ring sign” and venous phase, delayed scan continued enhancement is the characteristics of ovarian abscess. Endometrial cancer and choriocarcinoma in the arterial phase with normal uterine smooth muscle contrasted CT features. Apparent shift of the rectum is a reliable CT sign of retroperitoneal lesions. Conclusion: The double-phase spiral CT scan can show more CT features of various pelvic lesions, which is significant to improve the preoperative diagnosis of pelvic lesions in women. The lack of experience is the main reason of misdiagnosis.
