摘　　要：目的:探讨多排螺旋CT在诊断卵巢癌腹膜转移中的价值。方法:对30例经手术病理证实的卵巢癌伴腹膜转移患者的多排螺旋CT资料进行回顾性分析。结果:30例患者中,手术发现腹膜转移部位为右半膈10例,右半结肠旁沟18例,胃小弯侧1例,阑尾1例,大网膜24例,盆腔(包括子宫直肠陷凹和子宫阔韧带)20例。CT发现右半膈4例,右半结肠旁沟14例,大网膜22例,盆腔(包括子宫直肠陷凹和子宫阔韧带)18例,胃小弯侧和阑尾病灶未发现。右半膈、右半结肠旁沟、大网膜和盆腔的病灶发现阳性率分别为40%(4/10),78%(14/18),92%(22/24),90%(18/20)。结论:结合多排螺旋CT可薄层扫描和多平面重组的优势,可提高卵巢恶性肿瘤腹膜转移诊断的阳性率,为下一步治疗提供有力帮助。Objective： To evaluate the clinical effectiveness of multi-detector-row computed tomography scanning in the detection of peritoneal metastases from ovarian cancers. Methods：CT findings of 30 pathologically proven ovarian cancer patients with peritoneal metastases were retrospectively studied. Results： The sites of peritoneal metastases were surgically proved as follows：right hemi-diaphragm in 10 cases, right paracolonic groove in 18 cases,lesser curvature of the stomach in 1 case,cecal appendix in 1 case,major omentum in 22 cases and pelvic cavity in 18 cases. The metastatic cases positively detected by CT included 4 cases with right diaphragm metasases, 14 cases with right paracolonic groove metastases, 22 cases with major omentum metastases and 18 cases with pelvic metastases. The metastatic lesions involving the minor curvature of the stomach and appendix were not detected. The detection rates of the metastatic deposits from ovarian malignancies involving the right diaphragm, the right paracolonic groove, the major omentum and the pelvic cavity were 40% （4/10）,78% （14/18） ,92% （22/24）and 90% （18/20） respectively. Conclusion：In combination with the potentials of multi-detector row CT,such as thin-sliced and muhiplanar image reconstruction techniques, the CT detection rate and diagnosis of peritoneal metastases from ovarian malignancies are improved and it is obviously beneficial to further treatments for the patients.
