【摘要】目的:探讨卵巢癌的CT表现,提高卵巢癌的诊断水平。方法:分析近年来在我院做CT扫描的120例卵巢癌患者的CT表现,并与手术病理结果进行对照分析。结果:卵巢癌主要表现为囊实性或实性肿块,以实性成分为主,增强扫描明显强化,CT值平均增高20Hu,单侧性49例,%,双侧性71例,%;来自于上皮的肿瘤88例,%,来自于间质细胞肿瘤及生殖细胞肿瘤各8例,%;其他16例,%。结论:常规及螺旋CT扫描能显示卵巢癌的CT特征,对提高卵巢癌的诊断水平有帮助。

【ABSTRACT】 Objective: To investigate the function of CT in diagnosing ovary cancer, and improve the diagnostic level for ovary cancer. Methods: Analyze the CT results for 120 cases with ovary cancer who have conducted CT scanning in our hospital within recent years,pared with pathological results of the operations. Results: Ovary cancer is mainly showed as cysticsolid or solid tumor and solid content accounts for the majority. these phenomenon are more apparent after strengthened scanning. The average CT data increases 20Hu, 49cases(%) are unilateral tumor and 71cases(%) are bilateral tumor; 88 cases (%)are epithelial tumor, 8 case of interstitial cell tumor and 8 case of germ cell tumor, each accounts for %; 16 cases are othiers,accounting for %. Conclusion: CT and Helical CT scanning can show the CTfeatures for ovary cancer, and are helpful in improving the diagnostic level for ovary cancer.

卵巢恶性肿瘤是常见的女性生殖系统恶性肿瘤,卵巢组织来源复杂,包括上皮性、间质性、生殖细胞来源,%,其中浆液性囊腺癌占上皮性来源63%[1]。CT具有良好的分辩率,对观察病变组织的密度非常准确,特别是螺旋CT的容积扫描,可以任意角度和层厚进行重建,对卵巢病变的定性诊断具有较大的优势[2]。
本文回顾性分析120例经手术证实的卵巢恶性肿瘤,进一步探讨CT对卵巢恶性肿瘤的诊断、鉴别诊断以及对预后的评估。
1 资料与方法
~。年龄16~70岁,;%;×16cm×12cm,××。其中腺癌72例,低分化浆液性囊腺癌18例,浆液性乳头状囊腺癌16例,透明细胞癌4例,纤维肉瘤10例。
方法使用Siemens Somatom CR型CT及Toshiba Asteion VR螺旋CT扫描。于检查前一天晚上,%~%的泛影葡胺800~1000ml以充盈小肠及结肠;检查当天空腹,晨起后清洁灌肠并嘱患者憋尿,如保留导尿者操作更简便。~%的泛影葡胺300~500ml,充盈胃及空肠;~%的泛影葡胺300~500ml,充盈直肠及乙状结肠;患者自觉有尿意后,保留导尿者经导尿管注入生理盐水300~400ml,充盈膀
