CT和B超对卵巢肿瘤定性的诊断价值比较

目的探讨卵巢肿瘤的CT、B超表现,并就两种检查方法对卵巢肿瘤定性诊断作对照分析。方法对78例(102个病灶)经病理证实的卵巢肿块的临床及影像学资料作回顾性分析。经CT检查55例,经B超检查62例,同时经CT和B超检查者39例,间隔时间为0～3d。结果CT、B超对卵巢良、恶性肿瘤判断的敏感性、特异性和准确性分别为94.7%对89.9%,87.5%对81%,93.2%对88%,经χ2检验无显著差异(P>0.05)。但CT对卵巢肿瘤腹腔、腹膜种植、淋巴结肿大等有助卵巢肿瘤定性诊断及临床分期的征象检出率均高于B超,χ2检验有显著差异(P<0.05)。结论CT与B超对卵巢肿瘤具有重要诊断价值,CT在卵巢肿瘤定性诊断及辅助恶性肿瘤临床分期方面优于B超。

A comparative study of CT and ultrasound in the qualitative diagnosis of ovarian neoplasms

Objective To study the CT and ultrasonic manifestations of ovarian neoplasms, and compare those imaging modalities in the qualitative diagnosis of ovarian neoplasms. Methods Clinical material and images of 78 cases of ovarian neoplasms, proved by histopathology, were retrospectively reviewed. In this study, 55 patients were evaluated by CT and 62 patients were examined by ultrasound. Both CT scan and ultrasound were performed in 39 patients with intervals of 0-3 days. Results The sensitivity , specificity and accuracy of CT and ultrasound in the evaluation of ovarian neoplasms were 94.7%vs 89.9%, 87.5%vs 81%, 93.2%vs 88%, respectively. No significant difference were found between those two modalities by chi-square test (P >0.05). While the statistical study revealed CT was superior to the ultrasound (P< 0.05) in assessing the signs that helps the qualitative diagnosis and staging of ovarian neoplasms. Conclusion CT and ultrasound are valuable modalities in the diagnosis of ovarian neoplasms. CT is superior to the ultrasound in qualitative diagnosis and staging of ovarian tumors.
