摘　　要：目的探讨在卵巢癌淋巴结转移诊断中,腹盆腔增强CT与盆腔MRI平扫的诊断性能对比。方法选取卵巢癌患者46例作为研究对象,安排接受腹盆腔增强CT与盆腔MRI平扫,以病理结果为参照计算两种方法的灵敏度、特异度、阳性预测值以及阴性预测值。结果CT扫描检查结果显示,腹盆腔增强CT在卵巢癌盆腔淋巴结转移诊断中,灵敏度为45.00%,特异度为73.08%;盆腔MRI平扫在卵巢癌盆腔淋巴结转移诊断中,灵敏度为60.00%,特异度为80.77%;腹盆腔增强CT联合盆腔MRI平扫在卵巢癌盆腔淋巴结转移诊断中,灵敏度为85.00%,特异度为92.31%。结论在卵巢癌淋巴结转移诊断中,相较于腹盆腔增强CT,盆腔MRI具有较高的诊断灵敏度和特异度,但两者联合运用取得的诊断效能更高。Objective To compare the diagnostic performance of abdominal and pelvic enhanced CT and pelvic MRI plain scan in the diagnosis of lymph node metastasis in ovarian cancer.Methods 46 patients with ovarian cancer were selected as the study subjects,and abdominal and pelvic enhanced CT and pelvic MRI plain scans were arranged.The sensitivity,specificity,positive predictive value,and negative predictive value of the two methods were calculated based on pathological results.Results The CT scan results showed that the sensitivity and specificity of contrast-enhanced CT in the diagnosis of pelvic lymph node metastasis in ovarian cancer were 45.00%and 73.08%,respectively;Pelvic MRI plain scan has a sensitivity of 60.00%and a specificity of 80.77%in the diagnosis of pelvic lymph node metastasis in ovarian cancer;The combination of abdominal and pelvic enhanced CT and pelvic MRI plain scan has a sensitivity of 85.00%and a specificity of 92.31%in the diagnosis of pelvic lymph node metastasis in ovarian cancer.Conclusions In the diagnosis of lymph node metastasis in ovarian cancer,pelvic MRI has higher diagnostic sensitivity and specificity compared to abdominal and pelvic enhanced CT,but the combined use of the two achieves higher diagnostic efficacy.
