MRI与CT检查对卵巢癌病理分期及复发转移的诊断价值对比研究

摘要 目的：对比磁共振成像（MRI）与计算机断层扫描（CT）检查对卵巢癌病理分期及复发转移的诊断价值。方法：纳入2017年1月～2019年1月于我院接受诊治的卵巢癌患者100例进行研究。所有患者术前均进行MRI与CT检查，并以术后病理组织活检结果为金标准，对比MRI与CT诊断卵巢癌与卵巢癌病理分期的准确率。所有患者均于首次检查6个月后进行复诊，对比MRI与CT诊断卵巢癌复发转移的准确率。结果：MRI诊断卵巢癌的确诊率为94.00%（94/100），高于CT诊断的81.00%（81/100）；漏诊率为2.00%（2/100），低于CT诊断的10.00%（10/100）（均P＜0.05）。MRI诊断卵巢癌Ⅰ期、Ⅱ期、Ⅲ期的准确率分别为93.33%（14/15）、95.00%（19/20）、93.33%（28/30），高于CT诊断的60.00%（9/15）、65.00%（13/20）、73.33%（22/30）（均P＜0.05）。MRI诊断肠管及周围、盆腔淋巴结、腹膜后淋巴结、肝脏等远处侵袭和转移中的准确率分别为100.00%（26/26）、88.89%（24/27）、75.00%（18/24）、95.00%（19/20），高于CT诊断的76.92%（20/26）、48.15%（13/27）、41.67%（10/24）、45.00%（9/20）（均P＜0.05）。结论：相较于CT检查，MRI检查诊断卵巢癌的准确率更高，漏诊率更低，且在卵巢癌病理分期以及复发转移的诊断准确率更高，具有较好的临床应用价值。

Comparative Study of the Diagnostic Value of MRI and CT in the Pathological Stage, Recurrence and Metastasis of Ovarian Cancer

ABSTRACT Objective: To compare the diagnostic value of magnetic resonance imaging (MRI) and computed tomography (CT) in the pathological stage, recurrence and metastasis of ovarian cancer. Methods: 100 patients from January 2017 to January 2019 with ovarian cancer were included in the study. All patients were examined by MRI and CT before operation, the gold standard was the result of pathological biopsy, the accuracy of MRI and CT in the diagnosis of ovarian cancer and pathological staging of ovarian cancer was compared. All patients were reexamined 6 months after the first examination, and the accuracy of MRI and CT in the diagnosis of recurrence and metastasis of ovarian cancer was compared. Results: The correct diagnostic rate of MRI in diagnosing ovarian cancer was 94.00% (94/100), which was higher than 81.00% (81/100) of CT diagnosis, the missed diagnosis rate was 2.00% (2/100), which was lower than 10.00% (10/100) of CT diagnosis (all P<0.05). The accuracy of MRI in the diagnosis of phase I, II and III of ovarian cancer was 93.33% (14/15), 95.00% (19/20), 93.33% (28/30), which were higher than 60.00% (9/15), 65.00% (13/20), 73.33% (22/30) of CT diagnosis (P<0.05). The accuracy of MRI in the diagnosis of distant invasion and metastasis at intestine and surrounding, pelvic lymph nodes, retroperitoneal lymph nodes, liver and beyond were 100.00% (26/26), 88.89% (24/27), 75.00% (18/24), 95.00% (19/20) respectively, which were higher than 76.92% (20/26), 48.15% (13/27), 41.67% (10/24), 45.00% (9/20) of CT diagnosis(P<0.05). Conclusion: Compared with CT, MRI have higher correct diagnostic rate and lower missed diagnosis rate in the diagnosis of ovarian cancer, which has a better clinical application value.
