摘要
The purpose of this study was to assess the accuracy of MRI in the staging of intra-abdominal tumor seeding of ovarian carcinoma. Fifty-seven patients with suspected primary or recurrent ovarian carcinoma were included in this study. All patients received laparotomy within 8 weeks after MRI. The MRI protocol included fat-saturated T1-weighted spin-echo (SE) sequences pre- and post i.v. application of gadopentetate dimeglumine. The criteria for tumor manifestation was contrast enhancement of intra-abdominal soft tissue lesions or peritoneum. The image review was performed by a blinded radiologist, a specialist in gynecological and abdominal MR imaging. Results were compared with findings during laparotomy. Sensitivity, specificity, positive and negative predictive values, and corresponding 95% confidence intervals were calculated for single intra-abdominal locations and for groups of locations defined according to surgical strategies for intra-abdominal cytoreduction. Laparotomy and histopathology confirmed 251 abdominal tumor locations. Sensitivity was high in lower pelvis locations (73-83%) except for ureter or bladder infiltration (40%). Bowel or mesentery locations displayed sensitivity values from 73 to 77%. Sensitivity was very low for pelvic lymph nodes (28%), greater omentum (38%), and lesser sac (43%). Magnetic resonance imaging based on contrast-enhanced fat-saturated T1 SE sequences improves planning of cytoreduction preceding chemotherapy in advanced primary or relapsed ovarian carcinoma.
