目的探讨宫颈癌磁共振成像(MRI)分期与病理分期的相关性。方法 80例经手术或活检病理证实的宫颈癌患者行盆腔MRI检查,MRI的成像序列包括T1加权像、T2加权像、脂肪抑制T2加权像、弥散加权成像,以及钆喷酸葡胺增强T1加权像。观察肿瘤的位置、信号特征及侵犯范围。将MRI所见与病理结果相对比。结果 MRI对宫颈癌分期总的准确率为88.73%。对宫旁侵犯判断的准确率为92.50%,特异度为91.18%,敏感度为100%。MRI与病理诊断的差异主要与宫旁浸润的评价差异有关。结论 MRI在宫颈癌临床分期中具有很高的准确性,是宫颈癌诊断中重要的影像学手段。
Objective To investigate the correlation between magnetic resonance imaging (MRI) staging and pathological staging of cervical cancer. Methods 80 cases of cervical cancer confirmed by surgery or biopsy were examined by pelvic MRI. The imaging sequences of MRI included T1 weighted image, T2 weighted image, fat suppression T2 weighted image, diffusion weighted imaging, and gadopentetate mepivudine enhanced T1 weighted Like Observe the location of the tumor, signal characteristics and extent of violations. Compare MRI findings to pathologic findings. Results The total accuracy rate of MRI in cervical cancer staging was 88.73%. The accuracy rate of judging uterine invasion was 92.50%, the specificity was 91.18% and the sensitivity was 100%. The difference between MRI and pathological diagnosis is mainly related to the evaluation of parametrial invasion. Conclusion MRI has a high accuracy in the clinical staging of cervical cancer and is an important imaging method in the diagnosis of cervical cancer.
