摘要
目的:探讨MRI在评估诊断宫颈癌复发中的价值。方法:36例经病理证实宫颈癌复发患者,均行盆腔的MRI轴位T1WI、T2WI、SPIR以及GD-DTPA增强扫描后T1WI轴位、矢状位扫描。在不同序列MRI图像上观察复发肿瘤的形态、大小及信号改变。结果:326例病人中出现复发36例,发生率为11%。25例宫颈癌手术后复发病例,MRI可见在阴道残端或盆腔内出现软组织信号肿块影,增强扫描可见肿块明显强化。其中5例可见肿块侵及一侧输尿管,其上方输尿管扩张积水。11例宫颈癌放化疗后复发病例,MRI可见宫颈较前明显增厚,肿块T1WI为略低信号,T2WI为略高信号,增强扫描可见肿块呈不均匀强化。其中2例可见肿块侵及膀胱壁。结论:由于MRI具有非常好的软组织分辨率,MRI成像已成为宫颈癌手术前后或放化疗前后检查和随访最重要的手段,它能够准确判断宫颈癌临床分期,并且可以早期、及时发现肿瘤复发;在评估宫颈癌复发诊断中有重要价值。
Objective： To explore value of MRI in the diagnosis of cervical cancer recurrence.Methods： All 36 patients with pathologically confirmed recurrent cervical cancer patients underwent pelvic MRI axial T 1 WI,T 2 WI,SPIR,and GD-DTPA enhanced T 1 WI axial scan,sagittal scan.MRI images in different sequences observed recurrence of the tumor shape,size and signal change.Results： Among 326 cases,36 patients were found to be recurrent,the rate was 11%.25 cases of cervical cancer recurrence after surgery,MRI can be seen in the vaginal stump or pelvic mass in the presence of soft tissue signal,enhanced scan showed mass significantly enhanced,5 cases showed mass violations to the side of the ureter,ureter expansion of water above it,11 cases of cervical cancer recurrence after radiotherapy and chemotherapy,MRI images was significantly thicker than before the cervix can be seen,the mass was slightly lower signal T 1 WI,T 2 WI was slightly higher signal,enhanced scan showed mass with heterogeneous enhancement,2 cases showed mass invading the bladder wall.Conclusion： Because MRI has a very good soft tissue resolution,MRI scans before and after surgery in cervical cancer or chemotherapy before and after the inspection and follow-up inspection is the most important tool;it can accurately determine the clinical stage of cervical cancer,and can be an early,timely detection of tumor recurrence,for diagnostic evaluation of recurrent cervical cancer has important value.
