Because of the differences in the signals from recurrent tumours and fibrosis during MRT, this method is highly suitable for differentiating between recurrent gynaecological tumours and scar formation. The value of MRT in investigating suspected recurrences was studied in 27 patients aged between 34 and 83 years. It was possible to distinguish between recurrent tumour with its high intensity signal from low signal fibrosis, using T2-weighted spin echo sequences in all cases. By means of multiplanar reconstruction and because of its high soft tissue contrast it was possible to determine the extent of tumour growth and differentiate it from surrounding tissues. With a sensitivity of 90%, specificity of 100% and accuracy of 92%, MRT is superior to all other imaging methods, including CT, in the diagnosis of tumour recurrence.
由于磁共振成像(MRT)过程中复发肿瘤和纤维化信号存在差异,该方法非常适合区分复发性妇科肿瘤和瘢痕形成。对27例年龄在34至83岁之间的患者进行了MRT在调查疑似复发情况中的价值研究。在所有病例中,使用T2加权自旋回波序列能够区分复发肿瘤的高信号与低信号纤维化。借助多平面重建且因其具有高软组织对比度,能够确定肿瘤生长范围并将其与周围组织区分开来。在肿瘤复发诊断方面,MRT的灵敏度为90%,特异性为100%,准确性为92%,优于包括CT在内的所有其他成像方法。
