We report a case in which malignant melanoma of the vagina showed some MR signal changes after radiotherapy. Before radiotherapy, the tumour had slightly high signal intensity on T(1) weighted images and was enhanced after gadolinium-DTPA administration. After radiotherapy, the signal intensity of the tumour increased conspicuously on both T(1) weighted images and fat suppression T(1) weighted images.
我们报告了一例阴道恶性黑色素瘤在放疗后出现一些磁共振信号变化的病例。放疗前，肿瘤在T1加权图像上呈略高信号强度，注射钆喷酸葡胺后强化。放疗后，肿瘤在T1加权图像和脂肪抑制T1加权图像上的信号强度均显著增加。
