摘　　要：我们对20例恶性淋巴瘤患者治疗前后进行了检查,并分别测量了肿瘤、皮下脂肪及肌肉的信号强度,对所得数据进行了标准化处理.结果表明,治疗后所有病人的信号强度标准化值均明显减小,减小的程度标定着肿瘤纤维化的程度;MRI的T_2WI图像可对复发或残留瘤灶与纤维肿块间作出鉴别,因此,恶性淋巴瘤治疗前后MRI检查有着重要的临床指导意义.Twenty patients with mediastinal involvements of lymphadenoma were examined with magnetic resonance imaging before and after treatment, and the signal intensities of tumor,subcutaneous fat or muscle were measured. After treatment,a significant decrease in signal intensity ratios of tumor to fat and tumor to muscle was found in all patients. MRI, particularly T2-weighted images were most helpful to distinguishing recurrent tumor from fibrotic tissue. Since the degree of low signal intensity in the tumor before treatment probably reflects the amount of fibrotic tissue, these results support the hypothesis that residual masses after treatment are remnants of the fibrotic stroma of the original tumor.
