目的 探讨各种不同序列在显示转移性肿瘤病灶中的作用。材料与方法 收集15例脊柱转移性肿瘤,其中乳腺癌骨转移4例,前列腺癌骨转移5例,肺癌骨转移6例,全部病例均有明确的原发病灶,均经临床病史及追踪随访6月以上确诊。行颈椎、胸椎、腰椎SE序列+增强、反相GE、同相GE、STIR序列检查。结果 反相GE序列(47/49)与SE+增强(44/49)显示病灶能力相当,同相GE序列显示的病杜(34/49)低于反相GE序列(47/49)及SE+增强(44/49),反相GE序列(47/49)及SE+增强序列(44/49)检出的病变数目相近,接近STIR序列。结论 脊柱转移瘤的检测中可以将SE序列与反相GE序列结合起来,既可高敏感性地检测出转移病灶,也可减少检查时间。
Objective To explore the role of various sequences in the display of metastatic tumor lesions. Materials and Methods Fifteen cases of metastatic spine tumors were collected, including 4 cases of bone metastasis of breast cancer, 5 cases of bone metastasis of prostate cancer and 6 cases of bone metastasis of lung cancer. All the cases had definite primary lesions, all of which were confirmed by clinical history and follow- Month or more confirmed. Cervical spine, thoracic spine, lumbar SE sequence + enhancement, reverse GE, in-phase GE, STIR sequence check. Results Inverted GE (47/49) was comparable to SE + enhancement (44/49), and lesions in phase GE were lower (34/49) than in reverse GE (47/49) and SE + 44/49), reverse GE (47/49) and SE + enhancement (44/49) were similar to the number of lesions, close to the STIR sequence. Conclusion The detection of spinal metastases can combine SE sequence with reverse GE sequence, which can not only detect the metastatic lesions with high sensitivity but also reduce the examination time.
