| 目的 观察18F-FDG PET/CT显像对131I-治疗剂量全身显像（131I-RxWBS）阴性且甲状腺球蛋白（Tg）阳性分化型甲状腺癌（DTC）复发或转移的诊断价值及对治疗方案的影响。方法 对72例接受131I清除残留甲状腺并接受大剂量131I治疗后随访中发现Tg阳性而131I-RxWBS阴性DTC术后患者行18F-FDG PET/CT显像，将显像结果与手术病理或6~36个月临床随访结果进行对照，评价18F-FDG PET/CT显像对Tg升高而131I-RxWBS阴性DTC复发或转移的诊断效能。结果 18F-FDG PET/CT诊断Tg升高而131I-RxWBS阴性的DTC复发或转移的准确率、灵敏度、特异度、阳性预测值和阴性预测值分别为83.33%（60/72）、89.47%（34/38）、76.47%（26/34）、80.95%（34/42）和86.67%（26/30）。18F-FDG PET/CT显像改变了35例（35/72，48.61%）患者的治疗方案，其中23例（23/35，65.71%）接受手术者在临床随访中均未见甲状腺癌复发及转移，其余12例（12/35，34.29%）随访期内均显示病情进展。结论 对于131I-RxWBS阴性而Tg阳性的DTC患者，18F-FDG PET/CT有助于诊断和定位复发及转移病灶，指导后续治疗。 |

| Objective To observe the value of CE-MRA in differentiating secondary vascular tortuosity of the spinal cord caused by spinal vascular malformations (SCVM) or non-vascular malformations. Methods A retrospective analysis was performed on 30 patients suspected as SCVM. Based on the results of DSA or surgery, the patients were divided into SCVM group (n=16) or non-vascular malformation group (n=14). CE-MRA features were compared between the two groups, including the number, length, position, tortuosity degree of spinal cord tortuous vascular and whether the abnormal feeding artery existed surrounding tortuous vascular. Results Compared with non-vascular malformation group,SCVM group showed more average number of tortuous vascular, longer tortuous vascular lengthy and more easier to appear abnormal feeding artery surrounding tortuous vascular. Furthermore, only 2 cases (2/16, 12.50%) of tortuous vascular located in and limited to lower thoracic vertebra (T7-T12 vertebrae) in SCVM group, while 11 cases (11/14, 78.57%) in non-vascular malformation group (P=0.020). Conclusion Spinal cord secondary vascular tortuosity of SCVM can be well distinguished from that caused by non-vascular malformation with CE-MRA spinal angiography. |
