| 目的 探讨锁骨上区、肺门部位出现18F-FDG浓聚的确切组织。方法 回顾分析147例PET/CT全身检查结果及临床资料。结果 双侧颈部、锁骨上脂肪组织及胸肋椎关节显影8例,平均年龄44岁(26~74岁),阳性率为5.4%。 其中男2例,女6例, 阳性率分别为2.1%和11.3%。肺门血管显影5例 (年龄56~74岁),阳性率为3.4%。结论 双侧锁骨上区及肺门部位18F-FDG的摄取PET/CT证实并非都是骨骼肌和淋巴结组织,也可见于脂肪组织及肺门血管。双侧锁骨上脂肪组织显影多见于女性,与年龄无关;而肺门血管显影多见于老年患者,与性别无关。 |

| Objective To find out the exact tissues of the 18F-FDG uptake in the sites of the supraclavicular area and the lung hilus. Methods From September 2002 to March 2003, 147 consecutive clinical patients imaged by 18F-FDG PET/CT whole-body scan (GE Discovery LS, CT attenuation correction, OSEM reconstruction) were retrospectively reviewed. Results Of 147 patients, 8 cases (2 males, 6 females, mean age 44 years) were found with increased symmetrical 18F-FDG uptake in the fatty tissues of the lower neck and shoulder as well as costo-vertebral articulations, the positivity rates were 2.1% and 11.3% for men and women, respectively, and the average rate was 5.4%. Five patients (3 males, 2 females, age 56-74 years, 3.4%) were showed abnormal 18F-FDG uptake which definitely localized in the vascular structure of the lung hilus by CT. Conclusion Co-registered PET/CT imaging shows that the 18F-FDG uptake in the supraclavicular area and the lung hilus are not fully located in greater muscular structures and lymph nodes, but in the fatty tissue of the shoulders, costo-vertebral articulation complex of the thoracic spine as well as in the vascular structure of both lung hilus. The 18F-FDG uptake in the fatty tissue of the shoulder are mostly seen in women, while the uptake in vascular structure of the lung hilus are found in aged people. |
