概括
附带循环可以在PET/CT扫描上引起假阳性骨病变,模仿转移. 即使没有明显的血栓形成,这种情况也会发生,这凸显了核医学医生的关键诊断陷.
科学领域:
- 核医学是一种核医学.
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 附带循环,通常是由于血栓形成引起的,可能导致对成像检测结果的误解.
- 在正子发射断层扫描/计算机断层扫描 (PET/CT) 扫描上出现错误阳性的骨损伤是已知的诊断挑战.
- 附带循环在模仿转移性疾病中的作用需要进一步阐明.
研究的目的:
- 介绍一下在PET/CT上附带循环模仿骨转移的情况.
- 要突出在没有明显的血栓形成的情况下,附带循环的诊断影响.
- 强调临床相关性在解释模两可的骨吸收中的重要性.
主要方法:
- 使用18F-FDG和18F-胆进行PET/CT成像的两个病例的审查.
- 与临床随访相关的成像发现的分析.
- 放射性追踪剂吸收与血栓形成过程的存在或不存在的相关性.
主要成果:
- 这两种病例在PET/CT扫描上都显示出异常的骨吸收.
- 吸收模仿骨转移,特别是与18F-FDG和18F-胆.
- 临床随访证实没有转移,并将发现归因于附带循环.
结论:
- 附带循环可以在PET/CT上呈现为假阳性骨病变,模仿转移.
- 这种现象即使没有可检测的急性或慢性血栓形成,也可能发生.
- 仔细解释和临床相关性至关重要,以避免错误诊断骨转移.

4.2K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
