概括
在18F-FDG PET/CT扫描过程中,预水和强制性尿液治疗方案显著改善了尿液膀放射标志物冲洗. 这提高了瘤与膀的比率,改善了初级盆腔瘤检测.
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:
- 18F-FDG PET/CT越来越多地用于初级盆腔瘤 (PT) 评估.
- 标准化水化方案对于最佳的利尿剂效果和一致的18F-FDG PET/CT结果至关重要.
- 膀活动可能会干扰PT可视化和评估.
研究的目的:
- 为了比较四种不同的水化方案在尿膀和原发性骨盆瘤中对18F-FDG吸收的有效性.
- 确定最佳的水合策略,以改善18F-FDG PET/CT.中的瘤-膀SUVmax比率.
主要方法:
- 对109名接受18F-FDG PET/CT.的PTs患者进行了回顾性审查.
- 评估了四种水化方案:没有水化,扫描后口服水化,扫描后口服水化和furosemide的IV水化,以及扫描后IV水化和furosemide的注射前口服水化.
- 量化尿膀和PTs的最大标准化吸收量 (SUVmax),并计算PT/UB SUVmax比率.
主要成果:
- 与其他组相比,涉及先水化,其次是静脉水化,口服水化和furosemide (组4) 的协议显著降低了UB SUVmax.
- 第4组在早期扫描中显示出明显更高的PT/UB SUVmax比率.
- 在4组中观察到PT的52.5%阳性率.
结论:
- 预水加强制性尿液的协议是最优的,以实现有效的尿液膀辐射标志物冲洗.
- 该协议显著提高了PT/UBSUVmax比率,提高了18F-FDG PET/CT对原发性盆腔瘤的诊断准确度.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
86
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...
