概括
在治疗前的唾液腺扫描 (SGS) 可靠地预测了在分化甲状腺癌 (DTC) 患者接受放射性治疗后的唾液功能障碍和异构体. 这使得高风险个体的早期识别能够为定制的预防策略提供帮助.
科学领域:
- 核医学是一种核医学.
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
背景情况:
- 差异化甲状腺癌 (DTC) 患者经常接受放射性-131 (131I) 治疗.
- 唾液腺功能障碍和异口症是131I治疗的常见副作用.
- 预测这些不良反应的风险对于患者管理至关重要.
研究的目的:
- 评估预处理前唾液腺扫描 (SGS) 的预测能力,使用技术-99m基酸盐 (99mTcO4−).
- 评估DTC患者在131I治疗后出现中度至严重的唾液腺功能障碍和异口症的风险.
- 为了识别高风险的个人,为量身定制的预防策略.
主要方法:
- 149名DTC患者的回顾性招募,这些患者接受了全甲状腺切除术和131I治疗.
- 预处理SGS用于测量口腔腺和下下腺的吸收指数 (UI) 和分泌分数 (EF).
- 治疗后的SGS和异口腔评估使用异口腔库存 (XI) 评分.
主要成果:
- 131I治疗导致唾液腺体的UI和EF显著下降.
- 较高的131I剂量与中度至重度异口症的发生率增加相关.
- 治疗前的UI可靠地预测了所有腺体中适度至严重的功能衰退 (ΔUI%>20%) 与高AUC值.
- 下腺ΔUI%在异口症严重程度组之间有显著差异.
结论:
- 治疗前99mTcO4− SGS吸收指数是DTC患者在131I治疗后唾液腺功能障碍和异构的可靠预测指标.
- 早期识别高风险个体是可能的.
- 这使得能够实施量身定制的预防策略,以减轻不利影响.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
169
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...

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
