概括
在治疗前的放射性成像诊断 (dx WBI) 是有争议的,并且经常被放弃. 然而,治疗后的成像对于分化甲状腺癌 (DTC) 的分期和识别放射性的瘤至关重要.
科学领域:
- 核医学就是核医学.
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
背景情况:
- 放射性成像在完全甲状腺切除术后的外科设置中使用.
- 治疗后全身成像 (PT-WBI) 的好处已经确立,但治疗前诊断成像 (dx WBI) 仍在争论中.
- Dx WBI对检测小转移性病变的敏感性较低,可能导致甲状腺残留物被误解为结节疾病.
研究的目的:
- 评估诊断全身成像 (dx WBI) 在差异化甲状腺癌 (DTC) 初始外科设置中的作用和局限性.
- 突出治疗后放射性成像和SPECT/CT对DTC患者准确分期和风险分层的重要性.
主要方法:
- 关于DTC中治疗前后放射性成像的现行实践和文献的审查.
- 平面低剂量dxWBI与现代集成SPECT/CT成像技术的比较.
- 分析不同成像方式的诊断准确度和超神学功率.
主要成果:
- Dx WBI具有有限的价值,无法检测隐藏的转移,并且可能导致由于误解甲状腺残留物的错误解释而导致虚假的N升级.
- 综合SPECT/CT提供了更好的解剖学和代谢数据,但与平面成像相比,不一定具有更高的灵敏度.
- 切除后的I-131成像对于分期放射性激活的DTC和识别非激活瘤至关重要.
结论:
- 预处理dx WBI是有争议的,并且由于敏感性低和误解的可能性,经常被放弃.
- 治疗后I-131成像是所有接受放射性治疗的DTC患者的义务.
- 在治疗后设置中的SPECT/CT增强了DTC患者的TNM初始分期和风险分层.

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...
