概括

使用SPECT/CT的骨光学有效地将假肢关节感染与松动区分开来,比其他方法提供更高的准确性. 这种成像技术显示出改善关节置换手术后诊断的希望.

科学领域:

整形外科手术整形外科手术
核医学是一种核医学.
诊断成像诊断成像诊断成像

背景情况:

假肢松动和感染是关节置换手术后的常见并发症.
区分假肢松动和周围假肢感染仍然是一个临床挑战.
单光子发射计算机断层扫描-计算机断层扫描 (SPECT/CT) 提供了综合的解剖学和代谢信息,显示了改善诊断的潜力.

研究的目的:

评估骨光学与SPECT/CT结合的骨光学在区分假肢感染与关节置换后松动的有效性.
分析关节与膝盖假肢的差异诊断性能.
评估血液生物标志物在诊断周围假肢感染中的有用性.

主要方法:

在2015年至2021年期间,对74个假肢关节 (部和膝盖) 进行了回顾性分析,怀疑其松或感染.
评估包括核成像 (骨扫描,SPECT/CT),X射线和血清生物标志物.
通过电话跟踪和修复手术建立的黄金标准;使用奇平方测试和ROC曲线评估诊断准确性.

主要成果:

SPECT/CT结合骨光学显示出最高的灵敏度 (92.86%) 和准确度 (87.84%) 在区分感染和松方面.
这种混合成像方法的性能优于单个成像方法.
在关节置换术中,假肢松动更频繁,而膝关节假肢更容易感染 (P < 0.05). 对于ESR和CRP的敏感性分别为80%和84%.

结论:

使用混合SPECT/CT的骨光学是区分假肢感染与关节置换后松动的一个有价值的工具.
关节假肢的诊断效果优于膝关节假肢的诊断效果.
仅仅是血清生物标志物不足以区分假肢感染与松动.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...
