概括
通过计数扩大的外侧阴淋巴结和通过骨光学评估血液流动来改善诊断周围假肢关节感染 (PJI). 这种综合方法比PJI检测的传统标记器提供了更高的准确性.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 传染性疾病 传染性疾病
背景情况:
- 下肢感染通常会导致外阴淋巴结的反应性扩大和血液流量增加.
- 从临床上来说,区分无菌松动与关节周围假肢感染 (PJI) 的关节置换后是重要的.
研究的目的:
- 评估量化扩大的外侧阴淋巴结的诊断价值,并通过骨光学评估血液流动,以区分无菌松与PJI.
- 将这些成像技术的诊断准确性与已确定的炎症标志物进行比较.
主要方法:
- 包括124名接受过无菌松或PJI修复手术的患者.
- 进行了手术前的双能计算断层扫描 (DECT) 进行淋巴结评估和骨扫描进行血液流动评估.
- 使用接收器操作特征 (ROC) 曲线分析来确定诊断值.
主要成果:
- 与无菌性失败组相比,PJI组显示出显著增加的外侧阴道淋巴结 (4.0对1.0,p < 0.001) 和更高的血液池相比率在骨头扫描 (1.49对1.04,p < 0.001).
- 诊断PJI的曲线下的面积 (AUC) 为淋巴结数量为0.91,骨光学血池阶段为0.89.
- 结合这两个指标,AUC为0.95,超过ESR (0.83),CRP (0.76) 和突液PMN% (0.62).
结论:
- 淋巴结数量的扩大与骨光学血池阶段相结合,是诊断PJI的高效方法.
- 与传统的炎症标志物相比,这种综合成像方法显示出更高的诊断性能.
- 这种方法为准确的PJI诊断提供了一个有希望的,非侵入性的策略.

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...
