概括
定子发射断层扫描/计算机断层扫描 (PET/CT) 显示出高灵敏度的诊断巨细胞动脉炎 (GCA),优于动脉活检 (TAB) 和帮助诊断,特别是当进行早期后,葡萄糖皮质激素启动.
科学领域:
- 血管医学 血管医学
- 诊断成像 诊断成像 诊断成像
- 类风湿病学 类风湿病学
背景情况:
- 巨细胞动脉炎 (GCA) 的诊断依赖于临床怀疑和侵入性手术,如动脉活检 (TAB).
- 在GCA中PET/CT与TAB的诊断性能以及葡萄糖皮质体治疗的影响需要进一步评估.
研究的目的:
- 为了比较PET/CT与TAB在疑似GCA的患者的诊断效用.
- 评估葡萄糖皮质激素治疗对PET/CT和TAB诊断准确性的影响.
主要方法:
- 在5年内对157名接受TAB治疗的患者进行了回顾性队列研究.
- 患者被分为仅TAB和PET/CT+TAB组,以评估诊断性能.
- 在至少六个月的随访后,GCA的临床诊断得到了确认.
主要成果:
- 与临床诊断相比,PET/CT的灵敏度为76%,而TAB的灵敏度为63%.
- 当在葡萄糖皮质醇治疗的三天内进行时,PET/CT和TAB的灵敏度都增加了 (分别为85%和74%).
- 在15个案例中,PET/CT和TAB结果不匹配,负面同意率为19%.
结论:
- 传统的PET/CT是一种有价值的成像工具,用于诊断全谱GCA.
- PET/CT有助于评估受 GCA 影响的头骨和头骨外动脉.
- 在葡萄糖皮质激素启动后早期的PET/CT成像可能会改善诊断产量.

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
