概括
添加2-deoxy-2-18F-fluoro-D-glucose-positron发射断层扫描 (18F-FDG-PET) /CT扫描显著提高了骨活检的准确性. 这种分子成像指导减少了骨损伤患者的不确定的结果和错误诊断.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 核医学就是核医学.
背景情况:
- 计算机断层扫描 (CT) 引导的皮肤穿透核心活检是诊断骨损伤的标准.
- 对于小,异质或放射性微妙的骨病变,CT导向活检存在挑战,可能导致误诊或重复手术.
研究的目的:
- 评估2-deoxy-2-18F-fluoro-D-glucose-positron发射断层扫描 (18F-FDG-PET) /CT成像是否可以增强常规的CT引导骨活检.
- 确定分子图像指导是否通过改善异质性或放射性不明确病变的检测来优化活检策略.
主要方法:
- 一项前性研究包括了106名接受CT指导骨活检 (脊椎或外围) 的患者.
- 患者被分为两个组:36人接受了活检前的18F-FDG-PET/CT (PET组),70人只接受了标准CT扫描 (CT组).
- 活检结果根据他的病理学分类.
主要成果:
- 与CT组相比,PET组的结论性活检率 (92%) 显著高于CT组 (76%;p < 0.05).
- 在PET组 (1.9) 和CT组 (2.54;p = 0.051) 中,第一次试验活检的平均数量较低.
结论:
- 18F-FDG-PET/CT成像显著增加了首次试验CT引导骨活检的诊断成功率.
- 添加18F-FDG-PET/CT减少了不确的活检和误诊,优化了骨损伤的诊断途径.

4.1K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

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...
