概括
水凝肺道密封剂 (h-LTS) 在CT导向肺活检后会产生蛇形性痕. 这种痕可能表现出轻度的FDG吸收,并持续长达五年,最初怀疑患有低至中度恶性瘤.
科学领域:
- 放射学 放射学是一门学科.
- 肺部病理学 肺部病理学
- 在瘤学瘤学.
背景情况:
- CT导向肺活检 (CTLB) 是一种常见的诊断程序.
- 水凝肺道密封剂 (h-LTS) 用于潜在地减少并发症.
- 剖析后h-LTS的成像特征需要详细的评估.
研究的目的:
- 评估CTLB后与h-LTS相关的成像发现.
- 为了评估这些发现的恶性瘤怀疑随着时间的推移.
- 为了比较患有h-LTS和没有h-LTS的患者的成像.
主要方法:
- 对接受CTLB治疗的h-LTS或没有h-LTS的患者的回顾性图表审查.
- 在多次间隔下对剖析后CT和FDG-PET/CT成像进行分析.
- 对活检通道异常和恶性瘤的怀疑进行读者间协议评估 (类别1-5).
主要成果:
- 在60%使用h-LTS的患者中观察到一种形痕,持续平均23.3个月.
- 对于痕异常的适度互读者协议被注意到.
- 轻度FDG吸收在46%的h-LTS痕中被观察到长达5年的时间,最初的恶性瘤怀疑被评为3类或更高的17%.
结论:
- 在成像上,h-LTS与特征性的蛇形性痕有关.
- 这些痕可以在FDG-PET/CT上表现出轻微的超能代谢,并持续数年.
- 与h-LTS痕相关的恶性瘤的怀疑通常会随着时间的推移而减少或保持稳定.

82
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
