概括
较大的穿孔活检针 (17/18G) 在CT指导肺活检期间,与较小的针 (19/20G) 相比,不会增加肺胸风险. 然而,18G系统为病理结果提供了更高的敏感性,并且通道长度是并发症的关键预测因素.
科学领域:
- 肺部医学 肺部医学
- 干预性放射学 干预性放射学
- 在瘤学瘤学.
背景情况:
- 较大的穿孔活检针可以提高分子测试样本的质量.
- 人们担心,使用较大的针头增加了肺胸病风险.
- 这项研究调查了与不同样本检查针尺寸相关的并发症率.
研究的目的:
- 在CT导向肺活检中比较17/18-gauge (18G) 和19/20-gauge (20G) 活检系统之间的并发症率.
- 为了确定肺胸部和胸腔管插入的风险因素.
- 为了评估不同尺度活检系统的诊断灵敏度.
主要方法:
- 193个CT指导肺活检 (2013-2021) 的回顾性分析.
- 患者被分为18G和20G活检系统组.
- 收集的数据包括针标尺,结节特征,通道长度和结果 (肺胸,胸管插入).
主要成果:
- 整体肺胸病率为35.2%,其中10.9%需要插入胸管.
- 在18G和20G系统之间,肺胸或胸管率没有显著差异.
- 18G系统表现出比20G系统 (79.5%) 更高的病理敏感性 (93%).
- 增长的内肠道长度 (>2厘米) 和较小的结节与更高的肺胸病风险有关.
结论:
- 19/20G与17/18G活检系统的肺胸腔和胸管插入率相似.
- 18G系统为病理诊断提供了更高的灵敏度.
- 内膜体内针管的长度是肺胸部的关键预测因素;目标为<2厘米可能会降低风险.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
89
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...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
