概括
使用多平面重建 (MPR) 的简化手动路径规划方法与外围肺病变的虚拟支气管镜检查 (VB) 具有很高的一致性. 这种可访问的技术在VB系统失灵的情况下提供了优势,增强了诊断支气管镜检查.
科学领域:
- 肺部医学 肺部医学
- 医疗成像医学成像
- 干预性肺病学 干预性肺病学
背景情况:
- 通过支气管镜检查,准确地导航到外围肺病变,对于肺癌诊断至关重要.
- 使用CT扫描进行手动路径规划是有效但复杂的;简化可以提高可访问性.
- 虚拟支气管镜 (VB) 系统有局限性,需要使用替代的规划方法.
研究的目的:
- 评估使用多平面重建 (MPR) 的简化手动路径规划方法.
- 为了比较手动MPR规划与外围肺病变的VB系统的有效性.
主要方法:
- 对接受r-EBUS引导支气管镜检查的51名患者的CT扫描进行了回顾性分析.
- 路径规划使用VB系统 (阿基米德) 和简化的手动MPR方法由3名运营商执行.
- 两种方法之间的路径一致性和规划时间的比较.
主要成果:
- 手动MPR和VB之间的路径一致性为78.5% (40/51个案例).
- 手动方法确定了VB错过的7个额外的分叉,并在VB失败的3个情况下取得了成功.

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...

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...
