呼吸运动对手术前CT导向肺结节局部化的影响
1Department of Radiology, Peking University People's Hospital, No.11 Xizhimen South Street, Xicheng District, Beijing, PR China.
在CT导向定位期间,肺结节的运动幅度在下叶更大,增加扫描时间和程序持续时间. 然而,它不会影响技术成功率或并发症率.
科学领域:
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 计算机断层扫描 (CT) 引导的皮肤穿刺肺部穿刺对于诊断和治疗肺结节至关重要.
- 了解呼吸运动对结节局部的影响对于优化程序效率和安全至关重要.
研究的目的:
- 在手术前CT导向定位期间,评估不同位置的肺结节运动幅度.
- 评估呼吸运动对CT指导皮肤穿刺肺部穿刺结果的影响.
主要方法:
- 对398名接受了手术前CT指导肺结节局部化的患者进行了回顾性分析.
- 统计分析与呼吸运动相关的结节幅度,患者/损伤/手术特征.
- 单变量和多变量逻辑回归以确定影响因素.
主要成果:
- 节点运动幅度与上/中和下叶有显著的相关性.
- 运动幅度独立增加了CT扫描时间和手术持续时间.
- 穿孔深度是扫描时间,手术持续时间,技术故障和并发症的独立风险因素.
- 患者的位置影响了并发症的发生率 (肺胸部,脑膜出血).
结论:
- 在下叶节点的较大节点运动导致CT扫描时间和辐射剂量增加,局部化持续时间更长.
- 结节运动幅度没有显著影响技术成功率或并发症发生率.
- 优化患者的位置是最大限度地减少肺胸部和出血等并发症的关键.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...
Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
