概括
使用骨窗设置进行视觉评估,可以在肺RADS类别2非固体结节中区分侵袭性肺腺癌和非侵袭性病变. 这种简单的方法有助于区分这些疾病,提高诊断准确度.
科学领域:
- 肺部医学 肺部医学
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 侵入性腺癌 (IAD) 在肺成像报告和数据系统 (肺-RADS) 2类非固体结节 (NSN) 中被发现.
- 在此类别中,区分IAD与非侵入性病变 (NIL) 对于适当的患者管理至关重要.
研究的目的:
- 用骨窗 (BW) 设置评估视觉评估的有效性,以区分肺-RADS 2类NSN中的IAD和NIL.
- 确定NSN的BW可见性是否可以预测IAD的存在.
主要方法:
- 对222名患者的242个切除的NSN进行了回顾性分析.
- 使用肺和骨窗口设置对NSN进行视觉评估,将其分类为BW可见 (BWV) 或BW不可见 (BWI).
- 视觉分类和结节特征与使用后勤回归的组织病理学结果的相关性.
主要成果:
- 在242个NSN中,31%是IAD. 在BWI组中只发现了4个IAD (5.3%).
- 结节大小和视觉分类 (BWV vs. BWI) 是多变量分析中IAD的显著预测因素.
- 视觉分类显示IAD检测的高灵敏度 (94.7%) 和负预测值 (94.7%).
结论:
- 基于窗口的NSN视觉分类是一种简单而客观的方法来区分IAD和NIL.
- 将NSN分类为BW可见或BW不可见有助于区分侵袭性肺腺癌和非侵袭性肺腺癌.
- 肺-RADS类别2的NSN在骨窗口中没有可视化,不太可能是侵入性腺癌.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
97
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

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...
