- 肺部病理学 肺部病理学
- 传染性疾病 传染性疾病
背景情况:
- 在CT扫描上区分COVID-19感染后的残留肺异常与先前存在的间歇性肺异常 (ILA) 是一个诊断挑战,特别是在有限的临床数据的情况下.
- 准确的区分对于适当的患者管理和预后至关重要.
研究的目的:
- 评估放射科医生在区分COVID-19后的残留肺异常与ILA的诊断性能,使用胸部CT扫描.
- 评估不同经验水平的放射科医生之间的协议.
主要方法:
- 一个多读者,多病例研究,涉及60名参与者 (20名COVID-19后,20名纤维化ILA,20名非纤维化ILA) 胸部CT扫描.
- 15名放射科医生独立评估了怀疑得分,以区分COVID-19后异常与纤维化和非纤维化ILA.
- 用接收器操作特征 (ROC) 曲线分析评估诊断性能,用加权卡帕 (κ) 值评估观察者之间的一致性.
主要成果:
- 放射科医生在区分COVID-19后残留异常与ILA方面表现出良好的诊断性能,ROC曲线下的中位面积 (AUC) 为0.85和中度一致 (κ = 0.56).
- 与非纤维性ILA (AUC = 0.80) 相比,当与纤维性ILA (中位数AUC = 0.89) 区分时,诊断性能更高.
结论:
- 放射科医生表现出良好的诊断能力和在区分COVID-19后的残留肺异常与ILA方面中等的协议.

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...

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...

01:20Imaging Studies for Cardiovascular System III: X-Ray
150
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...
