Summary
Systemic lupus erythematosus (SLE) commonly affects the chest, with infections and pulmonary hypertension being frequent findings on CT scans. This study highlights the diverse thoracic manifestations of SLE and their diagnostic importance.
Area of Science:
- Radiology
- Immunology
- Pulmonology
Background:
- Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease.
- Thoracic involvement in SLE significantly contributes to patient morbidity and mortality.
- Computed tomography (CT) is essential for diagnosing thoracic manifestations in SLE patients.
Purpose of the Study:
- To evaluate the spectrum and frequency of thoracic manifestations of SLE using CT imaging.
- To identify common and less frequent CT findings in SLE patients.
- To correlate thoracic findings with extra-thoracic manifestations.
Main Methods:
- Prospective, cross-sectional observational study over 18 months.
- Included 60 adult SLE patients referred for chest CT.
- Utilized high-resolution CT, contrast-enhanced CT, or CT pulmonary angiography based on clinical need.
Main Results:
- Infection was the most common thoracic diagnosis (53.3%), primarily bacterial.
- Pulmonary arterial hypertension (50%) and pulmonary edema (18.3%) were frequent vascular findings.
- Interstitial lung disease (10%), serositis (10%), and splenomegaly (51.7%) were also observed.
Conclusions:
- Thoracic involvement in SLE is diverse, with infections and vascular issues being most prevalent.
- CT imaging is crucial for diagnosing overlapping thoracic patterns in SLE.
- Accurate CT diagnosis aids in guiding appropriate clinical management for SLE patients.

01:20Imaging Studies for Cardiovascular System III: X-Ray
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...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
