As a medical professional with expertise in diagnostic imaging, I can provide you with a detailed explanation of what a CAT scan of the chest can reveal.

A CAT (Computed Axial Tomography) scan is a non-invasive imaging technique that uses X-rays and computer technology to produce cross-sectional images of the body. When it comes to the chest, a CAT scan can show a variety of structures and potential issues:


1. Lung Tissue: It can detect lung conditions such as pneumonia, lung cancer, emphysema, and other lung diseases.

2. Heart and Great Vessels: The scan can reveal the size and shape of the heart and may show any enlargement, blockages, or abnormalities in the heart's chambers or valves.

3. Mediastinum: This is the area between the lungs that contains the heart, trachea, esophagus, and lymph nodes. A CAT scan can identify tumors, enlarged lymph nodes, or other abnormalities in this area.

4. Rib Bones and Sternum: It can show fractures, infections, or tumors in the rib bones and sternum.

5. Pleura: The scan can detect pleural effusions (fluid around the lungs) or pleural thickening.

6. Diaphragm: It can identify any paralysis or eventration (weakening) of the diaphragm.
7.
Blood Vessels: A CAT scan can be used to perform CT angiography, which is a detailed study of the blood vessels, looking for aneurysms, blockages, or other vascular issues.

A CAT scan is particularly useful because it provides detailed images that allow for the detection of small changes that might not be visible on a regular X-ray.

A chest CT scan is a more detailed type of chest x ray. ... Computers can combine these pictures to create three-dimensional (3D) models to help show the size, shape, and position of your lungs and structures in your chest. This imaging test is often done to follow up on abnormal findings from earlier chest x rays.read more >>
