A CT scan (Computed Tomography) is an advanced diagnostic imaging test that uses X-rays and computer processing to create detailed cross-sectional images of the body. It helps doctors examine bones, organs, blood vessels, soft tissues and internal structures with greater detail than a conventional X-ray. CT scans are commonly used to evaluate injuries, infections, abdominal conditions, chest problems, neurological concerns and other medical conditions.
What Does a CT Scan Detect?
Depending on the area being examined, a CT scan may help doctors identify internal bleeding, fractures, tumors, infections, inflammation and other abnormalities. Specialized examinations include CT brain scan, chest CT, abdominal CT, pelvic CT, CT angiography and spine CT.
CT Scan Preparation
Preparation depends on the type of examination and whether contrast material is required. Patients may be advised to avoid food or drinks for a few hours before certain scans. Inform your doctor about allergies, medications, kidney disease, thyroid problems, or possible pregnancy before the examination.
Benefits of CT Scan
A CT scan is generally fast, painless and non-invasive and can provide detailed images that support diagnosis and treatment planning. Contrast-enhanced CT may improve visibility of selected organs, tissues and blood vessels.
