CT Scan Explained: Uses, Procedure, and Factors Affecting CT Scan Price

A CT (Computed Tomography) is an extremely common imaging modality that provides detailed, cross-sectional views of all types of tissues in the body. It is used to take images of internal organs, bones, soft tissues and blood vessels. Unlike the regular X-ray scans, a CT scan doesn’t use any ionising radiation. This imaging modality aids healthcare providers to evaluate medical problems such as cardiovascular disease, infectious disease, cancers, trauma and musculoskeletal disorders. It can be used to evaluate the spine, chest, heart, shoulders, abdomen, head and knees. 

The scan helps in identifying internal injuries and bleeding, detecting tumours, infections and blood clots. It is also a useful tool in guiding surgeries and biopsies as surgeons rely mainly on CT images to guide needle biopsies. CT scans are used by clinicians to determine how well a treatment is working. Since the scan gives a much clearer picture of bones and joints, it can help evaluate complex fractures and degenerative conditions.

When compared to an X-ray, a CT scan provides much more detailed images which makes it a good option in distinguishing between different types of soft tissues. When put together in a 3D model, much broader level of information could be obtained about the condition. 

A CT scanner looks like a cylindrical machine that has a large hole in the middle and is open at both ends. The gantry houses the X-ray tubes and detectors which rotate around a person to capture images from all angles. For the procedure, the patient needs to lie on a flat, motorised table that gently slides. However, unlike MRI machines, CT scanners don’t feel fully enclosed. 

CT Scan price will depend on the body parts which you want to scan.
