A CT (Computed Tomography) scan uses computer-processed combinations of many low dose X-ray measurements taken from different angles to produce cross-sectional images of specific areas.
CT examinations can image every type of body structure including bone, blood vessels and soft tissue. For the patient, a CT scan is a non-invasive, painless and relatively safe procedure that doesn’t require any recovery time.
There are a number of reasons for the doctor to ask for a CT scan, in particular the diagnosis of disease or injury, an aid to planning surgery or radiotherapy and as an alternative to some types of exploratory or diagnostic surgery.
CT Scans can also be used to guide the Radiologist when performing biopsies or pain management injections.
