Which specialist performs CT scan?

The radiographer checks your identity and instructions, positions you on the scanning table, and operates the CT equipment from a nearby control room. A radiologist selects or approves the imaging protocol and interprets the resulting pictures. Contrast material may be used to make certain organs or blood vessels easier to see; the team checks relevant allergies and kidney concerns before giving it.

Follow instructions about fasting or drinking if contrast is planned. Tell the imaging service about pregnancy, previous contrast reactions, kidney disease, diabetes medicines, or difficulty lying flat. Wear comfortable clothing and remove metal objects when asked. You may need to remain still and briefly hold your breath during image capture.

Tell the team immediately if you feel unwell during the scan or after contrast. Seek urgent help for breathing difficulty, facial swelling, widespread rash, faintness, or severe weakness. For an outpatient scan, report persistent vomiting or other new symptoms to the service that arranged the examination.

Ask what body area will be scanned, whether contrast is needed, how the images will be reviewed, and when the referring clinician expects to discuss the report.
