- 5-15 minutes: For a standard head or chest scan.
- 15-30 minutes: For more complex scans involving larger body areas or multiple scans.
Additional Factors Affecting Scanning Time
Keep in mind that certain factors can influence the scanning time, such as:
- Your health condition: If you have difficulty holding still or following instructions, the scan may take longer.
- Type of CT scanner: Different types of CT scanners vary in speed and efficiency.
- Radiologist’s interpretation: After the scan, the radiologist will need time to review the images and prepare a report, which may take 30 minutes or more.
