A full CT scan typically takes about 30 minutes from start to finish, although the actual scanning time is much shorter.
Here's a breakdown:
- Preparation: A significant portion of the time involves preparation. This might include changing into a gown, discussing your medical history with the technician, and positioning you correctly on the CT scanner table.
- Scanning Time: The actual time spent in the CT scanner is usually less than 30 minutes. The precise duration depends on the area being scanned and the number of images required.
- Contrast Administration (If Applicable): If your CT scan requires contrast material (either oral or intravenous), it may take longer. Oral contrast requires time to be absorbed, potentially adding to the overall duration.
In summary, while the entire appointment can take up to a half-hour or slightly more, the CT scanning process itself is relatively quick.
