In the scanner
A knee, a brain or a lumbar spine study is often 15–40 minutes of scanning. You are in the department longer than that: changing, the safety form, and getting the images checked before you leave.
What makes it longer
- More than one body region.
- Contrast, which adds an injection and extra sequences.
- A repeated sequence if you moved.
- A whole-body protocol, which is often 45–90 minutes depending on the scanner.
The booking length the clinic gives you is the one to trust. A forum average is not your appointment.
