The exam takes between thirty minutes to an hour. You will receive an injection of contrast dye beforehand, which allows for a clearer picture to be taken.
The procedure is painless, although it can be uncomfortable to remain still for the imaging. In some cases, the enclosed nature of the scanner can cause anxiety, in which case mild sedation can be arranged.
