Question: I was wondering what the difference between a mra and a mra with contrast is. I had a regular mra of my neck and arteries to check for a torn carotid artery, but was concerned if something like that would show without contrast.

Brief Answer:
Contrast is not obligatory in every MRI scan

Detailed Answer:
Dear Ms,

MRI with contrast injection used to make more visible some structures. There is no need for contrast MRI in every examination.
There are examinations e.g. heart scan which usually done with contrast, and there are some examinations that can be done both with contrast or without it.
If during the scan the physician notices that there is not enough visibility, then they continue with contrast.
If they performed the scan without contrast, it means they could obtain all the information they needed without it.
So, don't worry.

Take care
