You will be asked about the following:

You will be asked if you have something in your body that would interfere with the MRA, such as:

You may be:
- Given ear plugs or headphones to wear (The MRI machine makes a loud banging noise.)
- Given an injection of a contrast dye into your vein
- Allowed to have a family member or friend with you during the test
If contrast is used, a small IV needle will be inserted into your hand or arm before you are moved into the MRI machine. The contrast will be injected during one set of images. It helps to make some organs and vessels easier to see on the pictures. You might have an allergic reaction to the dye, but this is rare
You will lie on a special table. This table will be moved inside the opening of the MRI machine. Most MRIs will consist of 2-6 sets of images. Each one will take between 2-15 minutes. You will need to lie still while the images are being taken. You may need to hold your breath briefly. The technician will be in another room. You will be able to talk to her through an intercom.After Test
