Abdomen MR Angiography- Benefits and Risks

Abdomen MRI angiography is a noninvasive imaging technique that does not involve exposure to ionizing radiation.
Detailed images of blood vessels and blood flow are obtained without having to insert a catheter into the blood vessels, so that there is no risk of damaging a major blood vessel.
The MRI angiography procedure itself may be shorter than a traditional catheter angiogram and requires no recovery period.
MR angiography is less costly than catheter angiography.
MR angiography can provide high-quality images of many blood vessels even without using contrast material, making it very useful for patients prone to allergic reactions or with reduced kidney function.
The contrast material used in MRI exams is less likely to produce an allergic reaction than the iodine-based contrast materials used for conventional x-rays and CT imaging.

The MRI examination poses almost no risk to the average patient.
Some patients experience greater claustrophobia with an MRI exam.
If sedation is used, there are risks of excessive sedation. The technologist or nurse monitors your vital signs to minimize this risk.
There is a very slight risk of an allergic reaction if contrast material is injected. If you experience allergic symptoms, a radiologist or other physician will be available for immediate assistance.
Nephrogenic systemic fibrosis is a serious, but rare complication believed to be caused by the injection of gadolinium contrast material in patients with very poor kidney function.
