MRI or Magnetic Resonance Imaging abdomen is a procedure used to make detailed images of the organs in the abdomen. MR urography evaluates the problems in the urinary tract using Magnetic Resonance.
What is MR Urography2?
MR urography is used to examine the urinary tract for abnormalities. MR urography is of two types, static-fluid MR urography, and excretory MR urography. Static fluid MR urography treats the urinary tract as a static column of fluid. Excretory MR urography uses a contrast agent, after which the collecting systems are imaged during the excretory phase. The MR urography is a non-invasive technique that provides comprehensive imaging of the urinary tract without using radiation.
How is MR Urography performed?
The conduct of both types of MR urography differs slightly1.
- The technician will ask you to lay on the MRI table, and during the course of the test, you may be asked to change positions.
- Devices that send and receive radio waves may be placed around your abdomen.
- If a contrast material is used an intravenous line will be inserted in your arm or hand.
- You will be moved through the MRI machine.
- You may be asked to wait after the first round of imaging in case additional images are needed. After this, your IV line will be removed (if there was any).
MR Urography might include multiple runs of several minutes.
Side effects of MR Urography
MR Urography is a fairly safe procedure due to the lack of use of radiation, except for the following risks1:
- There is a chance of allergic reaction to the contrast material if it is used.
- Complications can arise if the patient has a weak kidney.
Preparation before performing MR Urography
The patient should keep these things in mind before performing MR Urography
- Talk to your doctor or technician and tell them about any health complications or allergies to contrast materials, especially gadolinium medications.
- You might be asked to not eat or drink for a certain amount of time before the MR Urography.
- Prior to MR urography, any metal accessories or piercings should be removed from the body.
Post-care after MR Urography
One may experience headache, nausea, and pain at the site of the injection of the contrast after the MR urography. Contact your doctor in case of any allergic symptoms.
