Magnetic resonance imaging (MRI) of the rectum is a diagnostic imaging method that allows the morphology and structure of the rectal area to be studied. It is a non-invasive test that does not use X-rays or radioactive elements. Sometimes it may be necessary to administer a contrast material intravenously to obtain a clearer image of the area being examined. The most commonly used contrast medium is gadolinium.
CONTRAINDICATIONS
Absolute contraindications for magnetic resonance imaging include:
*Pacemakers and heart valves not specifically designed for use in magnetic resonance imaging.
* Cardioversion defibrillators.
* Neurostimulators.
* Cochlear implants.
* Internal irrigation pumps.
Currently, there are pacemakers, brain clips, and heart valves that are magnetic, and they must be properly evaluated before exposure to magnets.
Most implants and orthopedic prostheses do not have ferromagnetic properties and are compatible with magnetic resonance imaging.
APPOINTMENT
By appointment
SCHEDULE
Check the study schedule from Monday to Friday, 8 a.m. to 5 p.m.
PREVIOUS TESTS
You must bring specific previous studies (colonoscopy, biopsy) and laboratory results.
PREPARATION
Follow a residue-free diet for 4 days prior to the study (NO vegetables, cereals, or fruit)
The day before, at 6 p.m., drink one liter of Barex 70.
Continue with a liquid diet, avoiding anything that contains gas.
Administer an enema 3 hours before the appointment
Fast for 6 hours if the study is performed with IV contrast.
WHERE TO HAVE THE TEST DONE
