Hi Max, I'm just going to cover the question about
an MRI via my own experiences.
MRIs are noninvasive and does not use ionizing radiation which are used in x-rays and CTs (computed tomography).
MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs and essentially all other internal body structures. They're high contrast images of intestinal inflammation, abscesses and fistulas in the small bowel. (if they're present) It may also help to distinguish active disease from inactive disease.
A great thing about
an MRI is that the images taken can be examined on a computer monitor and burned to a DVD/CD.
eating and drinking before an MRI exam vary with the specific exam and also with the facilities protocols.
Prior to receiving an MRI you will be asked if you have allergies of any kind. (drugs, food, contrast material) You will also be asked about
health problems or if you recently had surgery.
You will be asked to wear a hospital gown, most likely since it will be for a small bowel series, drink two cups of a water solution mixed with a contrast material. A Technologist will insert an IV into a vein in your hand or arm. A saline solution may be used, the solution will drip through the IV to prevent blockage of the IV catheter until the contrast material is injected.
Either before or after the IV is inserted, you will be on a moveable examination table. Once everything is all ready, the examination table will slide into the MRI unit and the Technologist will leave the room while the MRI examination is performed. Sometimes the contrast material will be injected into the IV after an initial series of scans. You may feel a warm sensation throughout your body and a need to pee but it doesn't last long.
The MRI unit may seem like a very tight fit once you slide into the unit on the table, if you suffer from claustrophobia, you can request a mild sedative.
You will be alone in the room during the MRI procedure but there's a two way intercom (headphones) and the Technologist will be able to see, hear and speak with you.
It is important that you remain still while the images are being recorded, which is usually only a few seconds. Where I have had my MRIs, commands given about
holding your breath, exhaling, relaxing are from an automated voice. You will definitely know when images are being recorded because you will hear thumping sounds, it can rather loud and drown out music that they can play for you. You can also request earplugs, personally I have never requested them.
There is also a call button to speak with the Technologist, for people who do suffer from claustrophobia and having a very difficult time.
I've had MRIs last up to 45 minutes, sometimes a bit less. I just relax and close my eyes while in the MRI unit. Probably the hardest thing to do, is to remain still.
People have different reactions to the contrast material that you will have to drink. Meaning quite a few visits to the bathroom.
