MR Scan
July 3,2024 Update
Introduction to the examination room
MRI stands for Magnetic Resonance Imaging. There is also MRA (MR Angiography) which displays the blood vessels, and a test method such as MRS (MR Spectroscopy) which displays the spectrum of components in the biological material.
We have four MR devices(East MR1,East MR2,East MR3,MR4), so after reception at the automatic return visit kiosk on the 1st floor, please come to the Nuclear Medicine Scan and the MR Scan reception in the basement 1st floor. You will be directed to an examination room.
| Examination Room | MR Equipment |
|---|---|
| East MR Scan Room 1 | SIEMENS, MAGNETOM Avanto fit 1.5T |
| East MR Scan Room 2 | SIEMENS, MAGNETOM Skyra fit 3.0T |
| East MR Scan Room 3 | PHILIPS Ingenia 1.5T |
| MR Scan Room 4 | PHILIPS Ingenia Elition 3.0T |
Time for the examination
The examination will usually take 20-30 minutes, and a special examination will take about 1 hour. In addition, the time will vary greatly depending on the examination site and the examination purpose.
In addition to the above examination time, the device will make some loud noises. The device is very sensitive to movement so please do not move even though it might feel very loud.
Important Points
First, before receiving an MR Scan, there are contraindications that would make it not possible to undergo a MR Scan. Thank you for your confirmation of your condition, since these are also matters related to human life. We need to know if
- you have a surgical history where there was metal implanted in your body that is not compatible with MR (however, it is possible to carry out the procedure for surgeries that have been performed in our hospital since 1990).
- you have a device implanted in your body (cardiac pacemaker, defibrillator, cochlear implant). (In some cases, MRI examinations can be performed even if a cardiac pacemaker or surgical metal implants are implanted in the body. Prior confirmation is required, so please check with the requesting physician first.)
- you have tattoos or permanent cosmetics (risk of burns).
- you have magnetic dentures or orthodontic appliances.
(Please consult with the dentist who performed the procedure. The examination can only be performed if the patient agrees and accepts the possibility of burns and defects.) - you are pregnant or have a possibility of being pregnant (please consult with your requesting physician).
- you have an artificial eye which cannot be detached and is not compatible with MR.
- you are wearing moisture absorbing, heat generating fiber clothing (e.g. Heattech).
- you have decorations in the head and body hair, hair growth powder, color powder (including spray), temporary hair dye, hair manicure, mascara, etc. (Do not use the MRI scanner with decorations on the head and body hair, as such decorations may cause a malfunction of the MRI system, depending on the product).
Precautions before and after the examination are as follows:
< Before the Examination >
You will be asked to change into examination clothes and put your clothes in a locker (Please lock the locker and wait).
- Take off any clothing with metal attached (fasteners, hooks, etc.).
- emove any affixed medications (poultices, magnetic therapy devices (e.g., Ereki-ban) etc.).
- Remove jewelry and accessories (watches, necklaces, rings, glasses, etc.).
- Don't bring your wallet or cell phone into the room.
- Remove dentures, artificial eyes, etc.
- Remove contact lenses (color contacts are contraindicated for MR).
- Those who will have an MRCP that will be examining the gallbladder and pancreatic duct must fast for at least 4 hours before the test.
< After the Examination >
There are a few precautions when using a contrast agent.
- Although it is a very low possibility (less than 1 %), there is a possibility of side effects (headaches, rashes, vomiting, etc.), so try to excrete the administered contrast agent through the urine by drinking a lot of water.
- Symptoms such as soft stool or diarrhea may occur due to the effects of medications taken during an abdominal examination.
