MRI – 3T
What is it?
Magnetic Resonance Imaging (MRI ) is an advanced diagnostic imaging technique that produces high resolution, computerised images of the human body, sometimes in 3D. These images are photographed on film and are either accessible via the internet or burned onto a CD. These are reported by an MRI specialist radiologist before being sent to your referring doctor. MRI scanning does not use radiation and is a painless procedure.
At Bridge Road Imaging, we have two 3T MRI scanners with a 70cm bore (width of tunnel). This is the largest bore size available.
3T is the highest field strength MRI in clinical practice in the world. 3T refers to the strength or power of the magnet inside the machine. The higher the field strength, the more signal is produced. This matched to our ultra -high density coils (our head coil has 64 channels) allows us to acquire the highest resolution images in the shortest amount of time.
This directly improves the patient experience with less claustrophobia and the best quality images.
We also perform specialty MRI sequences including MR Spectroscopy and MR Perfusion, these are extremely useful in the diagnosis and response to treatment of brain tumours.
Is MRI for Everyone?
Unfortunately not everyone is able to have an MRI Scan. Some implants, including pacemakers and cochlear ear implants, exclude individuals from undergoing MRI.
What to tell us?
If you experience high levels of anxiety or claustrophobia or you have any metal or surgical implants.
If you have had metal in your eyes at any time during your life and have not had a MRI scan before, an X-ray will be taken by our staff to ensure that no metal remains. Should metal be detected, it will need to be removed by a doctor prior to having a scan. Metal within your eyes may cause permanent eye damage to due to the high magnetic field of the MRI scanner.
How to Prepare?
No specific preparation is required. You may eat and drink normally and take your usual medication. If you are taking medication for pain, we advise that this is taken prior to the scan as it is important to remain still throughout the examination. Jewellery and makeup cannot be worn whilst having an MRI scan.
What does the procedure involve?
For the examination you will be asked to lay on a padded examination table that slowly glides into the scanner. You will be positioned comfortably, generally with your arms at your side.
The MRI scanner is well lit and remains open at both ends. Air consistently circulates around you during the examination. The scanner makes a series of loud banging noises and there will be a small amount of vibration while the images are being collected. The technicians will provide you with some ear plugs or headphones with music of your choice and they will be in constant contact with you during the test.
You must hold very still and may be asked to keep from breathing for a few seconds while the images are being taken to reduce the possibility of a blurred image.
How long will it take?
MRI procedures can take up to 30 minutes depending on the body part being scanned.
