What is an MRI?
MRI stands for Magnetic Resonance Imaging. It is a diagnostic process that uses a combination of radio frequencies, a magnet, and a computer for producing detailed images of structures and organs within the body. Unlike CT scans and X-rays, it does not use ionizing radiations. MRI scans can last from about 30 minutes to two hours.
Reasons behind an MRI of the brain
A mri brain scan in New Jersey is used to examine the brain for the presence of structural abnormalities or injuries or any other conditions like:
- Abscesses
- Tumours
- Aneurysms
- Subdural hematoma
- Congenital abnormalities
- Haemorrhage
- Venous malformations
- Hydrocephalus
- Degenerative diseases, hypoxic encephalopathy, multiple sclerosis, encephalomyelitis
- Degeneration of the discs of spinal cord
- Planning of surgeries on the spine (such as spinal fusion or decompression of a pinched nerve)
MRI can also assist in identifying a specific location of the functional centre of the brain, which is that specific part of the brain that is responsible for controlling a function such as memory or speech. This assists in the successful treatment of the brain.
How to effectively prepare for an MRI?
During a mri brain scan in New Jersey, you can prepare yourself by considering the following a few points:
- Clothing
One is required to change into a patient gown and lock up all the essential personal belongings. Also, one should remove all the piercings and leave all the valuables and jewellery at home.
- Eating and drinking
A person might drink, eat, and take various medications as usual for most MRI exams, but certain speciality MRI exams follow restrictions. One can be provided with a detailed preparation list by Johns Hopkins Medical Imaging while scheduling an exam.
- What can be expected
Imaging always takes place inside of a large tube-like structure that is open on both ends. For quality images, one must lie perfectly still for the stipulated period. Earplugs are provided and needed because of the loud noise produced by MRI machines.
- Strong magnetic environment
If you have the presence of metal inside your body that was not successfully disclosed before your appointment, your specific study might be delayed, cancelled, or rescheduled upon your arrival until any further information is obtained.
