No preparation is necessary for an MRI scan. You can eat and drink normally. Though some discomfort may occur from having to lay still, MRI is otherwise a painless procedure. A MRI scan typically takes approximately 20 to 30 minutes to perform.
The test usually takes 30 to 60 minutes but can take as long as 2 hours.
A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.
The scan may last between 15 and 90 minutes, depending on how many images of the brain are needed.
Although the total cost of an MRI scan varies depending on the part of the body being imaged, costs generally range from $300 and $1,000.
For services listed on the Medicare Benefits Schedule (MBS), Medicare covers some or all of the costs of: CT scans. nuclear medicine scans. MRI scans.
Who can refer me for an MRI? In Australia, all primary health care practitioners can refer people to have MRI scans. This includes general practitioners [GP], chiropractors, physiotherapists, osteopaths, podiatrists, dentists, and medical specialists.
Generally, MRIs under anesthesia are performed under sedation, although sometimes they are performed under general anesthesia. Sedation is characterized as being in a state between relaxed and very sleepy, but not quite unconscious.
Brain MRIs usually take between 12 and 20 minutes to complete, whereas a breast MRI can take up to 45 minutes. MRIs take a long time to complete because they take many hundreds of images of your tissue in slices. They then build this up into a three-dimensional representation that doctors can study.
How long does an MRI scan take? A single scan may take a few seconds or 3 to 8 minutes. You may be asked to hold your breath during short scans. The total scan lasts 15 to 90 minutes, depending on the size of the area being scanned and how many images are needed.
On average, brain and spine exams may last about 45 minutes. If exam includes contrast, study may take up to 15 minutes longer. Body exams may take up to 45-60 minutes. For body exams, it is important to follow the breathing instructions given to you for good quality reading.
Radiologists at Massachusetts General Hospital, Boston have conducted the longest and most detailed MRI scan in history. By placing a brain into an MRI scanner for an impressive five days, they have managed to achieve a resolution as high as 0.1 millimeters.
You will be in constant communication with the MRI technicians and you can stop the scan at any time. We have a fan in case you get warm, blankets in case you are cool and bolstering pillows to help you stay comfortable during a long scan.
You must lie very still during the scan. If you move, the MRI scan pictures may not be clear. Your primary care physician may order you a mild sedative if you are claustrophobic (afraid of closed spaces), have a hard time staying still, or have chronic pain.
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
3T MRI is the fastest diagnostic magnetic resonance imaging technology available. The computer generated images can be sent off-site for immediate analysis. These exams can be up to 100 times faster than standard MRI exams. Another advantage of 3 Tesla MRI is that the exams offer more comfort than typical MRI exams.
A 5-minute, ultra-fast MRI can identify and diagnose intracranial abnormalities as effectively as a head CT, making it a good alternative for some patients with neurological emergencies.
A brain MRI can help doctors look for conditions such as bleeding, swelling, problems with the way the brain developed, tumors, infections, inflammation, damage from an injury or a stroke, or problems with the blood vessels. The MRI also can help doctors look for causes of headaches or seizures.

“Buying and installing an MRI scanner typically costs more than $2 million (AUD). This is why the machines are primarily found in imaging clinics and are unaffordable for medical centres in remote areas with small patient populations,” said Dr Waddington.
Medicare and health insurance won't cover MRI scans that are classified as outpatient services. However, both can cover you if you're admitted to hospital and require an MRI scan during the course of your treatment.
