Magnetic Resonance Imaging (MRI) is designed to produce detailed images of internal organs using a magnet field, radio waves and a computer.
MRI is useful in discovering minor changes inside the body, crucial for an early diagnosis. It is suitable for imaging any part of the body (such as the bones and soft tissues) without involving X-ray radiation.
Contrast agents
In some cases, we need to view some tissues and blood vessels clearly by using a contrast agent.
The contrast agent is made by gadolinium, which is less likely to produce an allergic reaction compared to the iodine-based materials used for X-rays and CT scan. It is very rare to experience an allergic reaction. Medication can be used to control mild symptoms, while serious reactions are very unlikely.
Nephrogenic systemic fibrosis (NSF), a rare complication, occurs when gadolinium-based contrast agents are provided to patients with severe kidney disease. Therefore, this contrast is prohibited in these cases. Please inform radiographer if you are suffering from kidney diseases.
Points to note post-screening
In most cases, you will be able to go home on your own after completing the scans. If you have taken sedatives, however, you are not advised to drive, drink alcohol, or sign any formal document within 24 hours. We would advise you to be accompanied by a friend or family in this case.
Your radiographer will send the film and written report to you when they are ready.
