Magnetic Resonance Imaging (MRI) service.
Magnetic Resonance Imaging or MRI is a medical imaging technique that uses computer-generated radio waves to stimulate the intended organ needed to be examined and to measure hydrogen energy levels within the body which is also known as resonance. Then it is generated into an image and is more detailed than a CT scan because it can identify the different types of tissues, enable multiple planes, create 3D images and can be used to detect all systems of the body especially in the brain. For example when checking for tumors in the brain, the nervous system or the spine. There are more specific techniques for patients with an acute ischemic stroke, analyzing biochemistry levels to determine lump types or checking blood vessels throughout the body etc.
Preparation prior to the procedure.
1. No water and food for 6-hours before the procedure for patients doing an upper abdominal examination (Liver + <R Elastography), duct and gallbladder examination (MRCP), Cardiovascular Stress Monitor (MRI) and pediatric patients requiring Anesthesia.
2. If the patient falls into one of the following categories, please inform the staff when making an appointment or immediately before the examination.
- Pregnant women or unsure if pregnant.
- Patients that are allergic to radiation substances.
- Patients that are allergic to medical drugs.
- Patients that have a history of allergies, asthma, or epilepsy, etc
3. Patients must have kidney function results (Creatinine) before the examination no more than 3 months old.
4. Patients should avoid bringing metals such as jewelry, electronic devices, mobile phones, watches, credit cards, key chains, coins, or other metal things which may have been ingested into the radiation examination room. Ladies should wipe off cosmetics before entering the examination room, especially eye shadow and mascara because they contain metal.
- Patients are required to stay as still as possible for optimal image quality which will lead to a more precise diagnosis and reduce the time of the procedure. A radiologist will provide assistance in arranging positions. Patients should refrain from talking while the MRI is on.
- Patients undergoing abdomen or heart testing will be required to hold their breath with the guidance of a medical professional before and during the procedure to reduce the movement of internal organs.
- If intravenous MRI contrast agents are needed to help enhance specific areas, patients will be informed before the scheduled appointment.
- After the examination, patients may eat and drink as normal.
