reHealth Comprehensive MRI Health Check for Stroke Prevention
Includes examination of the brain, cerebellum, brainstem, eyeballs, nasal cavity, sinuses, middle ear, inner ear and more. Detect and assess early signs of cerebrovascular diseases such as microembolism, brain tumors, cerebrovascular abnormalities, hemangioma, cerebral atrophy, and brain parenchymal lesions.
For your safety, please inform our medical staff before the MRI scan if you:
-have a cochlear implant
-have an IVC filter
-have a Swan-Ganz catheter
-have an insulin injector
-have an internal electrode or stimulator
-have a nerve stimulator
-have an implantable drug delivery devices, stent, vessel clip
-have used astrictive steel wire, or steel plate, and steel nail to immobilise or install artificial joints
-have metallic dentures or dental prosthetics (artefacts may form which affect the evaluation)
-are at early pregnancy (3 months or below)
-have claustrophobia
What is the principle and purpose of MRI?
Magnetic Resonance Imaging (MRI) employs a strong magnetic field that forces protons in the body to release electromagnetic waves to create detailed images of the inside of the body. MRI is non-radioactive and therefore is suitable for a check-up, diagnosis, and follow-up of most body parts (including the musculoskeletal, and the nervous system). MRI is more commonly used for examination of the brain, spinal nerves, ligaments, joints, muscles, heart, blood vessels, breasts, abdomen, etc. It is also used to monitor changes in fatty liver and the progress of cartilage repair.
Are there any side effects to getting an MRI? Is it radioactive?
MRI scan is an imaging scan that utilises a magnetic field and resonance frequency. With the generated strong magnetic field, the hydrogen particles inside the human body are realigned to exhibit distinctive magnetic resonance. Different from x-ray and CT scan, MRI is not radioactive.
What is the purpose of injecting a contrast agent prior to an MRI scan?
If necessary, a contrast agent will be injected to allow blood vessels and abnormal tissue to be easily visualised. There is no weird sensation upon injection. The possibility of having allergic and biological reactions is low.
