The MRI system utilises magnet with a high field super-conducting system and radio-frequency pulses to examine the body’s internal organs. It is a technique of choice for imaging of the brain, spine (Central Nervous System), musculoskeletal region and heart. Magnetic resonance imaging (MRI) is a safe, non-invasive test that creates detailed pictures of your organs and tissues. This means that no surgery is done and no instruments are inserted into your body.
The devices or conditions listed below might prohibit you from having an MRI examination. If you have any of these devices, make sure your physician and the MRI staff are informed:
- Artificial heart valves
- Metallic clips used in brain surgery
- Implanted hearing aids
- Metal implants
- Metal shrapnel in your body
- Metal fragments in your eyes
- Intra-uterine contraceptives devices
No radiation is involved in this procedure. KPJ Klang uses 1.5T (SIEMENS-Magnetom Avanto) to create detailed pictures of organs and tissues such as:
- Cysts, brain aneurysms, stroke, tumors and cancer throughout the body.
- Blockages or enlargement of blood vessels and certain heart and aorta problems.
- Diseases of the liver, gallbladder, pancreas and other abdominal organs.
- Abnormalities and diseases of the reproductive organs, including the causes of infertility, in both women and men.
- Spine injuries, disorders or inflammation of the spine. Neurosurgeons also can evaluate the integrity of the spinal cord after trauma. It is also used when considering problems associated with the vertebrae or intervertebral discs of the spine.
- Diagnostic or evaluation for any extremities such as:
- Degenerative joint disorders such as arthritis and meniscus tears (knee) or labral tears (shoulder and hip)
- Fractures (in selected patients)
- Joint abnormalities due to trauma (such as tears of ligaments and tendons)
- Spinal disk abnormalities (such as a herniated disk)
- Spinal cord integrity upon trauma
- Sports-related injuries and work-related disorders caused by repeated strain, vibration or forceful impact
- Infections (such as osteomyelitis)
- Tumors (primary tumors and metastases) involving bones and joints
- Pain, swelling or bleeding in the tissues in and around the joints and extremities
Cardiac MRI creates both still and moving imaging of your heart and major blood vessels. Doctors use cardiac MRI to get imaging of the beating heart and to look at its structure and function. Cardiac MRI is commonly used to diagnose and assess many diseases and conditions, including:
- Coronary heart disease
- Damage caused by a heart attack
- Heart failure
- Heart valve problems
- Congenital heart defects (heart defects present at birth)
- Pericarditis (a condition in which the membrane, or sac, around your heart is inflamed)
- Cardiac tumors
The scan usually takes about 30 to 45 minutes. Usually there are no effects.You are free with your normal day plan once the scan is complete. There is avery small risk of allergic reaction related to the contrast medium (gadolinium chelate) injection. The scan is performed by a team of radiographer, a nurse, under the supervision of cardiologist (heart specialist) and radiologist.
