MRI
What is a MRI?
A magnetic resonance imaging (MRI) scan is a medical imaging technique that uses a magnetic field and radio waves to produce detailed images of the inside of the body. It is particularly useful for looking at soft tissue structures such as the brain, muscles, and internal organs. Unlike X-rays and CT scans, MRI does not use ionizing radiation, making it a safer option for many diagnostic procedures. It is non invasive imaging modality.
Book an AppointmentWhat to expect during an MRI?
During an MRI, the patient is placed on a table that is then moved into a large cylinder-shaped machine. The machine generates a strong magnetic field and radio waves, which produce detailed images of the inside of the body.
The procedure is painless, but can be loud due to the machine's noises. Some people may be given earplugs or noise-canceling headphones to wear during the scan. The technologist will also be in separate room controlling the machine, but able to communicate with you through intercom.
Depending on the type of MRI, you may be given a contrast agent, which is a substance that is injected into a vein to help certain areas of the body show up better on the images.The entire procedure usually takes around 30 minutes to an hour, but the actual scanning time may be shorter than that.
It is important to inform your doctor if you are pregnant or have any metal inside your body such as pacemaker or artificial joint, as this may affect whether an MRI is safe for you.
Here are some general guidelines for preparing for an MRI:
Wear comfortable clothing: Avoid clothing with metal zippers or buttons, as they can interfere with the magnetic field. You may be given a gown to wear during the procedure.
Inform your doctor of any metal in your body: Let your doctor know if you have any metal in your body, such as a pacemaker, cochlear implant, or aneurysm clips. Depending on the location and type of metal, the MRI may not be safe for you.
Remove jewelry and other metal objects: Remove all jewelry and any other metal objects you may have on your person, such as hairpins, glasses, and hearing aids.
Tell your doctor about any allergies or medical conditions: Inform your doctor about any allergies or medical conditions you have, particularly if you are allergic to contrast agents, which are often used during an MRI.
Inform of pregnancy: If you are pregnant, be sure to let your doctor know as the MRI may not be safe for the developing fetus.
Arrange transportation: Since you will need to lie down during the procedure, you will not be able to drive yourself home afterwards. Make arrangements for someone to take you home or consider public transport.
Following these guidelines can help ensure a safe and successful MRI procedure. Be sure to follow any additional instructions given by your doctor or the imaging center.
Screen Area
An MRI machine can scan virtually any part of the body that can fit into the bore (the opening) of the machine. The most common areas of the body that are scanned using MRI include:
Brain and spinal cord: MRI is particularly useful for imaging the brain and spinal cord because it can produce detailed images of soft tissue structures without using ionizing radiation.
Joints: MRI is often used to assess joints such as the knee, shoulder, and hip for injuries or degenerative conditions such as osteoarthritis.
Muscles and tendons: MRI can be used to evaluate muscles and tendons for injuries or tears.
Abdomen and pelvis: MRI can be used to image the internal organs of the abdomen and pelvis, such as the liver, kidney, and pancreas, as well as to assess for tumors or other abnormal growths.
Breast : Breast MRI is used as an adjunct to mammography, primarily for women at high risk of breast cancer or for those with dense breast tissue.
Heart and blood vessels: Cardiac MRI can be used to image the heart and blood vessels, and is particularly useful for assessing for conditions such as heart disease, aortic aneurysms, and blockages in the coronary vessels.
