Magnetic Resonance Imaging (MRI) allows for detailed visualization of organs and structures within the body. These images are obtained thanks to a magnetic field and pulses of energy.
The machine used for MRI is very big. In most cases, the examination is performed by a qualified technician, MRI specialist such as Best radiologist in Lahore, in a hospital or clinic that has such a machine.
When will the review be undertaken?
This examination is performed as needed when the doctor requests a detailed cross-sectional picture of the inside of the body.
As MRIs create detailed body images, doctors use them to detect problems in people with different symptoms or conditions.
MRI can be used to detect tissue damage, tumors, infections, or blood flow problems. It also helps to see blood clots, brain damage and nerve damage (as in the case of multiple sclerosis). MRI is also useful for detecting lesions of the heart and lungs, the genital tract, the bladder, bones and joints (such as arthritis), and the spine.
Sometimes the technician injects a special dye (also called a contrast agent, or contrast medium) into the arm. This provides a clearer picture of any damaged or abnormal tissue (especially blood vessels).
Risks and precautionary measures
The powerful magnetic field used during an MRI does not hurt or cause any injury to the body. Magnetic field and energy pulses do not cause cancer. However, the magnet can damage some pacemakers, artificial limbs and other medical devices made of metal. Loose metal objects (such as watches, jewelery, hairpins or dentures) must be removed before the examination or they will be quickly attracted to the magnet, which can cause serious injury.
There is a slight risk of allergic reaction to the dye to make the MRI images sharper. It is important to tell your doctor and the radiologist if you have any allergies, especially to contrast agents.
The contrast agent commonly used in MRI is gadolinium. If you have severe kidney disease, it is important to talk to your doctor and radiologist on Marham-Find a Doctor, as this contrast agent could cause serious skin disease in this situation.
Tell your doctor or the person performing the test if you have metallic objects in your eyes. The magnetic field could move the pieces of metal and damage the eyes. Since the effects of the MRI on the unborn baby are not known, tell your doctor or the person conducting the test if you are pregnant or if you may be pregnant.
If you take medicine in the form of patches, you should tell your doctor before starting the test. Patches that contain an aluminum film may respond to MRI and cause skin burns. This type of patch must be removed before the examination.
