Precautions to Be Taken Before and During Magnetic Resonance Imaging Scan
Magnetic resonance imaging (MRI) is a medical imaging technique used primarily to produce high quality detailed images of the inside of the human body.
This medical imaging technique is based on the principle of nuclear magnetic resonance (NMR), a spectroscopic technique used by scientists to gather microscopic chemical and physical information about molecules.
Magnetic resonance imaging started out as a tomographic imaging technique, to produce an image of the NMR signal in a thin slice through the human body.
Magnetic resonance imaging uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed images of organs, soft tissues, bone and all other internal body structures of the body.
Signs of arterial sclerosis in the heart can be detected by this method.
In the spine, bones, and joints it can find ruptured disks, torn cartilage, and tumors.
MR imaging of the body is performed to evaluate blood vessels, pelvic organs including the reproductive organs in the male (prostate and testicles) and the female (uterus, cervix and ovaries), breasts and organs of the chest and abdomen including the heart, liver, biliary tract, kidneys, spleen, pancreas and adrenal glands.
During the examination, patients may require swallowing contrast material or they might receive an injection of contrast into the veins to enhance the appearance of blood vessels, tumors or inflammation.
If the patient has allergies of any kind such as allergy to iodine or x-ray contrast material, drugs, food, the environment, or asthma, you need to inform the doctor in advance.
Often doctors use the contrast material called gadolinium that does not contain iodine and is less likely to cause side effects or an allergic reaction.
If you are having any serious health issue or have undergone surgery, do inform the radiologist about it.
In such cases, doctors may prevent you from giving a contrast material for an MRI.
Especially if you are suffering from kidney disease, you may need to perform a blood test to find out whether the kidneys are functioning adequately or not.
Patients with metal implant should inform the doctor beforehand.
Women should inform doctors if they are pregnant.
Although there is no evidence of ill effect on pregnant women or their babies, but it is better to avoid this test during pregnancy because, the baby would be exposed to strong magnetic field.
Jewelry and other accessories should be removed prior to the MRI scan because they can interfere with the magnetic field of the MRI unit.
These are some of the precautions to be takes before and during the MRI scan.
