Magnetic Resonance Imaging (MRI) allows your doctor to analyze certain type of tissues and provides important information about the brain, spine, joints, and other internal organs. It facilitates early detection of diseases or injuries so the required treatment may be administered at the earliest.
How does it work?
While undergoing an MRI scan, you are placed in a strong magnetic field, which allows the acquisition of images that are a “slice” of the anatomy by rearranging the hydrogen atoms of the water molecules in the body in all 3 planes.These images are then processed using a computer to produce detailed pictures of the anatomy.
What precautions are required when undergoing an MRI?
Some metals (containing iron) interfere with the MRI machine, distorting the image produced during the scan. The patient is requested to hand over any such belongings to their attendants or place them in a locker provided at the premises.
There are two absolute contraindications associated with MRI imaging:
● Cardiac pacemakers
● Cochlear implants
How long does the process take?
The investigative procedure ordinarily takes between 15 to 30 minutes. If your doctor prescribes your MRI exam with contrast, the scan may take longer to complete.
What is contrast?
The contrast is a fluid that aids in making certain details on the MRI scan clearer and is routinely prescribed by practitioners. MRI scans with contrasts are not routinely prescribed to pregnant women.
When do I get my reports?
You can obtain the test reports the same evening.
Is there anything else I should know?
You are requested to bring a copy of the medical history of the patient, including recent lab work reports and any previous imaging scans that may have been prescribed by your doctor.
