What Does An MRI Diagnose?
Your doctor has probably prescribed an MRI for you or your loved one. You may have heard of it before but are confused as to what it is, what it involves and what purpose it serves. Read on to know more.
What is MRI?
MRI Imaging is a detailed, non-invasive method that helps to diagnose medical conditions that may escape other examination methods. Magnetic Resonance Imaging uses radio frequencies and magnetic field to scan the body.
The images of soft tissue, bones, and organs are then projected onto a computer screen. Unlike a CT scan or X-ray, it does not use radiation; so, it is a safer alternative. MRI produces more detailed and clearer images than a CT scan.
Uses
It is mainly used to examine organs in the abdomen, chest, lymph nodes and blood vessels. Such organs include the heart, kidney, spleen, bladder, breasts, and reproductive organs. It can be safely used on pregnant women. It is also used to monitor treatment.
MRI of the Brain and Spinal Cord
This is used to diagnose diseases such as brain tumors, cancer, brain and spinal cord injuries, stroke, and multiple sclerosis.
MRI of the Chest
This helps to diagnose heart-related conditions such as congenital heart disease, inflammation and malformation of blood vessels, and problems related to the structure of the heart.
MRI of the Abdomen & Pelvic Area
It is used to diagnose a myriad of health conditions including tumors, liver cirrhosis, inflammatory bowel syndrome, cancer, kidney disease, diseases of the reproductive health, and pregnancy-related issues.
MRI of the Bones
This type of MRI looks for bone and joint disease, cancer, as well as problems with the spinal disk.
Functional MRI (fMRI)
This type monitors brain activity to see which parts are active or inactive when you perform certain tasks. It helps to monitor the extent and effects of diseases such as stroke, epilepsy, and tumors.
The Procedure
Before the procedure, let your doctor know of any underlying condition such as kidney or liver disease, asthma, or allergies. Also, inform the technologist of any medical devices you may be wearing.
The MRI is a tube open on both ends and surrounded by a magnet. You will be placed on a table then rolled into the tube. If you have issues being in a confined space, you may undergo sedation to calm your nerves, or you may be placed in a semi-open tube.
MRI Imaging technology enables a detailed and accurate diagnosis of diseases of the brain, chest, bones, and abdomen. It is also used to monitor the progress of treatment. Successful treatment depends on an accurate diagnosis.
