Magnetic resonance imaging (MRI) is a sophisticated, effective and non-invasive technique in the field of medical imaging. The integration of MRI in the clinical setting is a sign of significant advancement in diagnostic practices, eliminating the need for exposure to potentially harmful ionizing radiation.
An MRI scan provides detailed images of bodily structures and organs using magnetic fields and radio waves. Let us understand more about MRI, including its purpose, mechanism and risks.
The basics of MRI
MRI uses powerful magnets to generate a strong magnetic field, which interacts with the protons present in the body. Following this interaction, a transmitter emits radiofrequency pulses that continue to engage with these protons. Consequently, the protons emit a discernible signal, which is captured by a scanner and processed by the computer to create detailed cross-sectional images.
Purpose of MRI
MRI serves as the gold standard for detecting injuries in several body parts, such as the brain, skeletal system and soft tissues. It can be of several types, and they are selected based on the region of the body to be examined. Some common bodily structures that are examined with an MRI include:
Brain
A brain MRI (also known as cerebral MRI) aids physicians in detecting and analyzing a range of complications, such as abnormal swelling of the cerebral vessels, brain and spinal cord injuries, brain aneurysms, brain and spinal tumors, multiple sclerosis, nerve and spinal cord inflammation and strokes.
Cervical spine (neck)
A cervical spine MRI is employed to assess discomfort, numbness and tingling sensations in the arms, neck and shoulders. It's also utilized to detect tumors, bleeding, swelling or inflammation around the spinal cord.
Heart
A cardiac MRI assesses the anatomy and physiology of the heart's chambers, valves, vessel size and blood flow. It is also used to detect and monitor cardiovascular issues like tumors, infections, coronary artery disease and congenital heart conditions in children and adults.
Bones and joints
An MRI of the bones and joints helps determine bone tumors, disc abnormalities, bone infections and joint injuries.
Body
A whole-body MRI can detect structural changes and abnormalities in the body, including tumors in the abdomen, chest or pelvis. It also aids in the detection of hepatic conditions (such as liver cirrhosis) and inflammatory bowel diseases (like Crohn's disease and ulcerative colitis). Additionally, it is employed to detect abnormalities in the blood vessels and monitor fetal development.
What to expect during an MRI scan?
MRI report
The MRI report prepared by a radiologist interprets the images, highlighting any abnormalities or areas of concern. It serves as a valuable tool for healthcare professionals, assisting in accurate diagnosis and appropriate treatment plans.
MRI: Are there any risks?
While MRI has revolutionized the field of medical diagnostics with its safe and intricate mechanism, it is important to be aware of the associated risks, which are as follows:
Those who are fearful, have allergies or are concerned about health issues should reveal their apprehension to the radiologist. They will address any such issue and ensure the safety of the individual.
