Magnetic Resonance Imaging (MRI) is a medical imaging technique used to produce detailed images of the internal organs and structures of the human body. It is a non-invasive, safe, and painless procedure that uses powerful magnetic fields and radio waves to create detailed cross-sectional images of the body. MRI scans are commonly used to diagnose diseases such as cancer, stroke, brain tumors, multiple sclerosis, and many other illnesses.
What is Magnetic Resonance Imaging?
Magnetic resonance imaging (MRI) is a type of imaging that uses powerful magnets and radio waves to create detailed images of organs and structures inside the body. MRI scans are non-invasive, safe, and painless procedures that can provide valuable information about what’s happening inside the body without exposing patients to radiation.
How does MRI work?
MRI works by sending strong magnetic pulses through the body that cause its hydrogen atoms to align in one direction. Radio waves are then sent at a specific frequency which causes these atoms to spin in different directions. This creates a signal which is then picked up by special detectors in an MRI machine and converted into an image.
Is MRI safe?
Yes. MRI scans involve no radiation exposure or any other type of risk associated with diagnostic imaging methods such as X-rays or CT scans. The only potential risks associated with MRI are from prolonged exposure to the strong magnetic field used during the scan, but these risks are minimal.
What can MRI be used for?
MRI can be used for diagnosing many medical conditions including cancer, stroke, brain tumors, multiple sclerosis, heart defects, joint problems, ligament tears and more. It can also be used for monitoring the progress of treatments such as chemotherapy or radiation therapy for cancer patients. Additionally, it can be used for diagnosing fetal abnormalities during pregnancy or examining blood vessels in the brain or neck area for signs of stroke or aneurysm.
Does any preparation need to be done before having an MRI?
Most people do not need any preparation before having an MRI scan; however, some individuals may need to avoid eating or drinking certain foods several hours prior to their appointment time depending on what type of scan they’re having done. Your doctor will provide you with specific instructions if you require any special preparation before your scan.
