MRIs are better for evaluating soft tissues such as tendon and ligament injuries, brain tumors or spinal cord injuries.
Is MRI harmful for brain?
Magnetic resonance imaging (MRI) of the brain is a safe and painless test that uses a magnetic field and radio waves to produce detailed images of the brain and the brain stem. An MRI differs from a CAT scan (also called a CT scan or a computed axial tomography scan) because it does not use radiation.
Do MRI have side effects?
There are no known side effects from an MRI scan. Patients with claustrophobia or anxiety may be given a sedative medicine to relax during the process and any medication can have side effects
Can MRI kill you?
MRI machines allow doctors to see inside your body and diagnose what’s wrong with you, but if mistakes are made, they can hurt or even kill you. “If administered properly, it’s one of the safest exams that have ever been invented,” says Tobias Gilk, an MRI safety advocate. But accidents do happen.
