PPT-MAGNETIC RESONANCE (MR) SAFETY

Danger The Magnet is Always On Who Should Take This Course Individuals who frequent the MR area such as those who transport patients those who clean the area support assistants who help the Level 2 MR Technologists with getting patients onoff the table andor those who respond to emergencies in Zones III and IV of the MR area must take this course or an equivalent safety course . Principle first observed in 1946. Used for spectroscopy and imaging . Imaging techniques are a form of tomography, where slices are ’cut’ and depict. MRI utilizes signals from the body . MRI is non-ionizing, operating in radiofrequency range, unlike CT, PET, SPECT. David . J. . Keeble. Magnetic Resonance. Magnetic moments?. Magnetic. What matters is matter with moments.

It is not possible to see the internal organs and structure of the human body directly to locate the infection or illness . Magnetic resonance imaging (MRI) is a spectroscopic imaging technique used in medical setting to produce image of the internal structure of the human body. The scan uses a strong magnetic field and radio waves to generate images of internal parts ( cells, tissues , organs ) of the body that can't be seen as well with X-rays , CT scans or ultrasounds . For example , it can help doctors to see inside joints , cartilage , ligaments , muscles and tendons , which make it helpful for detecting various sports injuries. It is also used to examine internal body structures and diagnose a variety of disorders , such as strokes, tumors , aneurysms , spinal cord injuries , multiple sclerosis and eye or inner ear problems. It is also widely used in research to measure brain structure and their function.. Magnetic field safety. UCSB EH&S Radiation Safety Office. scope.
