A spectroscopic technique that provides information about the carbon-hydrogen framework of a molecule.. 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.

MRI(Magnetic Resonance Imaging). Radiation Safety (SEC). SUBJECT CODE – PHYS307TH. Magnetic Resonance Imaging (MRI). 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.. Spectroscopy. Learning Module #1. - The Electromagnetic Spectrum and Radiation.
