Traditionally clinical imaging exploits the contrast due to differences in spin density spinlattice relaxation T and spinspin relaxation T between normal tissues and pathology However other contrast mechanisms such as susceptibility magnetization The commonest method of fMRI is blood oxygenation leveldependent BOLD imaging which has dominated this field since its discovery 1 BOLD fMRI employs haemoglobin as a convenient endogenous contrast agent relying on the magnetization difference betwee Department of Chemistry.

Introduction It has long been known that there is some degree of localization of function in the human brain ++. 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.. Magnetic field safety. UCSB EH&S Radiation Safety Office. scope.
