PPT-Magnetic Resonance Imaging (MR)

Website wwwcertpotcom Certification Dump Prove Your Expertise in IT and Software Technologies. 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 Igor .
