PDF-Functional magnetic resonance imaging fMRI is becoming a popular noninvasive tool for

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.
