Question 13: FMRI is a rapid MR technique that acquires images of the brain during an activity or stimulus and at rest. The most important physiological effect that produces MR signal intensity changes between a stimulus and a rest is called Blood Oxygenation Level Dependence (BOLD). Which pulse sequence is used in FMRI specifically because BOLD effects are very short lived?
