Welcome! In this course learners will develop expertise in basic magnetic resonance imaging (MRI) physics and principles and gain knowledge of many different data acquisition strategies in MRI. In particular, learners will get to know what is magnetic resonance phenomenon, how magnetic resonance signals are generated, how an image can be formulated using MRI, how soft tissue contrast can change with imaging parameters. Also introduced will be MR imaging sequences of spin echo, gradient echo, fast spin echo, echo planar imaging, inversion recovery, etc.

Great Course that covers quite a lot on the ins-and-outs of MRI technology, though it doesn't cover fMRI. Despite that fact, it's a definite course to try out if you were curious of how MRIs work.
thank you for the great information you have gifted
