An introduction to the physics and engineering of MRI are described here by MR physicist Rasmus Birn. For more info/content, please visit: postlab.psych....
after so many youtube’s videos and even going through my lecture slides and rewatching the lecture video, I FINALLY understand MRI! thank you for these clear steps of how it works sequentially!! God bless you
Thank you, thank you, thank you. The other MRI videos neglect to answer how the MRI is able to determine/localize and "see" and measure the energy at those specific areas/point to build up a full image. That part baffled me, but this video answered it perfectly. Thank you again.
A late reply- you probably have the answer already! it is gadolinium, a paramagnetic element, they use for contrast. It changes the T1 and T2 parameters of the hydrogen atoms in water, and this allows sharper images of certain organs. Iodine is used for x-rays as it can absorb a band of x-ray energy below about 50keV.
I had an MRI done couple years back and that thing is so loud, the doctor stuffed ear muffs/pillows between my head and a frame (the coil I assume), and it still felt like I was in an 8D sound concert of knocking and sawing. If that's how auditory hallucinations feel like, that's scary
