Proton excitation from B0 to B1
I'm new to MRI imaging and currently taking an introductory course online. I understand that the introduction of a small magnetic field/RF pulses on top of the static magnetic field (B0) excites protons into a high energy state (B1). Does this mean that the protons are excited from a spin that is parallel to the longitudinal B0 plane to one that is antiparallel to the longitudinal B0 plane, or that the proton spin is excited from one that is aligned/polarized with B0 to one that is either parallel or antiparallel to B0 in the B1/xy plane?

This is the MRI in question. The eyes look different and I was not sure if this looked like Optic Neuritis.

Hello, I have been having extreme eye pain with visual disturbances which include flashes of light and sometimes double vision. I was told that my brain MRI was squeaky clean. However, out of curiosity, I looked at the images and found this one image that didn't sit right with me. I know it could mean nothing, but I was hoping to either get an answer or reassurance that everything really is ok. Thanks in advance to anyone willing to help.

Hi, You may start with checking the MRI candidate sites whether their MRI is equipped with following package: IDEAL IQ for GE MRI scanner, mDIXON-Quant for Philips MRI scanner, LiverLab for Siemens MRI scanner. This shall shall exclude some candidates and save a lot efforts. Certainly there will be other concerns if it's a multi-center study. This article may help: https://www.birpublications.org/doi/pdf/10.1259/bjr.20170378
