| 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?

| Help |
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.

I am trying to get in contact with imaging ed for virtual courses. I have called, emailed etc with no response. Does this company still provide? Does anyone know of another way to contact them?

| Deaf in one ear but MRI scan says 'everything's normal' |
(I'm not a professional user of MRI, just someone who has recently had an MRI scan and is puzzled at the result. I hope it's still OK to post here).rnrnSeveral months ago I received a violent blow to the side of my head, and ever since, I have been totally deaf in the ear on that side. Even worse, instead of hearing anything in that ear, I'm getting a constant really loud whistling sound in that ear. As you can imagine, this is causing me a great amount of distress.rnrnI was given a CT scan which showed nothing, so then I was given an MRI scan, and I recently got the result. To my great surprise (and dismay) the letter i got from the specialist said that the scan showed that 'everything was perfectly normal'. My first reaction was to phone him and ask just how I could be totally deaf in one ear if the scan showed everything was normal, but I live in the UK, and you're not even allowed to approach a specialist directly - you have to get your doctor to do this for you. In view of how overstretched our health service is here, it could be months before I can get any answers.rnrnThis is why I'm posting here. I don't know anything about MRI scanners and all the Internet searches I've done just come up with answers to things like 'are they safe?' and 'how noisy are they?'rnrnSo can anyone tell me how an MRI scan can show there's nothing wrong with me when I'm totally deaf in an ear that had nothing wrong with it before that blow to the head?rnrnAny answers will be very gratefully received.

| Is It Illegal? |
You did not mention your state, and this would be covered by state law, not federal. I am not a lawyer but we sell and service MRIs all over the country. Almost certainly this is not illegal, however it is almost certainly in violation of your hospital's accreditation standards, and your hospital's insurance company would also be alarmed at this. Free advice--get a different job, this is a remarkably bad idea. Find an employer who believes in using qualified people to do their jobs.
