Your lectures made MR physics pretty much understandable . Thank you sir for making it simple

This was a great presentation, live. However, the VERY low resolution video submitted to KZbin (360!) obfuscates most of the artifacts discussed. Any KZbin presentation of image quality should be of a higher quality than the artifact examples, in order to observe the faulted against ideal examples.

I would be interested to hear which artifacts interfere with a doctor’s diagnosis and which are just an annoyance that is ignored. I am a retired engineer not from the medical field who has found this lecture series extremely interesting.

@Carlam 666 In India all artifacts diagnosed by Engineer only. Technologicst only report that they are getting not good images in MRI.

Dear sir, i am a MRI technologist work in a hospital at Dhaka, Bangladesh. Your lectures improved my knowledge on MRI so much. Thank you for your valuable lecture and who upload it in youtube. In my parctice i observed that there is too much noise/grainy artifacton image in gradient or, Haste images during the lights of mr room turned on. And scan after turning lights off, the noisiness or grain in image gone, so there is improvement of SNR a lot. Is this a artifact? How lights can effect noise in image, can you explian this? I am working on siemens magnetom aera 1.5T MRI scanner.

That is herringbone artifact because of RF interfearance. The alternate current of the filament of some lamps emit radiofrequencies that can be recieved by the mri's antenna.

Hi wonderful presentation. Can I ask if cross talk, cross excitation and slice overlap artifacts are the same?

The chemical shift artifact is not well explained۔ other wise Good explanation.
