MR imaging

Magnetic resonance imaging is probably one of the hardest subjects to understand in radiology physics, probably because most of the concepts are oversimplified, in the same way that in A-level chemistry you learnt that your GCSE chemistry, whilst a good approximation to the truth, is oversimplified.

If you want to get to the "truth", then you'll need a big textbook. However, I'll be focusing on what you need to pass the exam.

The first section of this chapter covers a little on the MR machine and the various magnets and coils as this will make it easier to understand the axes and how the transverse magnetisation is produced. Then the "Introduction to MRI" is a chapter on the basic physics of MR needed to understand everything else. I've subsequently separated out the pages based on the way I found it easiest to work through and understand i.e. I haven't included all the sequences in one chapter.
