Could this be used for images other than people's brains?

I looked at this neuroscience course, and overwhelmingly it was a course on Fourier transforms and Radon transforms

Momentarily, I was asking myself why such a difficult math course is being given in the Psychology department

certainly, diffusion imaging is common in analysis of many physiologies including breast and prostate. It forms one of the sequences in multiparametric MRI which has had some recent success in improving the diagnosis of prostate cancer [1].

I'm also aware of at least one upcoming trial of full (or mostly full) body diffusion imaging to look for sites of metastasis. The trial is still in planning so unfortunately no link to share for that one.
