Excellent sources Scott - thank you. So I'll add these key points as differences between fMRI and PET:
PET: adv: patient can move during the scan, disadv: expensive and invasive (injection of radioactive isotope) fMRI: adv: higher resolution than PET, non-invasive, disadv: patient cannot move during the scanning process It sounds like it would be too difficult (and not necessary) for our students to be able to tell the difference between an image of an fMRI scan and a PET scan.
