Dr. Don Wood explains how SPECT scans show brain blood flow and activity where MRI only reveals structure. He trained at Dr. Daniel Amen's clinics, which lead the field, and discusses using SPECT to identify functional signatures of anxiety.

Doctor Amen has a number of clinics around the country called Amen Clinics and he specializes in SPECT scans. Now, SPECT scans aren't cheap, unfortunately. You know, depending on where you go and what you do, cost money to have a SPECT scan. But the reason I wanted to get a SPECT scan and they kept saying, well, the MRI looks fine. Well, the MRI is showing the structural issues. What we needed to see was the fine functioning, what's the blood flow, how's the brain functioning. And Dr. Amen is probably the leading person in the world, at least the country for sure, if not the world, on doing SPECT scans. And what a SPECT scan basically does is measures the brainwave activity inside the brain. So I've done, I've been certified with Dr. Amen through his clinics as well. So what Dr. Amen is able to do when they do a SPECT scan, if somebody has anxiety, it will show up in brainwave activity.
