The science underlying brain SPECT imaging | Dr. Daniel Amen

Many of you have been asking... what is a SPECT scan? It’s a brain imaging tool that shows blood flow and activity, helping our doctors diagnose more accurately and personalize treatment. To make this possible, a safe, tiny amount of isotope (similar to a CT scan) is given during a cognitive assessment. Why then? Because it captures the brain while it’s working. Then it’s scan time. The key? Stillness. Brian used his 20 minutes to sneak in a quick catnap — no movement means a clear, accurate sca

Risks of CT Scans New research shows that CT scan radiation may be responsible for 1 in every 20 cancer cases in the U.S. That’s over 103,000 cancers per year—from the very machines used to detect disease. Most people have no idea these scans come with ionizing radiation strong enough to damage DNA. And when multiple scans are done—especially on children—the risk skyrockets. Some estimates show up to 20 cancers per 1,000 scans for kids under 1. Safer options (if applicable): MRI Ultrasound Full-
