The crowned dens syndrome. Evaluation with CT imaging. Biomechanical Considerations for Stabilization of the Craniovertebral Junction fMRI is based on the same technology as magnetic resonance imaging (MRI) -- a noninvasive test that uses a strong magnetic field and radio waves to create detailed images of the body. But instead of creating images of organs and tissues like MRI, fMRI looks at blood flow in the brain to detect areas of activity. در کنار fMRI امروزه از Electroencephalograph و همچنین از الکترودهایی که در مغز و به صورت تهاجمی قرار داده میشوند نیز برای برررسی نحوهٔ فعالیت آن استفاده میشود، که هر کدام مزایا و معایبی دارند. fMRI یک نوع تخصصی شده ازاسکنهای MRI Funksjonell magnetresonanstomografi (fMRI) er en funksjonell hjerneavbildningsteknikk som kan fremstille endringer i aktivitet i områder i hjernen til mennesker eller dyr. Denne metoden kan gi god informasjon om sammenhengen mellom kognitiv aktivitet og funksjonenes lokalisering i hjernen.
