3T MRI up-to-date demonstrating brain structures

Abstract

This paper is to introduce how state-of-the-art 3T MRI demonstrates fine brain structures. The 3T MRI has an advantage over the 1.5T MRI in demonstrating smaller structures much more clearly. An important factor of this advantage is the high magnetic field strength that results in higher signal to noise ratio, increased magnetic susceptibility effect and elongation of T1 relaxation time.
