Mr imaging of the knee at 3t – diagnostic performance and comparison with 1.5t

Abstract

The range of available magnetic field strengths for clinical knee MRI has expanded over the last 20 years, from below 0.2T to 1.5T, and, recently, 7T. The major advantage of high field strength MRI is the improvement in the signal-to-noise ratio (SNR), which can be used to either increase image resolution or decrease scan time and the chance for motion artifacts.
