Advances of 3T MR imaging in visualizing trabecular bone structure of the calcaneus are partially SNR-independent: Analysis using simulated noise in relation to micro-CT, 1.5T MRI, and biomechanical strength

Purpose To investigate differences in magnetic resonance imaging (MRI) of trabecular bone at 1.5T and 3.0T and to specifically study noise effects on the visualization and quantification of trabecular architecture using conventional histomorphometric and nonlinear measures of bone structure.
