Trabecular bone characterization with low-field MRI.
Multiple-echo (ME) T2 measurements were performed in vitro at 0.1 T on a series of human trabecular bone samples filled with water and compared to site-matched bone density measurements. Multiple-echo T2 is strongly correlated to bone density and allows distinction between samples of equivalent bone density. Multiple-echo T2 is also dependent on the trabecular orientation with respect to the direction of the main field.
