MRI of osteoporosis-related anatomical locations are generally acquired with a surface coil in order to obtain sufficient sensitivity and resolution for quantification of the trabeculae, however these coils introduces intensity inhomogeneities which affect the analysis of the trabecular bone structure. This work demonstrates the benefits of intensity normalization based coil correction for MRI data acquired with phased array coils in trabecular bone structure analysis compared to low-pass filtering.
