1. A method of analyzing trabecular bone structure of a patient comprising the steps of:
- selecting an anatomical region comprising the trabecular bone for scanning;
selecting a magnetic resonance imaging coil for scanning the selected region;
positioning and immobilizing the selected region relative to the coil, thereby minimizing movement;
thenscanning trabecular bone of the patient using a magnetic resonance image (MRI) scanner to generate bone image data, wherein image data comprises data acquired by signals emitted from bone marrow regions of the scanned trabecular bone;
processing the image data comprising correcting the image data to compensate for involuntary movement by the patient during scanning;
deshading the image data to minimize the effects of radio frequency inhomogeneity and reducing noise in the image data; and
outputting the processed image data or derived quantitative parameters, or combinations thereof.

Abstract
The present indention comprises a system and method for analyzing trabecular bone structure. A means for scanning the trabecular bone using a magnetic resonance image (MRI) scanner generates bone image data, which is then processed including correcting, deshadi4 and reducing noise in the image data.
