2 Visualizing joint structures with MRI. MRI has the capability of obtaining exquisite images of the morphology of the tissues of the joint. Deborah Burstein, and Martha Gray J Bone Joint Surg Am 2003;85:70-77 ©2003 by The Journal of Bone and Joint Surgery, Inc.

3 Morphometric analysis of joint MR images. a, The difference in the MRI parameters among the different tissue structures allows them to be distinguished from one another and segmented for tissue-specific analysis.

4 Extracellular matrix architecture as visualized with T2-weighted MR images. a, A high-resolution T2-weighted image (in-plane resolution, 80 mm) shows striations within the cartilage that correspond with the collagen architecture in microscopy studies.

5 Extracellular matrix molecular composition and structure as visualized with T2-weighted imaging. Deborah Burstein, and Martha Gray J Bone Joint Surg Am 2003;85:70-77 ©2003 by The Journal of Bone and Joint Surgery, Inc.

6 Glycosaminoglycan composition as visualized with dGEMRIC imaging. Deborah Burstein, and Martha Gray J Bone Joint Surg Am 2003;85:70-77 ©2003 by The Journal of Bone and Joint Surgery, Inc.

7 Comparison of radiographic versus dGEMRIC measures of disease. a, In a study of forty-three patients with hip dysplasia, the standard radiographic measure of joint-space narrowing did not differentiate among groups of patients with different degrees of seve...
