## Abstract Preliminary results from __in vivo__ sodium MRI of human patellar articular cartilage are presented. Sodium images generated of an __in vitro__ bovine patella clearly distinguish the region of proteoglycan depletion from the region of healthy cartilage. This provides the first evidence

Abstract
The techniques and uses of MRI in current clinical practice, primarily as a means to detect morphologic abnormalities, are reviewed. Ongoing development of techniques that can improve morphologic assessment including techniques to increase spatial and contrast resolution is discussed, as are methods to measure cartilage volumes and thickness. Finally, several of the more widely studied techniques used to probe loss of the macromolecular structure of cartilage prior to the development of macroscopic defects are presented and compared. J.

## Abstract __T__~2~ and __T__~1Ο~ have potential to nondestructively detect cartilage degeneration. However, reports in the literature regarding their diagnostic interpretation are conflicting. In this study, __T__~2~ and __T__~1Ο~ were measured at 8.5 T in several systems: 1) Molecular suspension
The experiments reported herein are the first MRI investigations of the orientational dependence of T(2) relaxation in articular cartilage at microscopic resolution over the 360 degrees angular space. For each of six canine cartilage specimens, 48 independent T(2)-weighted proton images were acquire
