A method for the assessment of articular cartilage thickness based on MRI is presented and tts accuracy and reproducibil‐tty tested. Six specimens of human patellae were imaged, using a fat‐supressed FLASH 3D sequence, and sectioned with a high‐precision band saw. The reglonal dlstribution of articular cartilage thickness was determined from the MR images and from the anatomical sections (intervals of 0.5 mm). Wtth image analysis 50–90% of the image points were found to lie within exactly the same thickness interval in corresponding patterns, and tess than 17% deviated more than 0.5 mm. More than 85% of ali pixels were reproducible wtth MRI after new positioning of the Joint No influence of the read‐out direction and no important differences between areas of thin and thick cartilage could be detected. The authors conclude that MR chondro‐crassometry can provide accurate and reproducible Information on cartilage thickness.
