Overview
Quantitative MRI techniques such as T2 mapping T1rho and dGEMRIC provide objective measures of cartilage composition. High resolution isotropic sequences and 3D imaging improve preoperative planning. Ultrasound elastography complements MRI for tendon and soft tissue stiffness assessment.
Clinical Applications
Quantitative MRI aids early detection of degenerative changes and monitors response to biologic therapies. Advanced imaging supports sports medicine decisions and surgical planning for cartilage repair. Standardized acquisition and normative databases improve interpretation.
Technical Considerations
Quantitative sequences require careful calibration shimming and reproducible positioning to ensure comparability. Vendor differences and field strength effects necessitate harmonization for multicenter studies. Postprocessing pipelines should be validated and integrated into PACS for routine use.
Future Directions
Machine learning based segmentation and automated quantification will streamline workflows and enable large scale studies. Integration with biomechanical and clinical outcome data will refine prognostic models. Adoption depends on evidence of impact on management and patient outcomes.
