Sumary of New QIBA profile for knee cartilage MRI:
- New recommendations will help provide more reliable, reproducible results for MRI-based measurements of cartilage degeneration in the knee, helping to slow down disease and prevent progression to irreversible osteoarthritis, according to a special report published in the journal Radiology.
- “By the time there is structural damage to the cartilage, treatment choices are very limited,” said paper coauthor Majid Chalian, M.
- , assistant professor of radiology and section head of musculoskeletal imaging and intervention in the Department of Radiology at the University of Washington in Seattle.
- “We cannot treat the damaged cartilage, and we cannot prevent osteoarthritis because the cartilage is not going to regrow.
- ” MRI-based cartilage compositional analysis is a promising tool for revealing biochemical and microstructural changes in the early stages of osteoarthritis.
- Two advanced MRI techniques, T1rho and T2 mapping, have been established for assessing cartilage composition.
- “The issue with these compositional cartilage imaging measurements is that the reliability and reproducibility of the numbers are not great,” Dr. Chalian said.
- ” To address these shortcomings, Dr. Chalian and his colleagues from the Radiological Society of North America’s (RSNA) Musculoskeletal Biomarkers Committee of the Quantitative Imaging Biomarkers Alliance (QIBA) collaborated to create a QIBA profile for cartilage compositional imaging.
