Recently published data found that ultrashort echo-time MRI has the ability to better diagnose changes in cartilage deep tissue health, which could help delay or prevent the onset of osteoarthritis.
Researchers evaluated 31 patients with a mean age of 29.8 years who were undergoing anatomic ACL reconstruction (ACLR) and 11 healthy control patients. All patients underwent 3-T MRI while 16 patients in the ACLR group underwent the same MRI at 2 years postoperatively. Modified Outerbridge grades were given to the central medial femoral condyle (cMFC) and posterior medial femoral condyle (pMFC) for the ACL-reconstructed patients based on arthroscopic examination of the medial meniscus. Ultrashort echo time (UTE-T2) maps were constructed for the posterior medial meniscus (pMM), cMFC, pMFC and medial tibial plateau (MTP). Cross-sectional study of UTE-T2 and arthroscopic data and longitudinal analyses of UTE-T2 changes were also conducted.
