Ultrashort and Short T2 signal detection in cartilage and meniscus: How low do we need to go?

This study examines the range of echo times (TEs) required to detect significant T2* differences in cartilage and meniscus between two clinically distinct cohorts: ACL-injured subjects without arthroscopic evidence of damage to medial femoral cartilage or medial meniscus, and uninjured controls. Reanalysis of MRI data from previously reported studies suggests that while UTE (TE<1ms) was not strictly required to detect differences between these two cohorts, inclusion of UTE (0.6ms) acquisitions augmented the ability of T2* calculation to discriminate between the cohorts, particularly in deep articular cartilage.
