Although T2 mapping allows noninvasive evaluation of meniscus degeneration, its application at 7T requires spin echo sequences with relatively long repetition times to meet the specific absorption rate (SAR) limits which can restrict the resolution of maps. This 7T study evaluates the potential of T2* mapping for the assessment of meniscal degeneration in six patients with arthroscopically verified posterior root tears of the medial meniscus and in healthy volunteers. Increased T2* in degenerated meniscus regions suggest T2* mapping is sensitive to meniscus degeneration. T2* mapping is a promising biomarker of early meniscal degeneration which is less SAR-demanding than T2 mapping.
