The goal of the research was to investigate T2 \u2013 relaxation parameters mapping as a possible marker for low-grade human articular cartilage lesions during a one-year follow-up, possible changes during the follow-up and compare the reliability and sensitivity of these measurements on high-field (3 T) and ultra-high-field (7 T) MRI scanners.<\/p>\n

The change in T2 values acquired with 3 T using method \u201cthree-dimensional triple-echo steady-state\u201d appears to be reflecting subtle changes of cartilage composition in the course of low-grade lesion development. 7 T T2 mapping does not reflect these changes probably due to completely decayed short T2 component.<\/p>\n

The new method will find application in clinical practice and as a source for further research.<\/p>\n
