In this study, T₂* maps of degenerated meniscal specimens were obtained using MRI on an ultra-high field scanner in combination with an MR microscopy insert and these images were compared to histological findings. The results showed that all five investigated menisci specimens had very similar morphological appearance when comparing histological images, T₂* weighted images and T₂* maps.
