Table I.

UTE bi-component analysis of 10 patellar samples (n = 10). Mean and 95% CI of the short and long T2*s and relative fractions are measured for subchondral bone, the deep radial and calcified layers, radial layer, middle layer, superficial layer and a global ROI involving all the layers. CPMG T2 analysis was also shown for comparison
