Table 1.

Intra-reader reproducibility errors for cartilage T2 measurements were calculated for each compartment and layer as the root mean square error (ms) and as the root mean square error coefficient of variation (%). LF: lateral femur, LT: lateral tibia, MF: medial femur, MT: medial tibia, and PAT: patella. The reproducibility errors averaged over all five compartments are printed in bold.

	whole compartment [%]	whole compartment[ms]	deep layer [%]	deep layer [ms]	superficial layer [%]	superficial layer [ms]
LF	1.52	0.53	2.13	0.72	2.05	0.75
LT	0.90	0.28	2.08	0.61	1.57	0.55
MF	0.90	0.35	1.48	0.56	1.52	0.60
MT	2.61	0.88	2.40	0.81	4.46	1.67
PAT	2.38	0.71	4.92	1.38	1.63	0.55
mean	1.66	0.55	2.60	0.82	2.24	0.82
