Table 3 Reproducibility (coefficient of variation) [31] of T2 measurements in five subjects segmented three times each by one operator

From: Texture analysis of cartilage T2 maps: individuals with risk factors for OA have higher and more heterogeneous knee cartilage MR T2 compared to normal controls - data from the osteoarthritis initiative
