The advanced statistics in region-of-interest based cartilage MRI is introduced. Correction parameters were determined as the fitting errors estimates (R2, RMSE, MSE, MAE) from non-linear least square fitting calculation of T2. Functionality of improved statistics was tested on noise-simulated images. Using the error estimates as a weighting parameters in the ROI evaluation in musculoskeletal MRI may crucially improve the differentiation of native and transplant cartilage tissue even in images suffering of low SNR. This has a great potential to improve the non-invasive monitoring of the post-operative status of patients with cartilage transplants using MR systems with lower B0.
