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.
