Patient demographic and histologic data is reported. Mean and range of each DWI parameter is given for each reconstruction method. P–value corresponds to significance of paired Student’s t-test between parameters from CMA versus BLN reconstructions.
CMA = conventional magnitude averaging reconstruction. BLN=beta*log normal reconstruction.
