    Structured Review

    MathWorks Inc nonlinear regression using a double gaussian model
    ADC histogram analysis and targeted biopsy acquisition. Pre and post contrast T1 MR images were acquired ( A ) to evaluate ADC levels of each voxel of enhancing tumor ( B ) to yield an ADC histogram ( C ). A double <t>gaussian</t> model (black line) was applied to this histogram (light blue line) to identify the higher (ADC H , red line) and lower (ADC L , blue line) distributions. A probability map ( D ), representing probability of a voxel occurring in the ADC L distribution was used to prospectively identify biopsy targets ( E ). These targets were loaded onto T1 with contrast images on intraoperative neuronavigation software ( F ) to facilitate tissue collection during tumor resection ( G ).
