Figure 3From: Alterations in anatomic and functional imaging parameters with repeated FDG PET-CT and MRI during radiotherapy for head and neck cancer: a pilot studyPercentage changes in anatomical and functional imaging parameters during radiotherapy. Plots of percentage change in GTV-CT, GTV-MRI, GTV-DW, GTV-PET, SUVmax, mean ADC value (ADC), Plasma Flow (PF), Plasma Volume (PV), Interstitial Volume (νe), Permeability Surface Area Product (PS), Extraction Fraction (EF) and Ktrans at baseline (B), fraction 11 (#11) and fraction 21 (#21) timepoints. ✶= median percentage change at each imaging timepoint. Coloured lines represent individual patients.Back to article page
