Fig. 2From: Impact of contouring methods on pre-treatment and post-treatment dosimetry for the prediction of tumor control and survival in HCC patients treated with selective internal radiation therapyIllustration of two patients with MRI on the top (a and b) and tumors outlined in dark blue then registered on 99mTc-MAA SPECT/CT and 90Y-microspheres PET/CT via deformable registration. Yellow and light blue contours correspond to SPECT/CT and PET/CT 10% thresholds contours, respectively. First patient (a, c and e) had a very high TNR determined with MRI-based contours: 10 on SPECT/CT and 19 on PET/CT. Second patient (b, d and f) had a very low TNR: 4 on SPECT/CT and 3 on PET/CT. In those cases, for example first patient with a very high TNR had a tumor control during 38Â months and second patient with a very low TNR had a tumor control during 2Â monthsBack to article page
