Fig. 1From: Accuracy and precision assessment for activity quantification in individualized dosimetry of 177Lu-DOTATATE therapy 177Lu energy spectrum acquired on SPECT/CT camera. Four energy windows were defined but only the 208 keV photopeak window A (20% width [187.56–229.24 keV]) and the lower scatter window B (10% width [166.72–187.56 keV]) were usedBack to article page
