Fig. 5From: Comparison of standardized uptake values between 99mTc-HDP SPECT/CT and 18F-NaF PET/CT in bone metastases of breast and prostate cancerBland-Altman plots of a SUVRmax, b SUVRpeak, and c SUVRmean from SPECT and PET data for all lesions. The x-axis represents the mean of SPECT and PET SUVRs and the y-axis the difference between SPECT and PET SUVRs. Metastatic lesions are marked in red and benign in black. Solid lines with numerical values denote median differences and dotted lines with values denote 95% LOABack to article page
