Initial In Vivo Quantification of Tc-99m Sestamibi Uptake as a Function of Tissue Type in Healthy Breasts Using Dedicated Breast SPECT-CT

(a) The graph illustrates a representative subject’s breast volume histogram and corresponding dual-Gaussian fit. The value indicates a high quality fit, allowing for various segmentation methods based on the minimum, cross-point, and percentage contribution to be compared. (b) Two normalized representative single-slice histograms from the same subject, along with estimated breast size. The graph clearly demonstrates the shift in attenuation coefficients as a function of object radius.
