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

Figure 5

Slice through a representative subject’s breast, with the skin removed (left). Segmented images (right) from the same breast using (a) minimum, (b) cross-point, and (c) 95% interval methods described in the text. All images are equivalently windowed and leveled. The minor differences in the resultant images due to the segmentation methods may indicate a lack of need for procedures more sophisticated than a simple threshold.
