Figures
- FIGURE 1.
Upper and lower left MLO images from subject in group 1 after initial injection (A and B) of 99mTc-sestamibi and immediately before (C and D) and after (E and F) second injection of 99mTc-sestamibi. Identical ROI was copied onto all images for measurement of count density.
- FIGURE 2.
Relationship between measured biologic washout factor of 99mTc-sestamibi and interval between imaging of subjects in groups 1 and 3.
- FIGURE 3.
Relationship between count density in all participating subjects, assessed in fasting state, and body surface area.
- FIGURE 4.
Relationship between count density, assessed in fasting state in all participating subjects, and breast density assessed from most recent mammogram.
- FIGURE 5.
Correlation between count density in breast from subjects in group 1 in fasting and fed states. Dotted line = line of identity.
- FIGURE 6.
(A) Average percentage increase in breast count density between fasting and fed states for subjects in group 1. (B) Average percentage increase in breast count density between subjects before and after peripheral warming (group 3).
- FIGURE 7.
Summary of count density in breast for subjects in each of the 4 study groups and those in reference group.
