Fig. 1D. True-positive sonographic findings and true-positive
scintimammographic findings in 49-year-old woman with palpable lump in right
breast. 99mTc-sestamibi scintimammograms show corresponding grade
II uptake (solid arrow, D) with bilateral axillary node uptake
(open arrows, D and E). Diagnosis was grade I
infiltrating duct carcinoma with negative nodes.

Fig. 2A. True-positive sonographic findings and false-negative
scintimammographic findings in 56-year-old woman with asymmetry on screening
mammography. Sonogram shows hypoechoic shadowing mass in 10-o'clock position
of right breast.

Fig. 2B. True-positive sonographic findings and false-negative
scintimammographic findings in 56-year-old woman with asymmetry on screening
mammography. 99mTc-sestamibi scintimammograms show no uptake in
area of lesion, but do show uptake in axillary nodes bilaterally
(arrows). Diagnosis was grade I infiltrating duct carcinoma with
negative nodes.
