FIGURE 1. A 39-y-old patient with extensive palpable and dense left breast mass reported as equivocal on conventional two-view XMM (A and B) and reported as cancer on 99mTc-MIBI SMM (C). Invasive ductal carcinoma, BloomRichardson grade 2 (20), was confirmed on histologic examination.
FIGURE 2. A 30-y-old patient with palpable lesion reported as probably cancer (grade 4) on two-view XMM (A and B) but reported as normal on 99mTc-MIBI SMM (C). Histologic examination confirmed benign fibrocystic changes only.
FIGURE 3. A 52-y-old patient with palpable lesion and right breast mass reported as normal (A and B); likewise, 99mTc-MIBI SMM (C) was reported as normal. Pathologic examination of excision biopsy specimen showed 20-mm grade 2 invasive ductal carcinoma.
