Figure 1From: Imaging in situ breast carcinoma (with or without an invasive component) with technetium-99m pentavalent dimercaptosuccinic acid and technetium-99m 2-methoxy isobutyl isonitrile scintimammographyA 3-cm infiltrating ductal carcinoma of the right breast. Scintimammography, right lateral projection: 99mTc-(V)DMSA at 10 min and 60 min (upper row, i-ii); 99mTc-Sestamibi (99mTc-MIBI) at 13 min and 55 min (bottom row, iii-iv). Focal radiotracer accumulation (arrowhead) in the upper breast hemisphere, corresponding to the invasive tumor, visible in early and late images with both radiotracers. There is no diffuse uptake pattern in the breast; the studies are considered negative for in situ carcinoma.Back to article page
