Fig. 3B —47-year-old woman with two histologically confirmed invasive
lobular carcinoma lesions in left breast. Suspicious contrast-enhancing lesion
(arrow) with correspondingly suspicious signal intensity–time
curve is clearly visible on subtracted T1-weighted gradientecho images after
administration of 0.1 mmol/kg of gadopentetate dimeglumine (A) and of
0.1 mmol/kg of gadobenate dimeglumine (B). Both degree of enhancement
and lesion conspicuity are greater after gadobenate dimeglumine. Signal
intensity–time curves for gadopentetate dimeglumine (A) and
gadobenate dimeglumine (B) show similar washout behavior, which is
characteristic for malignant lesion.
