Evaluation of 3.0-T MRI Brain Signal after Exposure to Gadoterate Meglumine in Women with High Breast Cancer Risk and Screening Breast MRI Neither the globus pallidus nor dentate nucleus display T1 signal increase after high cumulative doses of gadoterate meglumine (mean dose, 129 mL ± 57 [standard deviation]) in healthy women participating in a high-risk screening program for breast cancer. Analysis of both T1 time of dentate nucleus and the T1 dentate nucleus–to-pons signal ratio at unenhanced 3.0-T MRI showed no correlation with cumulative dose of gadoterate dimeglumine (P = .97 and .85, respectively). 50-year-old woman with 18 previous macrocyclic administrations of gadolinium-based contrast agent.
