1. A 77-year-old man with a left occipital anaplastic astrocytoma.
A 77-year-old man with a left occipital anaplastic astrocytoma. Images acquired before (unenhanced T1SE, A) and after (T1SE, B; T1GRE, C) administration of 0.05-mmol/kg gadobenate. Images acquired before (unenhanced T1SE, D) and after (T1SE, E; T1GRE, F) administration of 0.1-mmol/kg gadoterate. A single irregular ring-enhancing mass is clearly seen in both examinations; similar appearances and lesion definition and size are seen in both. All blinded readers gave similar scores for global preference, border delineation, internal morphology, and contrast enhancement, indicating equivalence for 0.05-mmol/kg gadobenate versus 0.1-mmol/kg gadoterate.
