A 61-year-old man with brain metastases from primary lung cancer. A 61-year-old man with brain metastases from primary lung cancer. Images were acquired before (A, unenhanced T1 SE) and after (B, T1 SE; C, high-resolution T1 GRE) administration of gadoteridol and before (D, unenhanced T1 SE) and after (E, T1 SE; F, high-resolution T1 GRE) administration of gadobutrol. Two lesions clearly seen in both examinations show no differences in contrast enhancement or in the size of lesions. K.R. Maravilla et al.
