Fig 1. Melanoma brain metastases were detected principally on T2*-weighted sequences in 7% of 120 lesions. T1 isointense, nonenhancing lesions are seen in the right cerebellar hemisphere lesion (top row) and left frontal lobe (bottom row). A subtle abnormality can be seen on the FLAIR image (G), but the lesion is markedly more conspicuous on T2*-weighted image (H). T1-weighted sequences before (A, E) and after (B, F) administration of gadolinium, FLAIR sequences (C, G), and T2*-weighted sequences (D, H) are shown.
