Images obtained in a 57-year-old-man with small-cell lung cancer reveal multiple, enhancing, solid and cystic parenchymal metastases. The number, conspicuity, and contrast enhancement are superior on the postcontrast FLAIR image compared with the postcontrast T1W image. In this patient, FLAIR was performed as the second postcontrast sequence.A, Contrast-enhanced T1W image.B, Nonenhanced FLAIR image.C, Contrast-enhanced FLAIR image. Nil Ercan et al.
