  		FIG 1. MR images obtained in a 70-year-old man with metastatic brain tumor.

A, T1-weighted spin-echo image does not clearly show distinction between lesion (arrow) and surrounding edematous tissue.

B, T1-weighted FLAIR image clearly shows enhancing lesion (arrow).

  		FIG 2. MR images obtained in a 60-year-old man with multiple metastatic brain tumors.

A, T1-weighted spin-echo image has poor lesion-WM CNR (arrow).

B, T1-weighted FLAIR image clearly shows enhancing lesion (arrow).
