T1-CUBE is a technique for fast spin-echo based MRI with variable flip angle. This study is to compare the enhancement of brain tumors between T1-CUBE and 3DFSPGR at 3T MRI. We measured the contrast ratio which is the signal intensity (SI) of a tumor and normalized by SI of the white matter for each sequences. The contrast enhancement of tumors by T1-CUBE is higher than by 3DFSPGR, especially in the small tumors, the enhancement by T1-CUBE is prominent than that in the large tumors.T1-CUBE is considered to be useful to pick up the small tumor lesions screening for brain metastasis.
