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.
