We introduced and optimized a novel sequence of fast (about 4 min), volumetric, high resolution, simultaneous bright-and black-blood imaging with sufficient T 1 contrast between enhanced metastasis and surrounding brain parenchyma for their differentiation. This proposed sequence can be used for 3-dimensional volumetric T 1 -weighted bright-and black-blood imaging in contrast-enhanced studies and may be promising for detecting small brain metastases by improving differentiation between blood vessels and small brain metastases.
