Typically, studies at our institution are now performed on a 3-T MRI scanner (Discovery MR, GE Healthcare) because the shorter scan time, compared with the 1.5-T scanners, translates into less motion degradation. WebPanel B uses a minimum intensity projection of an axial T2*-weighted MRI image (4 mm slab) to illustrate CMB (white arrows) in proximity to vessel flow voids on the brain surface. The vessels can be distinguished from CMB by their linear shape, while the CMB appear as blind-ended round or ovoid structures. sightseeing punta cana
