FIG 5. Transverse images from one section of the brain of a 74-year-old patient with occlusion of the middle cerebral artery, 10 days after onset of stroke symptoms.
A, Standard T1-weighted fast spin-echo image (400/15/2 [TR/TE/excitations]).
B, Standard T2-weighted fast spin-echo image (4000/117/1).
C, Single-scan half-Fourier image. Section thickness, 12 mm; FOV, 250 x 500 mm; matrix, 96 x 256; TE = 155; no diffusion sensitivity.
D, Single-scan half-Fourier image. Section thickness, 12 mm; FOV, 250 x 500 mm; matrix, 96 x 256; TE = 155; diffusion preparation with a b value of 1000 s/mm2. CNR of the lesion (arrows) versus normal brain is 12.
E, Ten single-scan images from a set of 20 images were averaged. Half-Fourier approach, section thickness, 10 mm; FOV, 175 x 350 mm; matrix, 96 x 256; TE = 155; no diffusion sensitivity.
F, Ten single-scan images from a set of 20 images were averaged. Half-Fourier approach, section thickness, 12 mm; FOV, 250 x 500 mm; matrix, 96 x 256; TE = 155; diffusion preparation with a b value of 1000 s/mm2. CNR of the lesion versus normal brain is 13.
