Figure 3.

Representative frames of MRI movies of (A,B) spoiled and (C,D) refocused radial FLASH acquisitions of a midsagittal section through the head during speaking. (A,C) Reconstructions using all coils and (B,D) of a subset of coils after sinogram-based selection. Images using all coils show prominent streak artifacts (arrows) originating from the fat in the neck, whereas sinogram-based coil selection reduces the intensity of these artifacts greatly. MRI, magnetic resonance imaging; FLASH, fast low-angle shot.
