Figure 4.

Accelerated single-shot (A-1S) magnitude images without and with SPIRiT reconstruction and fully sampled 4-shot (F-4S) images, both at 3mm isotropic resolution (nominal). Compared to the raw images (left), the aliasing artifacts of the SPIRiT-reconstructed images (A-1S) are significantly reduced. Compared to the 4-shot fully sampled counterparts (F-4S), the A-1S images show slightly more blurring because the single-shot spirals are longer (Table 1).
