Figure 5

(a) High-resolution coronal image (0.234 mm × 0.234 mm × 1.5 mm) of the left proximal femur in a 68 year old male obtained without parallel imaging (acceleration factor 1 (AF1)) and with parallel imaging at AF2, AF3, and AF4 using the novel 26-element coil setup. (b) High-resolution coronal image (0.234 mm × 0.234 mm × 1.5 mm) images of the left proximal femur obtained in a 65 year old male without parallel imaging (AF1) and with parallel imaging at AF2, AF3, and AF4 using the novel 26-element coil setup. (c) Mean image quality scores (5 = excellent, 4= good, 3 = average, 2 = poor, 1 = non-visualization) at each acceleration factor. Image quality was excellent at AF1, good at AF2, average at AF3, and at the level of non-visualization at AF4. There was no difference in image quality between AF1 and AF2 (p=0.18), but differences in image quality between AF2 and AF3 (p=0.02), and between AF3 and AF4 (p=0.001) were significant.
