Fig. 2. —Bar chart shows contrast-to-noise ratio (CNR) with (b = i) without (b = 0) and diffusion-sensitizing gradients in benign fracture edema and malignant lesions with and without accompanying fracture. In benign fracture edema, statistically significant difference between sequences without (b = 0) and with (b = i) diffusion-sensitizing gradients was found (p < 0.05), whereas malignant lesions independent of accompanying fractures lacked statistical significance. Only in diffusion-weighted images was CNR between two entities of vertebral fracture (benign and malignant) significantly different (p < 0.05). (b(i) = 598 sec/mm² in spin-echo sequences (white bars) and fat-suppressed spin-echo sequences (black bars) and 360 sec/mm² in stimulated-echo (gray bars) sequences.
