Diffusion-weighted MR Imaging of Bone Marrow in the Spine: Differentiations of Metastatic Compression Fracture,Benign Compression Fracture,

Study of Apparent Diffusion Coefficient Changes According to Spinal Disease in MR Diffusion-weighted Image

“…Generally, a b value of about 400 s/mm 2 can be imaged during spinal examination to image the signal loss due to diffusion. Rho [14] et al measured the signal intensity in diffusion-weighted images by using b value of 150 s/mm 2 in patients with vertebral fractures classified into four categories such as acute osteoporosis, metastasis, chronic osteoporosis and spondylitis. On MRI, metastatic compression fractures and spondylitis have high signal intensity, acute osteoporotic compression fractures have low signal intensity, and chronic osteoporotic compression fractures show various signal intensities.…”
