Two-thirds of degenerative diseases of the vertebral column involve the lumbar spine. Magnetic resonance imaging plays a pivotal role in diagnosis and treatment. With more than 450 illustrations and 78 case studies illustrating various constellations of findings, this book provides a wealth of illustrations that guide the reader through the MR imaging of lumbar disk herniations and spinal stenosis: Impressive series of MR images illustrate both common and unusual findings, helping to enhance conceptual understanding and sharpen diagnostic perception. Clinical findings and progression are covered in addition to MRI findings, helping the reader to appreciate the correlations between clinical and imaging findings. The role of diagnostic imaging is addressed for specific disorders, helping to foster the more discriminating use of imaging procedures in the lumbar spine. The book concludes with a chapter on the current technique of performing CT-guided injections at the lumbar level.
