This book reviews in detail the role of neuroradiological imaging in the evaluation of patients who have undergone surgery or interventional radiology procedures, and particularly its value in the documentation of normal and pathological post-treatment changes, detection of complications, and follow- up. The opening sections describe pretreatment images in various conditions, including trauma, degenerative disc disease, and osteoporosis, and the different types of neurosurgical and interventional treatment that may be used. The post-treatment appearances of normal sequelae and complications on conventional radiography, CT, and MRI are then documented in detail on the basis of a large series of clinical cases, with a wealth of images.
