ABSTRACT
The neuroradiology of today is multifaceted. On the clinical front it serves two important roles, namely diagnostic and therapeutic. This chapter reviews the clinical aspects of neuroradiology in two parts: diagnostic neuroradiology and interventional neuroradiology. CT-guided biopsy of vertebral and paravertebral lesions is part of a routine of any busy neuroradiology department. Practice of clinical neurology or neurosurgery without the help of magnetic resonance imaging (MRI) is virtually unimaginable today. MRI perfusion with or without contrast is used to characterize cerebral perfusion, as is done by CT perfusion. Diffusion tensor imaging (DTI) identifies various white matter tracts and understanding their relation to the cerebral or spinal lesion. The practice of interventional neuroradiology comprises diagnostic neuroangiography and neurointerventional procedures. Digital subtraction angiography (DSA) of the brain and spine, named neuroangiography, is the gold standard investigation for the diagnosis and evaluation of the most neurovascular disorders.
