Of mr imaging in the workup of intraaxial tumors can be broadly divided into tumor diagnosis and classification treatment planning and posttreat ment surveillance in addition to conventional mr imaging tech niques a variety of advanced techniques have found their place in clinical practice or are the subject of intense research these . This article presents a summary of advanced mr imaging techniques and their use in the evaluation of patients with brain tumors it reviews diffusion weighted imaging diffusion tensor imaging t2 susceptibility sensitive imaging mr spectroscopy mr perfusion and functional mr imaging and discusses their current roles in the evaluation of patients with brain tumors. Intracranial masses are a significant health problem and present several imaging challenges the role of imaging is no longer limited to merely providing anatomic details but the advanced mr techniques permit the assessment of the freedom of water molecule movement the microvascular structure and hemodynamic characteristics and the chemical makeup of certain metabolites of lesions. The last decade has seen an increase in the development and application of various functional imaging techniques such as mr spectroscopy diffusion and perfusion weighted mri perfusion ct optical imaging and nuclear medicine based tools these functional imaging techniques address conditions. In this article we illustrate the main advanced magnetic resonance imaging mri techniques used for imaging of the spine and spinal cord in children and adults this work focuses on daily clinical practice and aims to address the most common questions and needs of radiologists we will also provide tips to solve common problems with which we were confronted
