Abstract
Brain tumors may be primary (originating from brain itself), or secondary (metastatic from another primary site of cancer). The most common brain tumors are secondary metastasis while the primary brain tumors are the second commonest form of cancers in infants and children under the age of 15 years, after leukemia. Both primary and secondary brain tumors are capable of producing neurological impairment according to their location.Magnetic resonance (MR) imaging plays an important role in the detection and evaluation of brain tumors. a number of advanced MR imaging techniques have been developed that provide new methods for the assessment of brain tumors. One of these techniques is diffusion tensor imaging (DTI).The aim of this work in this study was to demonstrate the role of DT imaging in preoperative mapping of white matter tracts in relation to cerebral neoplasms and the way it can influence the operative decision in our practice in order to achieve a maximal resection of the tumor without causing neurological deterioration.This study was conducted on 34 patients with respectable brain tumours, the cases collected starting from January 2016 to July 2018. The study was approved by the Research Ethical Committee, Faculty of Medicine, Tanta University.
