Gambaran Radiologis pada Bidang Neurologis Tumor Otak

Abstract

Along with increasing life expectancy and advances in medical technology, the incidence of brain tumors continues to increase. Brain tumors can cause changes in mental status, neurological deficits, and create a large social burden. The incidence of benign brain tumors is 71% and these benign brain tumors develop twice as often in women as in men. Diagnosis brain tumors requires radiological examinations that can quickly diagnose brain tumors and must be done immediately. Source searches were carried out on the online portal of journal publications as many as 20 sources from MedScape, Google Scholar and the Nation Center for Biotechnology Information / NCBI with the keywords "brain tumor" and "radiology of brain tumor". Brain tumors cause progressive neurological disorders. Neurologic disorders in brain tumors are usually caused by two factors, namely focal disturbances due to tumors and increased intracranial pressure. The most commonly used radiological techniques are T1/T2-Weighted MRI, MR Spectroscopy, Diffusion MRI, Perfusion MRI, and Brain Tumor CT Scan. MRI is a powerful and flexible instrument for evaluating patients with primary brain tumors. Integration of the RANO criteria into treatment evaluation helps reduce premature discontinuation of effective therapy due to treatment-related imaging changes.
