Advanced MR techniques in brain tumor imaging and the application at Choray hospital
Main Article Content
Abstract
MRI is the imaging modality of choice for brain tumours. Advanced MRI techniques have significantly developed
and used clinically in imaging of brain tumor such as: diffusion-weighted imaging (DWI), perfusion-weighted imaging
(PWI), diffusion-tensor imaging (DTI) and magnetic resonance spectroscopy (MRS). Conventional MR imaging
(MRI) provides mainly anatomic or structural information about the brain and tumor. Unlike conventional imaging,
advanced MR techniques also provide physiological information concerning tumor cellularity, white matter invasion,
metabolism and hemodynamics.These techniques can be used to diagnosis, differential diagnosis, grading, surgical
planning, and monitoring of therapeutic response of brain tumors.
A principles of the physiology, techniques, and clinical applications of these techniques is provived. Some
experience of using these technique in the domain of brain tumor at Choray Hospital were also presented in this
article.
