Evaluation of intraventricular lesions of the CNS by MRI: A pictorial review

While magnetic resonance imaging (MRI) findings on T1 weighted (T1W), T2 weighted (T2W), T2 fluid attenuated inversion recovery (FLAIR), diffusion-weighted imaging (DWI), gradient echo (GRE), and contrast enhancement play an important role in the diagnosis and characterization of intraventricular lesions, conventional MRI imaging still plays an important role in diagnosis with the advantage of reduced scan times and scope for increased daily cases. Advanced techniques, such as perfusion imaging, magnetic resonance spectroscopy (MRS), diffusion tensor imaging (DTI), and functional MRI (fMRI) have been added for further characterization on a routine basis in some centers. The objective of our pictorial review is to present typical conventional MRI findings for diagnosis and characterization of intraventricular lesions.
