Purpose: To compare diffusion-weighted echo-planar imaging (DW) with spin-echo (SE), and fluid-attenuated inversion recovery (FLAIR) sequences in the evaluation of epidermoid cysts (ECs), and to evaluate T2 shine-through effect.
Materials And Methods: Fifteen patients were imaged prospectively in two different 1.5 T magnetic resonance (MR) units with standard head coils with SE, FLAIR and DW echo planar imaging sequences.
Purpose: The differential diagnosis between brain abscesses and necrotic tumors such as glioblastomas and metastases is often difficult by conventional MRI. The goal of our study was to evaluate the ability of the diffusion-weighted (DW) MRI to differentiate these lesions from each other.
Materials And Methods: MRI was performed in 19 patients (four abscesses, seven glioblastomas, two anaplastic astrocytomas, six metastases).
Purpose: To explore the use of fluid-attenuated inversion recovery (FLAIR) and diffusion-weighted echo planar imaging sequences in imaging of the intracranial epidermoid and arachnoid cysts and assess the efficiency of those sequences in differentiation of epidermoid cysts from arachnoid cysts.
Materials And Methods: This study was performed prospectively by using two different MR devices in 24 patients (12 epidermoid cysts, 12 arachnoid cysts). T1-weighted spin echo, T2-weighted fast spin echo, FLAIR and diffusion-weighted echo planar imaging sequences were used.
