Multiparametric MRI Evaluation of Developmental Venous Anomalies in the Brain: Association with Signal Changes on FLAIR in Patients with Multiple Sclerosis.

Background: Developmental venous anomalies (DVAs) can be determined on magnetic resonance imaging (MRI), and they may be associated with multiple sclerosis (MS) lesions.

Purpose: The objective was to evaluate the MRI findings of DVAs in the brain, to compare the prevalence of them between MS patients and control subjects, and to investigate the correlation of DVA-associated fluid-attenuated inversion recovery (FLAIR) hyperintensities and MRI-derived parameters between MS patients and control subjects having DVA.

Methods: Total 160 patients with a mean age of 45 ± 16 years who underwent multiparametric MRI including susceptibility-weighted imaging (SWI), diffusion-weighted imaging, 3D FLAIR, and contrast-enhanced imaging were included in this retrospective study.

The disrupted connection between cerebral hemispheres in schizophrenia patients: a diffusion tensor imaging study.

Aim: In schizophrenia, the disruption of the communication between two brain hemispheres has not been shown clearly in the anatomical aspect despite other studies with different modalities suggested so. In this study, the structural integrity and the variables affecting the structural integrity of the corpus callosum, which is the main connection between two hemispheres, was investigated via diffusion tensor imaging (DTI).

Methods: The participants were evaluated by SCID-I and symptoms of the patients were assessed with PANSS.
