Cerebral blood flow differences in cognitive disengagement syndrome and attention deficit hyperactivity disorder: Doppler ultrasonography findings.

Objective: The present study aims to investigate potential differences in cerebral blood flow between children with Cognitive Disengagement Syndrome (CDS) and those with Attention Deficit Hyperactivity Disorder (ADHD) using Doppler ultrasound.

Methods: In this single-center prospective study, we included 24 cases in the ADHD group with CDS symptoms, 29 cases in the ADHD group without CDS symptoms and, 26 children in the healthy controls. The children ranged in age from 6 to 15.

Visual assessment of cerebrospinal fluid flow dynamics using 3D T2-weighted SPACE sequence-based classification system.

Background: Flow-related signal void artifacts can be visualized on the T2-weighted (T2W) three-dimensional sampling perfection with application-optimized contrast (3D-SPACE) sequence. Flow void artifacts in the cerebral aqueduct and the fourth ventricle can provide information about cerebrospinal fluid (CSF) flow dynamics.

Purpose: In this study, we aimed to test the performance of the T2W 3D-SPACE sequence in assessing the CSF flow in the aqueduct and/or fourth ventricle.

Evaluation of the Relationship Between Radial Artery Intima Media Thickness and Complications at the Intervention Site After Radial Angiography.

The present study investigated the relationship between pre-procedural radial intima-media thickness (rIMT) and radial artery thrombosis (RAO) in patients undergoing angiography using a transradial approach (TRA). Patients (n = 90) who underwent cerebral or peripheral arterial angiography using TRA were included in the study. Ultrasonographic evaluation was performed before and 12 h after the procedure.
