Correlation between optic nerve sheath diameter and Rotterdam computer tomography scoring in pediatric brain injury.

Background: Pediatric head trauma is the most common presentation to emergency departments. Increased intracranial pressure (ICP) may lead to secondary brain damage in head trauma and early diagnosis of increased ICP is very important. Measurement of optic nerve sheath diameter (ONSD) is a method that can be used for determining increased ICP.

Acoustic radiation force impulse (ARFI) elastography in the evaluation of renal parenchymal stiffness in patients with ureteropelvic junction obstruction.

Purpose: To investigate the role of acoustic radiation force impulse (ARFI) elastography in the detection of renal parenchymal damage in kidneys with and without ureteropelvic junction obstruction (UPJO).

Methods: Twenty-five pediatric patients with a diagnosis of UPJO who underwent surgery and 15 pediatric patients with conservatively managed UPJO were prospectively evaluated with ARFI elastography. Sixteen healthy volunteers constituted the control group.
