Title: Reducing radiation exposure in evaluation of ventricular shunt malfunctions in children<br/>Author: Jenny Guyther<br/><a href='http://umem.org/profiles/faculty/314/'>[Click to email author]</a><hr/><p>
Ventricular shunt (VP) malfunction can be severe and life-threatening and evaluation has typically included a dry CT brain and a shunt series which includes multiple x-rays of the skull, neck, chest and abdomen. The goal of this study was to decrease the amount of radiation used in the evaluation of these patients since these patients will likely present many times over their lifetime. Several institutions have more towards a rapid cranial MRI, however, this modality may not be readily available.</p>
<p>
This multidisciplinary team decreased the CT scan radiation dose from 250mA (the reference mA in the pediatric protocol at this institution) to 150 mA which allows for a balance between reducing radiation exposure and adequate visualization of the ventricular system. They also added single view chest and abdominal x-rays.</p>
<p>
The authors found that after implementing this new protocol, there was a reduction in CT radiation doses and number of x-rays ordered with no change in the return rate.</p>
