Delayed phase imaging increases the sensitivity of detection of injuries to the urinary tract and also assists in characterizing solid visceral organ injuries at the expense of doubling the radiation dose to the patient. If institutions can lower the rate of these examinations, the cumulative radiation exposure reduction would be substantial. Here we evaluate the rate of delayed phase imaging in the pediatric trauma population at our Level I trauma center as well as the frequency with which these patients demonstrate an indication on portal venous imaging for delayed phase acquisition. Finally, there are minimal guidelines dictating the appropriateness of delayed imaging in pediatric trauma. We include a review of the literature in order to elucidate appropriate indications and help guide clinicians to make evidenced based decisions. Read More

Our educational poster will evaluate and present the complications of the Medtronic Intrathecal Baclofen Pump as seen by our institution. Intrathecal Baclofen pumps are indicated as the treatment for intractable spasticity secondary to cerebral palsy and spinal cord injuries. However, it is not without complications and thus, reserved only for those refractory to other medical interventions. After reviewing radiographs available at our institution, we seek to discuss the complications of baclofen pumps using a multi-case illustration. We present some interesting radiographs of complications seen during infusion pump aspiration studies. These complications include the inability to aspirate CSF, catheter disconnection, catheter fracture, and malposition of catheter tip. Other complications of baclofen pumps include CSF leakage, infections, and even death. It is important to understand these complications because rapid intervention decreases morbidity and mortality rates. Read More
