Objective: The Image Gently, Step Lightly campaign is an education and awareness campaign focusing on radiation safety in pediatric interventional radiology. To promote radiation safety by standardizing workflow and encouraging team responsibility, the campaign Website includes a procedural checklist that the medical team may use to review radiation safety steps before each pediatric interventional procedure., Conclusion: Use of this checklist can be an effective tool in the ongoing effort to maximize radiation safety during interventional procedures.

Objective: The purpose of this study was to determine whether there are clinical or sonographic findings that can be used to differentiate benign self-limited small-bowel intussusception from pathologic small-bowel intussusception that necessitates surgical intervention., Materials and Methods: A retrospective search was performed of abdominal sonograms obtained at two institutions between January 1996 and June 2005. Sonographic findings were correlated with medical and surgical records., Results: A total of 35 cases of isolated small-bowel intussusception were found. Thirteen (37%) of these cases necessitated surgical intervention, and 22 (63%) of the cases were benign and self-limiting. Patients with self-limiting intussusception were younger than patients with intussusception necessitating surgical intervention (mean, 4.2 vs 7.5 years; p = 0.0327). Abdominal sonograms depicted ascites and small-bowel obstruction significantly more frequently in patients with small-bowel intussusception necessitating surgery (n = 7 [54%] for each finding) than in patients with self-limiting intussusception (n = 2 [9%], n = 0) (p = 0.006 and p = 0.0003, respectively). At sonography, patients who later underwent surgical intervention had small-bowel intussusception of significantly greater length (mean, 7.3 cm) than those treated conservatively (mean length, 1.9 cm) (p < 0.0001). Intussusception length greater than 3.5 cm was considered a sensitive and specific independent predictor of the need for surgery (sensitivity, 93%; specificity, 100%)., Conclusion: When small-bowel intussusception is detected in infants and children undergoing abdominal sonography, intussusception length greater than 3.5 cm is a strong independent predictor of the need for surgical intervention.

Objective: Cerebrospinal fluid (CSF) pseudocyst formation is an uncommon cause of ventriculoperitoneal shunt malfunction in children. Traditional staged treatment consists of shunt externalization, antibiotics, and later shunt revision and internalization. We sought to evaluate whether sonographically guided pseudocyst aspiration to alleviate acute symptoms and to exclude CSF infection could obviate shunt externalization and expedite the care of these patients., Conclusion: Sonographically guided CSF pseudocyst aspiration is an effective technique, allowing exclusion or confirmation of infection and providing relief of abdominal symptoms. In patients with sterile collections, staged surgical revision with shunt externalization can be avoided, speeding and simplifying treatment.
