Nonsurgical management of patients with blunt hepatic injury: efficacy of transcatheter arterial embolization.
We evaluated the efficacy of transcatheter arterial embolization (TAE) for patients with blunt hepatic injury. ⋯ TAE is an effective alternative to surgery for patients with high-grade liver injury.

Blunt abdominal trauma in children: impact of CT on operative and nonoperative management.
The purpose of this study was to evaluate the impact of CT on operative management of children examined after blunt abdominal trauma. ⋯ CT rarely influenced the decision for operative intervention in children who sustained blunt abdominal trauma. CT findings affected the decision for operative intervention in most children with hollow viscus injury; however, CT findings affected such a decision in only a small subset of children with solid viscus injury. Normal abdominal CT findings strongly predicted a lack of subsequent deterioration requiring operative intervention.

Efficacy of ketamine hydrochloride sedation in children for interventional radiologic procedures.
The purpose of this study was to evaluate the efficacy of ketamine hydrochloride sedation in children younger than 11 years old who underwent short interventional radiologic procedures. ⋯ Ketamine hydrochloride provides excellent sedation and analgesia in young children. The short induction time, rapid recovery, and minimal respiratory depression are features that make this sedative ideal for interventional radiology.

Comparative StudyMR imaging of the gastrointestinal tract with i.v., gadolinium and diluted barium oral contrast media compared with unenhanced MR imaging and CT.
To determine an optimal MR imaging technique and pulse sequence for evaluating mural and serosal disease of the gastrointestinal tract, we administered 2% oral barium sulfate and obtained fat-suppressed gadolinium-enhanced breath-hold fast multiplanar spoiled gradient-recalled (FMPSPGR) MR images. We then compared these images with spin-echo T1-weighted and T2-weighted fast spin-echo MR images and with CT images. ⋯ MR evaluation of the gastrointestinal tract requires bowel distention with oral contrast material as well as motion reduction techniques, including glucagon and rapid gradient-echo pulses that allow breath-hold imaging. Fat-suppressed gadolinium-enhanced FMPSPGR MR imaging with diluted barium oral contrast media is effective for imaging benign and malignant mural and serosal abnormalities of the gastrointestinal tract.

Aspiration after administration of oral contrast material in children undergoing abdominal CT for trauma.
The practice of routinely administering oral contrast material to children undergoing abdominal CT for blunt trauma is controversial, primarily because of the increased risk of aspiration. The purpose of this study was to determine how often aspiration occurs in this population of children. ⋯ No clinically symptomatic episodes of aspiration pneumonia were found in 50 pediatric patients with blunt trauma who were given oral contrast material for abdominal CT. Although one of the children had CT findings that suggested clinically silent aspiration of oral contrast material, no evidence was found that administration of oral contrast material was harmful.
