US findings will be presented alongside temporally-related MR enterography (MRE) images. CONTENT ORGANIZATION 1. We will identify pediatric small bowel Crohn disease patients that have undergone temporally-related bowel US and MRE examinations (within 0-14 days). 2. Bowel US technique will be presented. 3. Advantages/disadvantages of bowel US compared to MRE and CT will be reviewed. 4. Representative bowel US and correlative MRE images will be presented in a systematic, cased-based manner. The following will be illustrated: a. Bowel wall thickening, altered echogenicity, Doppler hyperemia, luminal narrowing/stricture, and dilatation (due to obstruction). b. Mesenteric abnormalities, such as fistulas/sinus tracts, fibrofatty proliferation, inflammation, and lymph node enlargement. c. Intra-abdominal fluid, including free fluid, phlegmon, and abscess. SUMMARY US excellently depicts bowel and mesenteric changes related to pediatric small bowel Crohn disease. This technique has numerous advantages, including low cost, lack of ionizing radiation, and no sedation requirement. Our exhibit demonstrates that bowel US is a viable imaging modality when assessing Crohn disease in children. Page 1 of 100 Neonatal Intensive Care: Necrotizing Enterocolitis-What Is the Best Way to Diagnose It? Back to Top CL-PDE3022 John R Mernagh , MD Yong Dong Wang , MD, PhD Nina P Singh , MD PURPOSE/AIM Necrotizing enterocolitis (NEC) is a serious condition in the neonate, believed to result from a combination of bowel infection and ischemia. The diagnosis however remains problematic with most diagnoses relying on plain film examinations and the identification of bowel wall thickening and pneumatosis intestinalis. The use of ultrasound and Doppler ultrasound in the diagnosis of necrotizing enterocolitis is a newer technique which has the potential of providing a more reliable diagnosis and method of following treatment. This presentation will review the use of ultrasound in the diagnosis of necrotizing enterocolitis. CONTENT ORGANIZATION In this pictorial review we will present the spectrum of ultrasound appearances of neonatal NEC. Included in the presentation will be: 1. A review of the diagnosis and assessment of severity of NEC with ultrasound with comparrison to plain film diagnosis. 2. A review of the use of Doppler ultrasound to assess bowel viability 3. A review of the best modalities for the assessment of NEC and specific protocols for the assessment of NEC SUMMARY Major teaching points: 1. Diagnosis and assessment of severity of NEC with ultrasound. 2. The use of Doppler ultrasound to assess bowel viability. 3. The best modalities for the assessment of NEC and specific protocols for the assessment of NEC. Fibroepithelial Polyps of the Urinary Tract in Children Back to Top CL-PDE3024 Mikhail Higgins , MD Kassa Darge , MD, PhD Tiffany Hwang * PURPOSE/AIM We present an educational pictorial essay outlining diagnostic considerations essential to increase the awareness of this understated entity in children and also aid the radiologist in timely and accurate preoperative characterization of this elusive diagnosis, allowing for appropriate directed management. CONTENT ORGANIZATION This exhibit will be structured to accomplish the following: Summarize the pediatric epidemiologic data regarding fibroepithelial polyps of the urinary tract in children. Present an overview of the radiographic features of fibroepithelial polyps in the core diagnostic modalities, namely ultrasound, excretory urography, retrograde pyeloureterography and MR urography. Discuss the critical problem of pelviureteric junction obstruction due to fibroepithelial polyps. SUMMARY Fibroepithelial polyps are rare benign primary ureteral neoplasms. Their presence in children presenting with flank pain, hematura, urinary tract infection and obstruction is often overlooked, resulting in missed diagnoses and improper clinical management, including ureteronephrectomy. Given the role of ureteroscopic laser ablation as a curative technique, we present the critical diagnostic considerations necessary to achieve early radiologic diagnosis, determine the need for histological sampling and ultimately guide definitive less invasive management. Imaging Inflammatory Bowel Disease in Young Patients: Which Modality to Choose and How Do Imaging Findings Impact Patient Management? Back to Top CL-PDE3025 Arash Anvari , MD Sudha A Anupindi , MD Michael S Gee , MD, PhD PURPOSE/AIM Review the role of imaging in the management of inflammatory bowel disease (IBD), discuss pros and cons of different modalities, and define an algorithm for imaging these young patients. CONTENT ORGANIZATION 1. Epidemiology and pathophysiology 2. Role of imaging in management
