With the increased demand and utilization of PET/MRI in oncologic imaging, there is an ever increasing database of non-malignant pathology that has not yet been described on PET/MRI. Furthermore, the pediatric population provides an even more unique breadth of pathology that is often only seen in this age group. It is important to be able to accurately identify these common pathologies so as to not mistake them for malignancy and to prevent unnecessary follow up imaging studies and further invasive diagnostic procedures. For this educational exhibit we review over 200 clinical pediatric 18F-FDG PET/MRs performed at our institution and highlight the most common and most interesting cases of FDG-avid non-malignant pathology. <u>Listed below are some of the cases to be included in the poster</u>: -Benign FDG avid bone tumors including non-ossifying fibromas -Benign causes of FDG avid lymphadenopathy including cat scratch disease -Benign causes of FDG avid lung lesions including aspiration pneumonia -Benign causes of gastro-intestinal FDG uptake including pseudomembranous colitis -Benign FDG avid infectious pathologies including a liver abscess Read More

PET/MRI is a relatively new imaging modality whose efficacy is still being determined. One of the major draws to PET/MR over PET/CT is the reduction in radiation exposure to patients. This is especially desirable in the pediatric population due to the likelihood of multiple exposures during their lifetime, and the increased sensitivity they have to radiation. A typical whole body PET/CT exam can take about 30 minutes, whereas a typical whole body PET/MR exam takes about 90 minutes at our institution. The introduction of a new 3D T2 Dixon technique sequence for PET/MR has the potential of decreasing total scan time significantly, however maintaining current image quality and diagnostic value is critical. Our objective is to test out this new sequence to see whether scan times are reduced and if it is a viable diagnostic replacement for our current T2 sequence. Read More

In the diagnosis of acute appendicitis, unenhanced MRI provides an efficient and comprehensive evaluation of the appendix. However, on the daily clinical basis, there are cases that generate a diagnostic dilemma with subtle/indeterminate inflammatory changes. For these questionable cases, the morphology of the appendix could play a role as an aid for the radiologist to increase the confidence diagnosing or ruling out acute appendicitis. The aim of this study is to evaluate the morphology of the appendix as an additional tool for the diagnosis of appendicitis. Read More

Experience in pediatric nuclear medicine is limited and not uniform across residency and pediatric fellowship training programs. At our tertiary care pediatric hospital, emergent nuclear medicine exams performed after hours are currently read by radiologists with expertise in pediatric nuclear medicine. A decision to shift this responsibility to in-house faculty has prompted creation of a continuing medical education (CME) learning module as part of an institutional comprehensive learning management system (LMS). The goal of this module is to train faculty, fellows and residents in the indications, protocols, diagnostic criteria, potential pitfalls and problem-solving techniques when reading emergent pediatric nuclear medicine exams. The purpose of this study is to better understand the volume of nuclear medicine cases on-call and the potential need for a dedicated pediatric nuclear medicine curriculum. Read More

There is little data describing imaging sedation and anesthesia practice patterns in pediatric radiology. The purpose of this study was to understand current imaging sedation and anesthesia practice patterns based on a survey of member institutions of the Society of Chairs of Radiology at Children’s Hospitals (SCORCH) in conjunction with the American College of Radiology’s Pediatric Imaging Sedation and Anesthesia Committee.

The use of feed and swaddle (FS) technique in infants has increased in popularity due to the concern for neurotoxicity from medications used for anesthesia or sedation. The purpose for evaluating the age group &lt; 6 months of age was to understand current imaging sedation and anesthesia practice patterns based on a survey of member institutions of the Society of Chairs of Radiology at Children’s Hospitals (SCORCH) in conjunction with the American College of Radiology’s Pediatric Imaging Sedation and Anesthesia Committee.

Despite the global surge in adoption of Positron Emission Tomography Magnetic Resonance Imaging (PET/MRI) in healthcare, a formal educational framework for pediatric PET/MRI is lacking. The study aimed to conduct and report a needs assessment of pediatric radiology fellows, informing the development and implementation of a peer-reviewed pediatric PET/MRI curriculum and library.

Neuroblastoma is a clinically heterogeneous pediatric malignancy, varying in location, histopathologic appearance, and biologic characteristics. Genetics plays an important role in the prognosis. Amplification of the MYC family member, MYCN, is found in 25% of cases and correlates with high-risk disease and poor prognosis. However, genetic information can only be obtained via surgery or biopsy with concurrent morbidity and sampling variability associated with biopsy. The ability to detect MYCN amplification from routine pre-operative imaging can stratify neuroblastoma risk groups and affect clinical decision making. The purpose of this study was to predict the patient's MYCN status based on radiomics analysis of the magnetic resonance imaging (MRI) characteristics in patients with neuroblastoma. Read More

Nephron sparing surgery for renal masses is indicated for pediatric patients with bilateral renal masses and masses associated with syndromic conditions predisposed to recurrence. However, there is a paucity of literature on MRI-based biomarkers in patients undergoing partial nephrectomy. Relating these imaging biomarkers to patient outcomes might inform surgical decision making and patient counseling. Read More
