<b>Background </b>Leg length discrepancy studies are labor intensive, yet cognitively simple, studies that represent inefficient use of the pediatric radiologists’ time and expertise. <b>Objective</b> The purpose of this study was to demonstrate that measuring and calculating leg length discrepancies do not require radiologist expertise. We hypothesized that radiology technologists could be trained to quantify leg length discrepancies and that their performance would be statistically equivalent to that of board-certified, fellowship trained pediatric radiologists.

ceVUS is a radiation-free and sensitive examination to detect vesicoureteral reflux and image the urethra in children using ultrasound (US) and intravesical administration of an ultrasound contrast agent (UCA). Due to the growing interest to perform ceVUS in children, a urinary bladder phantom was developed to teach the technical aspects of the ceVUS examination. Here we describe the preparation and utility of this reusable phantom as a tool to simulate the UCA administration, distribution and the effect of different US parameters on the UCA appearance in the bladder.

It is important for radiologists to recognize and discuss with patients and families the potential risks and clinical manifestations of high Peak Skin Dose. In children undergoing complex Interventional procedures accurate Peak Skin Dose estimates are complicated and time consuming despite reference point doses being available. The availability of the Dose Structure Report (SR) on modern fluoroscopic equipment allows such estimates to be timely and consistent. The process of creating a Peak Skin Dose estimate using a validated radiation data management system (RDMS), capable of collecting detailed acquisition data and modeling will be discussed. Read More

3D printing technology presents a unique opportunity for the creation of custom phantoms for training and simulation for pediatric interventional procedures that are complex and/or uncommonly performed. The purpose of this study was to describe the elements of designing a 3D phantom for simulation of pediatric abdominal intra -vascular procedures. Read More

The renal artery ostial anatomy, balloon profile, and stent deployment are all challenges of complex procedural RAS planning in children. In such cases there is an increased risk of renal artery rupture secondary to angioplasty requiring placement of a covered stent. This study aims to establish the feasibility of simulating renovascular stent deployment in three 3D printed pediatric patient-specific RAS endovascular phantoms. Read More

Intra-articular osteoid osteomas are uncommon and occur in only 10-13% of cases. Intra-articular osteoid osteomas may not demonstrate typical clinical features and feature subtle radiographic differences when compared to extra-articular osteoid osteomas. Radiofrequency ablation (RFA) has been found to be a safe and reliable method of treating osteoid osteomas. The possible complications of RFA include bleeding, muscle burn, and in cases of intra-articular osteoid osteoma, septhic arthritis. In this study, we evaluated the efficacy of radiofrequency ablation (RFA) of intra-articular osteoid osteomas at a single tertiary pediatric center. Read More

Percutaneous interventions are increasingly being performed under MR-guidance due to the absence of ionizing radiation, the ability to visualize target lesion and the capability to monitor real-time treatment effect. Here we outline our experience with developing an interventional MRI (iMRI) service at a pediatric institution. Read More

Low dose C-arm Computed Tomography (CT), is a technology that uses flat panel detectors to acquire real-time 3D images during an interventional radiology (IR) procedure to assist with anatomic localization and procedural mapping. This study describes our low dose protocol and applications of its use at a pediatric institution. Read More
