The purpose of this study is to outline the benefit of speed stitching and recognize it as one of the best stitching tools available for the pediatric population. Looking at the history of stitching, we started by using the CR for scoliosis and long bones stitching. The time of exposure, the radiation dose, and image quality were not optimal. Moving to automatic DR stitching was a good step in the right direction. However, there was still a frustration from having to repeat so many exams because of the high possibility of motion captured between exporsures. That’s when speed stich came to play with fast acquisation and less operator interference while doing the exam. Read More

During a recent CT renovation, a mobile CT scanner had to be used at a major urban children's hospital which also is a Level 1 trauma center. Performing exams while maintaining patient safety and providing quality diagnostic imaging involved the collaborative efforts of the radiology team, the project manager, the construction team, and the hospital service line leaders. The purpose of this exhibit is highlight the anticipated and unanticipated considerations which had to be addressed prior to the use of the mobile CT scanner. Knowing how these environmental and patient safety issues were identified and addressed may be a help with future radiology equipment replacement projects. Read More

To describe the radiographic appearance of subclinical calcified brown fat necrosis and to delineate the associated clinical and laboratory findings. While brown fat necrosis has been described in infants with underlying cardiac disease treated with prostaglandins, we emphasize hypotension from cardiac or respiratory arrest as a primary risk factor.

To describe and discuss some of the challenges of performing DEXA scans on pediatric patients including positioning, technical obstacles, reference data and post-processing and describing how to overcome some of these challenges. 1. Positioning: Many patients with syndromes, have scoliosis, para or quadriplegia, or contractures that make placing the patient on the table difficult. In these patients, imaging has to be adapted to the patients’ abilities and some components may need to be eliminated. With cerebral palsy and muscular dystrophy for example, the whole body and AP spine might have to be deferred and only a hip and forearm obtained. 2. Technical obstacles: There are many technical obstacles that can present challenges when performing DEXA scans on pediatric patients. Patients who have prostheses or metal rods present technical obstacles. There is no way to remove the metal artifacts in a whole body scan on these patients, so a hip or forearm might be the most accurate way to obtain the patient’s bone density due to this technical factor. 3. Reference Data: The reference data for pediatrics is limited in national data bases. For example, a total Z-score will not be factored for children under the age of 5 because there is not enough information in the national database for comparison. There is also not enough information on children of certain ethnicities. This presents a problem when diagnosing and treating children with abnormal bone density. 4. Post-processing could be different for each user. It can also be different for machines manufactured by different companies. For example, a machine made by Hologic might produce different numbers than a machine made by General Electric. Also, if the user does not place the post-processing tools the exact same way the prior user did, the results can vary. Overcoming some of these challenges has presented opportunities to grow. Sedation is used for children who may not be able to be perfectly still for a Dexa and positioning tools help on some of the more challenging patients. Learning how to work around prostheses and working with the ordering physicians and radiologists with the limited amount of reference data are a few ways of growing from these challenges. Placement of post-processing tools are the key to providing key information in comparing Dexa scans for patients who have them regularly for evaluations. Staff Education is the largest challenge to overcome. Read More

Idiopathic thickening of the pyloric muscle can occur in young infants, causing projectile vomiting, electrolyte abnormalities, and necessity for surgical intervention to relieve the gastric outlet obstruction. Case reports have been published describing infants with HPS who also have portal venous gas (PVG) visualized within the liver. The presence of PVG in other clinical scenarios often indicates a severe and potentially life threatening bowel condition. The purpose of this study was to determine the incidence of infants with hypertrophic pyloric stenosis (HPS) and concurrent portal venous gas (PVG), as well as whether there are unique clinical features or different outcomes in the HPS patients with PVG versus without PVG.
