Head CT is not recommended as a first test to evaluate non-traumatic headaches in children unless the headache is acutely severe. While CT can provide important diagnostic information, they expose children to radiation and increase healthcare costs. The purpose of this investigation is to evaluate the association between insurance type and the likelihood of receiving a head CT scan for headache in a single pediatric hospital system. Read More

Pectus excavatum (PEx) is a chest wall deformity that leads to sternal depression and can impair cardiopulmonary function. CT imaging is used for surgical planning but exposes children to a significant radiation dose. Ultra-low dose CT enables PEx assessment in children with radiation exposure comparable to plain radiographs. The purpose of this study is to evaluate image quality and detection of thoracic pathology on ultra-low dose CT in children with PEx. Read More

The advent of fast CT scanners with lower radiation doses has resulted in rapid growth in the numbers of cardiac CTs being performed in children. This has also increased the number of CTs interpreted by cardiologists, similar to adult cardiac CT. Pediatric cardiac CT demonstrates multiple potential extracardiac variants and pathology that may occur in conjunction with congenital heart disease (CHD). Prior publications in adult cohorts demonstrate a wide-range and incidence of extracardiac findings (6-39%) but the prevalence in children is unknown. Therefore, the purpose of this abstract is to describe incidence, distribution and significance of the extracardiac findings found in pediatric cardiac CT at a tertiary referral center. Read More

Diffuse serosal and soft tissue enhancement (SSTE) is a unique pattern of contrast enhancement seen on abdominal radiographs after cardiac catheterization in newborns. While thought to be benign, SSTE can be misdiagnosed as pneumoperitoneum, resulting in unnecessary and potentially invasive diagnostic procedures. The purpose of this study is to describe the incidence of SSTE on abdominal radiograph performed in infants within 2 days of cardiac catheterization and identify clinical features associated with this imaging finding.

Developmental dysplasia of the hip (DDH) results from the abnormal development of the acetabulum, femoral head and mechanical instability of the hip joint. DDH often presents at birth, and if diagnosed early and treated successfully, children are able to develop a normal hip joint without functional limitation. If left untreated, DDH can lead to pain and osteoarthritis by early adulthood as well as discrepancy in leg length and functional disability. DDH risk factors include breech position in utero, oligohydramnios, female sex, primigravida, family history of DDH and improper swaddling. While there are recommendation for ultrasound screening in breech infants, only a few studies have dealt with the influence of gestational age on the development of DDH. Optimal timing of hip US and identification of patients who need follow-up are important to reduce unnecessary treatment and to avoid overtreatment. We aim to evaluate whether extremely premature infants (<28 weeks gestational age) warrant ultrasound screening for DDH in the absence of other risk factors. Read More

Magnetic Resonance Imaging is a powerful tool for the detection of ferromagnetic components. This property can be used for the early detection of pathologic conditions related to liver iron overload. Neonatal hemochromatosis and hemosiderosis are conditions associated with severe liver disease. Infections like parvovirus and cytomegalovirus, metabolic conditions and gestational allo-immune liver disease can produce neonatal hemochromatosis phenotype.
Fetal iron overload can be detected early by using T₂* multi-echo gradient sequence.
There are only few studies reporting standard T₂* values of the fetal liver at 1.5 T.
The aim of this study is to evaluated the standard T₂* values of the fetal liver using prenatal MRI with 3.0 T. Read More

Ultrasound is often the initial imaging modality in evaluation for pediatric appendicitis, but there is concern that the increasing prevalence of pediatric obesity may affect both the sensitivity of ultrasound and the interpretation of an equivocal result. We hypothesized that higher BMI percentile would correlate with lower ultrasound sensitivity, higher equivocal rate, and higher rate of CT acquisition.

The Wisdom in Diagnostic Imaging SIMulation (WIDI SIM) is a strategically designed computer aided simulation of an emergency imaging experience, which rigorously tests residents’ readiness to diagnose various Radiology emergencies. It has proven to be a reliable means for assessing resident preparedness to competently and independently cover radiology call. The residents are provided with a total of 65 cases of varying difficulty, including normal studies. The residents respond using free text which is then scored by faculty members utilizing a robust grading rubric. The identification of pertinent GU emergencies by the “on-call” resident is of the utmost importance as it the resident who must then notify the clinicians of this concern and so that emergent treatment can be expedited.

Approximately 800 children in the United States undergo renal transplant each year. Allograft failure is driven by interstitial fibrosis often due to chronic antibody mediated rejection. Renal biopsy is the gold standard to detect allograft dysfunction but limited by sampling error and inherent procedural and anesthesia risk. Ultrasound shearwave elastography (US-SWE) is a non-invasive imaging technique that assesses the mechanical stiffness of tissue. The primary aim of this study was to examine the relationship between US-SWE values, pathologic fibrosis/rejections scores and serology in pediatric recipients of renal transplant. Read More

ARPKD causes diffuse microcysts in the kidney parenchyma, and cyst burden cannot be quantified by standard image segmentation methods. We sought to assess whether apparent diffusion coefficient (ADC) measured by DWI could serve as a non-invasive biomarker of ARPKD severity, with the hypothesis that ADC would be higher in cystic vs. non-cystic parenchyma due to higher extracellular water content. We examined whether ADC could distinguish healthy kidneys from those affected by ARPKD, and whether a threshold ADC value could be established to differentiate cystic vs. non-cystic parenchyma.

The practice of performing dedicated breast ultrasounds in the pediatric emergency department varies according to institution. In the adult population, breast ultrasounds are commonly interpreted by dedicated breast imagers and/or radiologists appropriately qualified to interpret mammograms. Children's hospitals with dedicated pediatric radiology faculty are less likely to have such individuals on staff. This paper examines the practice of breast ultrasounds ordered in the emergency department throughout a large children's health system. Read More

Legg-Calvé-Perthes disease (LCPD) is juvenile idiopathic osteonecrosis of the femoral head, which can lead to permanent hip deformity and painful early-onset osteoarthritis. An issue in clinical practice is that there is wide variation in imaging and management of patients with LCPD. In our institution, we have created a rapid access pathway, so those with clinically suspected LCPD are imaged with a pelvic radiograph, seen by an orthopedic specialist in a dedicated LCPD clinic and subsequently a contrast MRI perfusion of the hips is expedited. This rapid pathway ensures imaging and management is not delayed. High quality MRI of the hips is important to prognosticate and guide orthopedic intervention. It was therefore important to standardise how the MRI hips is performed and reported. Read More

The tibiotalar joint is the third most common location for osteochondritis dissecans (OCD) lesions, which poses the risk of premature osteoarthritis, and often associates with a history of prior ankle sprains and fractures. Unstable lesions require surgical intervention. A 4-stage radiographic classification system has been previously proposed, but this system has a 50% false negative rate when compared to arthroscopic assessment (reference standard). Recently, MRI and arthroscopic findings have been correlated in adults, but no such validation study has been performed in children. Thus, the purpose of our study was to identify MRI findings that predict instability of OCD lesions of the ankle in children. Read More

The presence of a thin midline band or nodule like grey matter structure traversing the hypothalamic region on magnetic resonance imaging (MRI) is a recently reported neuroimaging finding. This has been termed as interhypothalamic adhesion (IHA). To date, no histopathological correlation has been published on the precise nature of IHA and whether it represents a developmental anomaly, cerebral malformation or the sequela of cerebral insult. We aim to look at a cohort of patients with IHA and determine its association with other cerebral anomalies seen in these cases. Read More
