Evaluating the alignment and blood flow in the femoral head in patients with congenital hip dysplasia following reduction is essential to the treatment of dysplastic hips. Current practice involves an immediate postoperative contrast enhanced MRI of the casted child to identify hips that may be at risk for avascular necrosis. Contrast enhanced ultrasound (CEUS) is an emerging imaging modality that is feasible to evaluate the perfusion of the cartilaginous proximal femoral epiphysis intraoperatively, after hip reduction and prior to spica casting. This educational exhibit describes the procedure of intraoperative CEUS of the hip from the sonographers’ perspective. Read More

Developmental dysplasia of the hip (DDH) is the leading cause of hip disease in infants. AVN is a potential complication of treatment for DDH, which is traditionally diagnosed on follow-up pelvic radiographs. But classic radiographic findings of AVN may be radiographically-occult for months to years after surgery. To investigate the performance of gadolinium-enhanced magnetic resonance imaging (MRI) for predicting avascular necrosis (AVN) of the femoral head following surgical hip reduction for developmental dysplasia of the hip (DDH) using qualitative and quantitative methods.

It is essential that budding pediatric radiologists have well-honed ultrasound (US) skills in order to provide correct image interpretation and excellent patient care. The lack of hands-on US experience is a critical gap in current radiology training. We sought to create an interactive, portable tool to remedy this issue. Read More

Conventional Doppler US is known to have low sensitivity for the diagnosis of renal artery stenosis (RAS), in particular segmental renovascular disease. This study aims to determine if contrast-enhanced US (CEUS) can quantitatively provide assessment of renal arterial and parenchymal perfusion pre- and post- renal artery angioplasty in children and potentially be used as a follow-up imaging tool.

Assessment of fluid overload in hemodialysis patients is usually based on a patient’s ideal weight which presents a challenge, especially in children due to normal growth and development. Noninvasive, validated sonographic fluid balance measurements could potentially guide fluid removal in children undergoing hemodialysis. We examine changes in IVC diameter and lung b-lines in children pre- and post- dialysis. 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

There is no standardized system for assessment of which pediatric tumors are amenable to partial nephrectomy – a surgery that is considered in pediatric patients with bilateral renal masses and those with predisposition syndromes. The RENAL Nephrometry score is the most widely used system to assess renal tumor complexity for surgical decision making in adults. We evaluated the RENAL Nephrometry score and imaging features that might predict perioperative clinical outcomes. Read More

Volume overload is linked to increased cardiovascular morbidity and mortality in children receiving hemodialysis (HD). Clinician assessment of volume status lacks accuracy and has substantial inter- and intra- observer variability. We investigated the use of ultrasound (US) skin thickness, and muscle elastography in pediatric HD patients. Read More
