Renal artery stenosis (RAS) is an important cause of hypertension in children. When suspected, imaging options include Doppler US, CTA and MRA. However, conventional angiography remains the gold standard. We investigate the accuracy and inter-reader reliability of CTA in children with suspected renal artery stenosis. Read More

Although ultrasound has advantages for bowel assessment in infants, the majority of bowel evaluation still takes place by radiograph. Although radiographic signs of advanced necrotizing enterocolitis (NEC) have been well documented, there is poor understanding of gas patterns in less severe NEC or other causes of feeding intolerance. Progressively abnormal appearance of gas patterns in NEC has been described, but it is unclear what role a gastric sump plays. Because a sump decompresses bowel and changes the gas pattern, its role in the progression of abnormal bowel gas patterns warrants attention. Read More

Neonates with prolonged hospitalization often require PICCs. The concern for PICC-related complications, including venous thrombosis, infection, catheter migration and breakage, often prompts Doppler ultrasound (US) evaluation. However, peri-catheter thrombus in a neonate can be challenging to evaluate, as the accessed peripheral veins in neonates are small, some less than 1mm in luminal diameter. Small-bore catheters may occupy the entirety of the vessel lumen, which can produce absence of peri-catheter flow, which is confounding for thrombus. This distinction has implications for hematologic management. Read More

Contrast-enhanced ultrasound (CEUS) and shear wave elastography (SWE) have been widely studied in adult thyroid disease. However, evaluation of thyroid nodules using these tools in pediatric patients has yet to be published. We aim to evaluate the feasibility and safety of CEUS and SWE for thyroid nodules in children at the time of cytologic biopsy. Read More

Fontan–associated liver disease (FALD) is associated with increased risk of liver cirrhosis and hepatocellular carcinoma. Liver biopsy is the current gold standard investigation for diagnosing liver fibrosis. Magnetic Resonance Elastography (MRE) is a non-invasive procedure assessing liver stiffness. To date, only limited published studies are available describing the correlation of MRE and biopsy in Fontan-associated pediatric patients. Further, longitudinal changes in MRE require an increase in hepatic stiffness of >22% to indicate true change in stiffness (95% CI). The purpose of this study is to determine the clinical implication of MRE in FALD. Read More
