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.

MR elastography (MRE) is increasingly being used to non-invasively assess diffuse liver disease in children. However, there are limited normal liver stiffness data for MRE in children. The purpose of this study was to determine normal liver stiffness measured by MRE for children and assess for associations with demographic factors, MRI field strength and MRI vendor. Read More

Compressed SENSE (CS) facilitates significantly shorter MRI acquisition times. There is a paucity of data comparing quantitative MRI with regularly under-sampling schemes like SENSE to pseudorandom under-sampling schemes like CS. The purpose was to compare measurements of liver proton density fat fraction (PDFF), T2*, and stiffness between SENSE and CS techniques with identical MR acquisition parameters. Read More

Sinusoidal obstruction syndrome (SOS) is a potentially fatal disease affecting children following bone marrow transplantation (BMT). SOS diagnosis is clinical because traditional ultrasound has poor sensitivity and specificity with portal vein flow reversal occurring well after the disease is clinically evident. Ultrasound elastography is a newer technology that measures liver stiffness, which should increase in SOS due to passive hepatic congestion. Our hypothesis is that quantitative shear wave ultrasound elastography will be more accurate in detecting this disease compared with conventional ultrasound parameters. Read More

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

Ultrasound shear wave elastography (US SWE) can be used to noninvasively measure liver stiffness. US SWE is a potentially useful technique for diagnosing and monitoring liver fibrosis, obviating the need for liver biopsy in some patients. When compared to MR elastography (MRE), US SWE is lower cost, portable, and does not need sedation/anesthesia. US SWE measurements can vary by method (point vs. 2D) and vendor. Few studies have defined cut-off values for detecting fibrosis in pediatric patients using US 2D SWE. This study aims to evaluate the diagnostic performance and define cut-off values of US 2D SWE for the detection of liver fibrosis in pediatric patients, using Toshiba (Canon) Aplio 500 and Aplio i800 systems.
