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
