Supersonic® (SuperSonic Imagine, Aix-en-Provence, France) is part of the latest generation of elastography devices and is based on ultrafast shearwave elastography (SWE) technology. This device is a conventional ultrasound system for routine ultrasound scanning with an integrated module for measuring tissue stiffness, and has the advantage of establishing real-time mappings of tissue rigidity over a large area. Several studies have shown that the measurements were reliable and reproducible, especially in the assessment of liver stiffness. In the literature, only one study addressed the measurement of hepatic rigidity with the Supersonic® ultrasound system in liver transplant patients and was designed to diagnose viral hepatitis recurrence or acute cellular rejection. In the secondary results, the authors found a significantly higher hepatic rigidity of healthy hepatic grafts compared to healthy native livers.
