With the Superb Micro-Vascular Imaging (SMI), the established Doppler technology has been extended by another mode. With this technique, microvascular structures with slow blood flow can now also be displayed in real time. As with the introduction of Doppler ultrasound, this new technique opens further diagnostic fields for the examiner, which were previously reserved for magnetic resonance imaging (MRI), computed tomography (CT) or contrast ultrasound (CEUS). Focal nodular hyperplasia (FNH) of the liver is characterized by a typical spoke-wheel vascular malformation (spoke-wheel sign, SWS) and
a good example using SMI for the diagnostic profit of our patients. The aim of this report is to describe the use of SMI as a new non-invasive, quick, and probably cost-effective diagnostic imaging tool
