Fig. 3. Measurement performed in the "b" position using the ultrasound-derived fat fraction algorithm implemented on the Sequoia ultrasound system (Siemens Healthineers, Erlangen, Germany).

The value is given as the percentage of fat (%) and it is not shown when the software judges that the quality of the acquisition is low: in that case, an "XXX" sequence instead of the percentage appears on the monitor.
