Staging liver fibrosis after severe yellow fever with ultrasound elastography in Brazil: A six-month follow-up study
Fig 2
Right upper quadrant ultrasound of two patients using point shear-wave elastography technique.
(A) A 48-year-old male patient, and (B), a 38-year-old male patient, both asymptomatic, 6 months after onset of severe yellow fever. Images depict placement of regions of interest (ROIs) on the right lobe of the liver at expiratory breath-hold. Shear-wave velocities (in m/s) were generated, with corresponding liver stiffness values after multiple measurements of 5.3 kPa and 4.6 kPa, respectively. Both subjects were then classified as F0/F1 on the Metavir scoring system for staging of fibrosis. RMI = Reliability measurement index.
