This guide is based on meta-analysis and clinical studies using Siemens Healthineers Ultrasound. This guide is not intended to be used as a conversion table for liver stiffness readings to fibrosis stage or replace the performing physician’s judgment for the final diagnosis. Rev: April 2021 †, †† Data on file. Technique: spin-5.8 cm • Fasted patient lies in a slight left lateral decubitus position • Place ROI optimally within segment 5 or 8 of the liver. Avoid increased subcapsular reverberation by placing the ROI perpendicular to and at least 1.5–2 cm below the liver capsule. This can be achieved by placing the 2 cm cursor depth marker on the liver capsule. • Instruct patient to maintain shallow, brief breath hold • Obtain 10 measurements at the same site a. At least 6/10 of measurements should be “valid” as indicated on the bottom of the screen, as seen here Site 1: 0 Valid/0 Total b. IQR / Median ratio of ≤ 0.15 (m/s) and 0.3 (kPa) is the recommended quality control measure for adequate technical quality (as calculated on the report page IQR/Median ) For more information, please visit siemens-healthineers.com/ultrasound or contact your local Siemens Healthineers sales representative.
