Spleen Stiffness measured by point Shear Wave Elastography (pSWE) – Comparison between VTTQ/Acoustic Radiation Force Impulse (ARFI) and ElastPQ

Purpose: A comprehensive comparison between Acoustic Radiation Force Impulse (Siemens Acuson S3000) and ElastPQ (Philips EPIQ 7) by means of spleen stiffness (SS) measurement. Standard values of spleen stiffness measured with pSWE until today have been generated solely by means of ARFI. In former studies, measurement of SS is recommended in the lower pole of the spleen. Material and methods: In 200 healthy subjects (78 male/122 female, mean BMI 22.56 ± 2.57 kg/m2, mean age 27.93 ± 8.13 years, mean fasting time = 3.74 ± 1.84 hours) SS was measured in 3 defined regions of the spleen using VTTQ/ARFI and ElastPQ (lo…
