Spleen and Liver Stiffness Evaluation by ARFI Imaging: A Reliable Tool for a Short-Term Monitoring of Portal Hypertension?

Figure 4

Considering significant variability of spleen stiffness results across the spleen, repetitive spleen stiffness measurements (SSM) were performed in three different sections of the spleen in the baseline and follow-up visits and respective delta results were calculated for every third of the spleen. The ARFI results were assessed in the upper, the hilar, and the bottom section (schematic image of the three spleen sections separated from each other) (ARFI = acoustic radiation force impulse imaging; SSM = spleen stiffness measurement).
