Can Nonfibrotic Nonalcoholic Steatohepatitis Be Effectively Identified by Supersonic Shear Imaging?

Figure 1

Share wave elastography of the rabbit liver. (a) After overall observation of the two-dimensional grayscale images of the rabbit liver, the line array probe (SL10-4) of an Aixplorer ultrasound imaging system was fixed lightly on the rabbit skin with the target liver lobe as the detection site. (b) Before the SWE test, the measurement section can be preselected by the two-dimensional grayscale image. (c) When the SWE mode is started, the screen displays a double frame. The two-dimensional grayscale diagram is used to guide the placement of ROI (square), and the gallbladder, biliary tract, and blood vessels shall be avoided. In the ROI is a real-time color map showing liver elasticity. After the color signal in the ROI is filled by more than 90% and stabilized, the Q-Box (circle) is activated to measure the elasticity value and the result is displayed on the screen. SWE: share wave elastography; ROI: region of interest.
