Imaging-based algorithmic approach to gallbladder wall thickening

Figure 2 Contrast enhanced ultrasound in gallbladder wall thickening. A: Grey scale image shows asymmetrical mural thickening in the neck and body of gallbladder (arrows), short arrow shows the lumen of gallbladder; B: Image before contrast injection shows the baseline status of the gallbladder (arrows show the wall); C: Image at 17 s after contrast injection shows heterogenous mural enhancement (arrow); D: Image at 35 s shows washout (arrow). The infiltration of adjacent liver (short arrow) is well visualized on this image.
