Double contrast-enhanced two-dimensional and three-dimensional ultrasonography for evaluation of gastric lesions

Figure 4 Double contrast-enhanced ultrasound imaging of gastric stromal tumor. A: Two-dimensional double contrast-enhanced ultrasound (DCUS) images displayed a anechoic mass into the gastric cavity in oral contrast ultrasonography (right figure), from which we hardly judged whether it was cystic or solid lesion; but the intravenous contrast imaging (left figure) showed there was contrast agent enhancement in the focus of infection (arrow); B: Three-dimensional DCUS imaging displayed the tumor elevated to the gastric cavity (arrow).
