Dynamic Three-Dimensional Contrast Enhanced Ultrasound with Quantification of Focal Liver Lesions

Three-dimensional contrast-enhanced ultrasound (3D-CEUS) combines the advantages of 3D ultrasound and contrast-enhanced ultrasound (CEUS). It can not only dynamically display the 3D enhanced structure of main liver vessels and focal liver lesions (FLL), but also their anatomical position relationship. It can be used for accurate positioning and noninvasive evaluation of liver tumors before treatment, so as to detect residual or recurrent tumors and improve the success rate of local treatment of the liver tumors. Dynamic 3D-CEUS with quantitative analysis is updated in recent years. Dynamic 3D-CEUS is technically feasible and can be used for clinical evaluation of the perfusion of FLLs avoiding adverse factors of sampling. The quantification of 3D-CEUS has shown promise in accurate assessment of focal liver tumor vasculature.
