ABSTRACT
Objective To assess the differential diagnosis and characteristics of renal benign and malignant tumors with three-dimensional contrast-enhanced ultrasound (3D-CEUS). Methods Totally 68 patients with renal tumors were examined by conventional ultrasound and two-dimensional contrastenhanced ultrasound(2D-CEUS). 3D imaging was reconstructed from 2D imaging, the differential diagnosis of renal tumors with 3D-CEUS was analyzed by comparing with 2D-CEUS. All patients with renal tumors were proved by operational pathology. Results Eighteen patients with renal benign tumors mostly displayed equal or low enhancement, showed "slowly in and slowly out" with 2D-CEUS, while displayed regular peripheral and internal vessels with 3D-CEUS. Fifty patients with renal malignant tumors mostly displayed high enhancement, showed "rapidly in and rapidly out" with 2D-CEUS,displayed winding peripheral vessels and disordered internal vessels with 3D-CEUS. 3D-CEUS may display the vascular characteristics of tumors and showed superior imaging quality to 2D-CEUS ( P < 0.05). Conclusions 3D-CEUS can display the vascular characteristics of tumors and their spatial positions, it plays an important role in differential diagnosis between renal benign and malignant tumors.
