Abstract
Objective: To compare the value of three-dimensional CEUS (3D-CEUS) and three-dimensional color power angiography (3D-CPA) in evaluating blood supply of renal tumors. Methods: One hundred and twenty-one patients with renal tumors confirmed by pathology underwent 3D-CEUS and 3D-CPA after conventional ultrasound and CEUS. Analysis was performed using QLab software. Renal tumors were categorized into 4 grades based on the blood supply assessed by 3D-CEUS or 3D-CPA. Blood supply of renal tumors was compared between 3D-CEUS and 3D-CPA. Results: Benign and malignant renal tumors showed significant differences in blood supply in the different phases of 3D-CEUS (all P <0.05), but not of 3D-CPA (P > 0.05). Malignant renal tumors showed abundant blood flow, tortuous expansive reticulation or irregular messy dendritic arborization, while benign renal tumors showed less blood flow, nebulous or reticular on the basis of nebulous. Moreover, blood supply of renal tumors during early parenchymal phase assessed by 3D-CEUS correlated well with 3D-CPA (P <0.05). Conclusion: Three-dimensional ultrasonography can depict clear stereoscopic structures and morphological characteristics of renal tumors. 3D-CEUS is superior to 3D-CPA in assessment of blood supply of renal tumors.
