Ultrasonic findings of osteosarcoma by three-dimensional color power angiography / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the value of three-dimensional color power angiography(3D-CPA,) in osteosarcoma diagnosis. Methods Forty-three cases with osteosarcoma were detected with 3D-CPA to assess the vascular classification(3D-CPA Ⅰ to Ⅲ) and measure the vascular parameters including vascularization index(VI), flow index(FI) and vascularization-flow index(VFI). Results All of the 43 cases were classified into 3D-CPA Ⅲ type. The space structure shape of blood vessels and the origin of nutrient vessels was clear. The quantitative measurement showed that VI was 25.84±6.87,FI was 34, 18±2.93, VFI was 9.02±4.04. Conclnsions It is a new method to analyze and diagnose osteosarcoma with 3D-CPA because it can show the nutrient vessels and the embranchments of blood vessels clearly, tridimensionally and integrally and Bake quantitative or partial-quantitative analysis.
