Virtual navigation assisted contrast-enhanced ultrasound for focal liver lesion
虚拟导航超声造影定位检出肝脏局灶性病变的价值

Objective To evaluate the use of virtual navigation in assisting contrast-enhanced ultrasound for focal liver lesion.Methods Forty-seven cases of invisible focal liver lesions by B-mode ultrasound were identified by CT/MR.Image fusion of CT/MR and ultrasound images were achieved by virtual navigation,and virtual navigation assisted contrast-enhanced ultrasound was performed.The percentage of successful image fusion and the time for image fusion,as well as the result of virtual navigation assisted contrast-e...
