Abstract: Objective To evaluate the safety, feasibility and clinical value of real-time navigation system with CT/MR and sonographic images for percutaneous ablation of hepatic malignancies poorly defined on conventional ultrasonography. Methods Fifteen patients with 22 hepatic malignant lesions underwent percutaneous ablation guided by virtual navigation system with ultrasonography. Treatment response was assessed by the contrast CT/MR followed up one month after procedures. Results Complete tumor necrosis was achieved in 20 lesions, but 2 lesions showed residual tumor in the ablation zone. No treatment associated complications were found. Conclusions The application of virtual navigation system is of clinical value in localization of lesions, guidance of biopsy and assessment of the interventional therapy in patient with hepatic malignancies, particularly for those with poorly identified lesions by conventional ultrasonography.
