Surgical intervention for hepatobiliary diseases is challenged by the limitations of individual medical imaging modalities,which often suffer from reduced accuracy and insufficient diagnostic detail.Cur-rently,ultrasound combined with CT or MRI image fusion navigation technology is widely used in clinical settings.In hepatobiliary surgery,the use of ultrasound combined with CT or MRI image fusion navigation technology offers several advantages over single ultrasound,CT,and MRI images.It improves the real-time capability and accuracy of images,provides reliability for the surgical treatment of hepatobiliary diseases,and aligns more closely with the concept of precision surgery.
