Three-Dimensional Color Doppler Ultrasonography Study of Normal Liver Vascular Pattern in Dog

Objective- To create three-dimensional model of the dog's liver vessels by using threedimensional color Doppler ultrasonography which can be used for surgery planning, tumor detecting, transplantation, and other diagnostic or treatment project. Design- Descriptive study Animals- ۶ mixed breed dog, ۱.۶-۱.۷ years old, ۱۸-۲۰ kg weight Procedures- The liver was found by two-dimensional scan initially then threedimensional power and color Doppler scans were taken. Image acquisition was performed with reconstruction and simultaneous display of sectional anatomy in three orthogonal planes or any arbitrary oblique plane and also a ۳۶۰ degree rotating ۳D plane. Images were evaluated for gross anatomical visualizations and characters of the portal vein, caudal vena cava, hepatic vein and artery, and aorta in ۱۰ standard planes. Results- Three-dimensional ultrasound scans of the liver corresponding to the sagittal and transverse planes were found to be possible in ۶ planes in dorsal recumbency. Conclusion and Clinical Relevance- Three-dimensional color Doppler ultrasonography was used for dog liver and seems to have the potential to provide greater detail of the vascularity associated with abnormal lesion.
