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 threedimensionalcolor Doppler ultrasonography which can be used for surgery planning,tumor detecting, transplantation, and other diagnostic or treatment project.Design- Descriptive studyAnimals- 6 mixed breed dog, 1.6-1.7 years old, 18-20 kg weightProcedures- The liver was found by two-dimensional scan initially then threedimensionalpower and color Doppler scans were taken. Image acquisition was performedwith reconstruction and simultaneous display of sectional anatomy in three orthogonalplanes or any arbitrary oblique plane and also a 360 degree rotating 3D plane. Imageswere evaluated for gross anatomical visualizations and characters of the portal vein,caudal vena cava, hepatic vein and artery, and aorta in 10 standard planes.Results- Three-dimensional ultrasound scans of the liver corresponding to the sagittal andtransverse planes were found to be possible in 6 planes in dorsal recumbency.Conclusion and Clinical Relevance- Three-dimensional color Doppler ultrasonographywas used for dog liver and seems to have the potential to provide greater detail of thevascularity associated with abnormal lesion.
