Objective- To determine the possibility and reproducibility of three-dimensional ultrasonography (3DUS) and comparison of the achieved measurements to normal two-dimensional ultrasonography (2DCS).
Design- Descriptive study.
Animals- 10 young mixed normal dogs, age 1.5-2.5 year, weighing 9.7-12 kg.
Procedure- Renal width, length, and depth measured in coronal and transverse sections. The measurements were taken in both 2DUS and 3DUS scans. Each kidney was imaged five time s in coronal and transverse section and the measurements were recorded for each image. Statistical analysis-Descriptive analysis, paired t-test.
Results- The mean difference of the measurements obtained by 3DUS in compare with 2DUS was: 0.17em for renal length, 0.08 ernforrenal width, and 0.13 em for renal depth. There was no significant difference between 3DUS and 2DUS.
Conclusion and Clinical Relevance- In this study the correlation was seen between 3DUS and 2DUS.The3DUS method gives us extremely useful images for teaching and diagnosing purposes. The 3DUS image presentation can also be easily demonstrated in rotating 3Danimation.
