Ultrasound-guided biopsy is a good and feasible technique in dogs. Although we have only used it for biopsy of liver and kidney, it can have further uses. In our use of ultrasound-guided biopsy of kidney and liver, we have found that we can achieve adequate biopsy samples using the Franklin modified Vim-Silverman and Tru Cut biopsy of kidney and liver. The fine-needle biopsies of the liver were adequate for examination of hepatocytes but inadequate to evaluate structure owing to small size of the sample. In contrast, the renal fine-needle samples were both poor in quality and quantity. This technique has the advantages of being noninvasive, quick, and easy, and it can be performed with the patient under local anesthesia. It has an advantage over blind percutaneous biopsy because the needle can be visualized in the organ and the organ scanned after biopsy for possible complications. Another advantage is that, unlike other radiographic biopsy procedures, ionizing radiation is not used for imaging.
