Study Notes
Ultrasound of the Stomach
- Position the transducer at the xiphoid and slide it caudally to obtain a short-axis view of the stomach.
- Capture both long- and short-axis images of the stomach for comprehensive evaluation.
- When moving towards the right side, locate the pyloroduodenal junction, characterized by a thickened muscularis layer between the pylorus and proximal duodenum.
- In imaging dogs and cats, notice that the cat’s submucosa appears hyperechoic due to fat deposition.
Ultrasound of the Urinary Bladder
- Position the transducer centrally and caudally in the abdomen to assess the urinary bladder.
- Obtain both long- and short-axis images for complete bladder evaluation.
- Pay special attention to the trigone area, especially as it transitions into the urethra or prostate gland in male dogs.
- The bladder volume can be calculated using the formula: Length x Width x Height x 0.523.
