Study Notes
Ultrasound of the Stomach
- Position the transducer at the xiphoid and slide it caudally to visualize the stomach in short axis (transverse section).
- Assess the stomach in both long- and short-axis images for comprehensive evaluation.
- Sweeping the transducer toward the right side reveals the pyloroduodenal junction, noted as a thickened muscularis area between the pylorus and proximal duodenum.
- In cats, the submucosa appears hyperechoic due to fat deposition, making it distinctive on ultrasound images.
Ultrasound of the Urinary Bladder
- Position the transducer caudally in the central abdominal area for urinary bladder evaluation.
- Evaluate imagery in long and short axes, with attention to the trigone area, particularly its extension into the urethra or prostate gland in male dogs.
- Measurement for bladder volume can be calculated using the formula: Length x Width x Height x 0.523.
Ultrasound of the Left Kidney & Left Adrenal Gland
- Locate the left kidney by moving the transducer medially and slightly caudally from the spleen.
- Evaluate the left kidney in both long and short axes for complete assessment.
- Angle the probe medially from the left kidney to visualize the abdominal aorta in the long axis.
- The celiac and cranial mesenteric arteries, along with the left renal artery, delineate the area containing the left adrenal gland.
