Ultrasound
Ultrasound is a non-invasive imaging tool used to evaluate organ texture, detect masses, and guide needle aspirations. It plays a central role in diagnosing intestinal lymphoma and renal-lymphoma in cats, and in evaluating kidney structure in chronic-kidney-disease.
Key Facts
- Non-invasive; anesthesia rarely needed
- Can detect characteristic intestinal lymphoma bowel-wall changes
- Evaluates lymph node enlargement and organ texture (liver, kidneys)
- Guides needle aspirate biopsy of masses, lymph nodes, kidneys, and liver
- Intestinal lymphoma may be treated based on ultrasound findings alone (without biopsy) to reduce cost
- Kidney imaging is recommended in CKD to check for ureteral-stones and structural abnormalities
- Adrenal gland imaging distinguishes pituitary from adrenal cushings-syndrome (symmetry vs asymmetry)
- Assesses thyroid tumor invasiveness and surgical feasibility
- Species: dogs and cats
