  1. Ultrasound of the Kidneys Wendy Blount, DVM Click on the blue arrow at bottom left or hit the “return” key to advance the show (mouse over to reveal) Free PowerPoint Templates

  2. Transition Adjustments • Depth – relatively superficial on the right, left varies • Frequency – varies 5-7.5 MHz (higher for smaller pets) • deeper penetration for large dogs comes at the expense of detail • May need lower frequency than bladder and gut • Gain and Contrast – usually no change from liver & spleen • TGC – adjust as needed Free PowerPoint Templates

  3. Landmarks for Kidneys • Left Kidney – location variable – caudal to left costal arch • Spleen serves as an acoustic window • Caudal to the stomach • Dorsal and medial to the spleen, caudal to the spleen head • Right Kidney - usually cranial & dorsal to the left kidney • Follow the caudate lobe of the liver caudally until you find it • Or start at the dorsal aspect of the right costal arch, rocking the probe cranially • Caudal to pylorus & liver, adjacent to the duodenum Free PowerPoint Templates
