In cats, the celiac and cranial mesenteric arteries are used as the target vessels for finding the left adrenal gland. Identification of the left phrenicoabdominal vein along the ventral (near field) margin of the middle of the left adrenal gland is confirmation that you are evaluating the left adrenal gland. Once you have the caudal pole of the left adrenal gland, rotate the transducer in a clockwise direction from 12 to 1 o’clock (about 10°) to bring the left adrenal gland into long axis ( Figure 1). Often you will find the caudal pole of the left adrenal gland and 2 of those arteries all 3 arteries will not necessarily be in the same imaging plane. Angle medial (nondistance motion) to the level of the aorta and find the celiac, cranial mesenteric, and left renal arteries. ![]() In dogs, the transducer motion for finding the left adrenal gland starts lateral in the long axis of the left kidney. ![]() ![]() The left phrenicoabdominal vein, seen in the near field or ventral aspect of the adrenal gland and transecting it into equal cranial and caudal poles, 1 is an inconsistent finding using gray-scale 2D imaging but, when present, helps confirm the localization of the left adrenal gland.
