Left parasternal short-axis scanning technique
Figure 5.6. Left parasternal short-axis scanning technique. The transducer is positioned near the left cranial border of the heart. Cranial-caudal yields the series of short axis (SAx) images. Variable angulation in the dorsal-ventral direction may be necessary as suggested by the figure. 1: Left parasternal short-axis (LPS SAx) view at the right ventricle (RV) inflow tract. The right coronary (RC), left coronary (LC), and non-coronary (NC) cusps of the aortic (Ao) valve may be visible. 2: LPS SAx view at the RV inflow-outflow tracts. Both the inflow and outflow tracts of the right heart may be visible with subtle angulation and twist adjustments. The RC, LC, and NC cusps of the Ao valve may be visible. 3: LPS SAx view at the pulmonary trunk (PT). Division of the PT into the right and left main pulmonary arteries is seen in the far field.

Look, I’ve got a brand new ultrasound machine !
Can you imagine that this is what vets had to work with not too long ago? 😉
Things have changed for the better over the last 15 years. Aren’t you hectic to see what the future holds for us? I am.
What kind of machine are you working with these days? If you think we missed an important one, let us know and we’ll add it to the list. And don’t hesitate to share your experience here or on our Facebook page.

Normal anterior segment of the eye
From Chapter 2 – Eye and Orbit
Figure 2.8. Normal anterior segment of the eye A: Schematic drawing of the anterior segment of the eye. C, cornea; AC, anterior chamber; I, iris; PC, posterior chamber; L, lens; VB, vitreous body; CB, ciliary body. B: High-resolution (12 MHz) sonogram of the cornea, anterior and posterior chambers, ciliary bodies (CB). The cornea appears as 2 discrete hyperechoic curvilinear interfaces (arrowheads). CB, ciliary body; VB, vitreous body. (*) indicates to the posterior chamber. C: Normal cornea (between arrowheads) and anterior chamber imaged (AC) with a 35MHz probe in axial section. The iris and the anterior lens capsule are in mutual contact D: Perilimbal radial section with a 35 MHz probe. The ciliary cleft is visible and normally open (red asterisk). The corneal-scleral junction (arrows), anterior chamber (AC), anterior lens capsule, part of the iris and the posterior chamber (white asterisk) can be seen.

Adrenal nodules and masses in four dogs
From Chapter 12 – Adrenals
Figure 12.10. Adrenal nodules and masses in four dogs. A: Sagittal sonogram of the left adrenal gland of a Toy Poodle with pituitary-dependent hyperadrenocorticism. Note the hyperechoic nodules in each pole of the gland, which is thickened (up to 10.4mm). B: Sagittal sonogram of the left adrenal gland of a Mountain Bernese dog with histiocytic sarcoma. A 2cm nodule is identified in the caudal pole of the adrenal gland, deforming the adjacent left renal vein (LRV). Fine-needle aspiration of the nodule confirmed metastasis. C: Transverse sonogram of an adenocarcinoma of the left adrenal gland in an 11-year-old large-breed dog. A large, irregular, inhomogeneous mass (arrowheads) has replaced the left adrenal gland. This mass contains amorphous mineralization, as seen as shadowing hyperechoic foci (arrow),There was no sonographic evidence of vascular invasion, although caudal displacement and compression of the left renal vein (RV) is seen. Sp, spleen. D: Sagittal sonogram of a pheochromocytoma in a 8-year-old boxer crossed. A large inhomogeneous mass is identified medial to the left kidney, but not invading the adjacent vessels.

Carcinomatosis and sarcomatosis
From Chapter 15 – Abdominal Cavity, Lymph Nodes, and Great Vessels
Figure 15.17. Carcinomatosis and sarcomatosis. A and B: In these two cats with pancreatic adenocarcinoma, nodules of variable echogenicity are disseminated in the omentum and mesentery. C: In one of these cats (same as in A), hypoechoic nodules also invade the peritoneal lining and adjacent abdominal wall. D: In this dog with undifferentiated soft tissue sarcoma, masses were found throughout the abdominal cavity, consistent with sarcomatosis.
