The significance of bright bits in the pancreas. Ultrasound elastography (USE) in pancreatitis

Ultrasound elastography, or elastosonography, is increasingly available on high-end ultrasound machines;. At the most basic level USE gives an indication of tissue stiffness.  This may be either in response to mechanical pressure (strain imaging) or to ultrasound-generated compression (shear wave elastography).  Mechanical pressure in strain imaging is exerted externally (manually) or by internal changes due … Continue reading

I am starting to think that examination of the neck might be a useful part of the routine sonographic examination for cats and dogs: especially in complex cases.  In addition to those with sepsis, foreign bodies, thyroid disease, lymphadenopathy or salivary gland changes, patients with impaired oesophageal function are sometimes picked up.  Some animals with … Continue reading

Gastropathy caused by hypoadrenocorticism in dogs

I guess we know that hypoadrenocorticism (both ‘typical’ and ‘atypical’) is associated with gastrointestinal signs including ulceration.  I’ve not managed to find a completely convincing pathophysiological explanation of the mechanism for this.  However, I just wanted to share a couple of sonographic images of the stomach wall in addisonian dogs. They can be really striking. … Continue reading

SOFA vs SIRS and sonographic features of septic shock in dogs

In human medicine concepts in sepsis have evolved. SIRS: In 2016, a new consensus termed Sepsis-3 removed the concept of SIRS from the sepsis definition and replaced it with the SOFA (Sequential [Sepsis-Related] Organ Failure Assessment) score. The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). JAMA. 2016; 315(8):801-10 (ISSN: 1538-3598) Singer M; … Continue reading
