Is it possible to diagnose food allergies in dogs/cats with ultrasound, ie measuring PI, RI of the celiac and cranial mesenteric arteries?

Wow tough question t start
Wow tough question t start the post:) I have heard of some people playing around with this but i have not heard of anything definitive or reliable. My personal opinion is that there are too many variables in the mesenteric vasculature that are affected by volume contraction as the Gi tract is a “shock organ” and after the spleen has dumped its volume in a dehydration state then the body takes the volume from the Gi tract. Assuming the patient is fully hydrated then that variable can be minimized but what is the scenario if the patient is on fluid therapy for example?? I am a tissue guy and ideally sampled through intraoperative ultrasound if there are any Gi lesions that may or may not be seen by the surgeon given that they are often mural lesions that do not show anything in the serosa for the surgeon to target. Click here and see this study we did in cats for example ecvim number 3 2009. Then …..what is food allergy and what is IBD….???? The easiest thing is a 6-8 week elimination diet an tx parasites which resolves most cases that dont have major IBD patterns on ultrasound in my experience. the most important sonographic finding in my opinion is whether there is loss of detail or not in the bowel wall and what is the muscularis/mucosal ratio and what are does the submucosal (holding layer) look like? measuring Gi can be variable as well as its such a dynamic organ and changes all the time depending on ingesta transit. hydration status and so forth. Hi resolution Gi imaging has tons more value in my experience than measurements in this organ. Its not like measuring a kidney that doesnt move. My 0.6 cm bowel may be another sonographers 0.8 cm bowel depending on where we both measured and what was the hydration and ingesta state of the patient. I think the measurements you are talking about would follow with this variability as well regarding the angle the measurement was taken, hydration and ingesta transit status and so forth…not to mention time consuming. I dont see it as taking on a solid following any time soon. i know this may have been a long winded answer but the subject touches a wide spectrum. Does anyone else have experience with this?
