Another thing, as I'm ultrasounding 7...8 mares in a day, it seems to me that every mare's ovaries look the same. The same three or four follicles. One really round one then a more flat squishy one, then another really round one. The round ones don't grow too much. It's always the one in the middle.
One more thing. LOL. When I'm on the ovary and I move my probe back and forth, trying to position it, putting a little pressure on it, the follicles all go bleh. They squish and flatten. They all melt together and get huge. I have a bit of trouble getting them to look round and measurable. Is this normal? They will look like this and then once I get my probe settled and twisted a little bit, then I can measure them, but it's a little difficult. I guess I'm just second guessing my measurements. Should I be measuring when I did? (In the previous pic) Here are some more pics to help show what I'm talking about when the follicles all go together. These pics are in step by step order to what happens on the screen.
See how they squish? Do I need to worry about that at all? LOL. Is the middle follicle good? Because that's the one that I'm usually measuring because it's always the biggest.
Anyway, thanks for any help you can give. And like I said in another thread...I am very comfortable do this on my mares. I go slow and gentle. I am just really trying to learn and make SURE what I'm looking at onscreen. I hate second guessing myself with the follicle measurements. Sorry the pics aren't the greatest. When I'm actually moving the probe the picture is much clearer. Thank you!!!
The clarity of the images on your ultrasound machine are not great, so that coupled with the fact that they are not presented in "real time" makes it a little difficult to give an honest opinion, but...
in those pics I can see the uterine horn and then what looks like a triangular section of fluid
I doubt that you are actually looking at fluid in the uterus. It appears that it may be outside the uterine region.
Am I on the ovary? Should I just trust the machine and measure the follicle? And not worry about them looking the same? It's still early in the year up here in Washington state, maybe my mares are still transitional? And that's why the mares ovaries look similar?
It would be unlikely that all the ovaries would look exactly the same. They may have similarities, but to have 7-8 mares identical seems a little too much of a coincidence. Looking at the one image - again given my observations made about about clarity and lack of real time - while it definitely could be an ovary, it could also be a view of something else external to the ovary/uterus.
When I'm on the ovary and I move my probe back and forth, trying to position it, putting a little pressure on it, the follicles all go bleh. They squish and flatten
Follicles very close to ovulation often become extremely soft, but if all of the follicles are doing this then you are probably looking at something other than a follicle! Looking at the last 2 images above (C1/D1) I have severe doubts that what you are looking at is an ovary - there shouldn't be a large area of anechoic material (fluid?) immediately above and taking up most of the screen. You might also want to look at the article we have about signs of impending ovulation which might help you a bit. The images were taken with a Sonovet 2000 ultrasound machine from Universal Ultrasound and give more clarity than you have with your machine, so that might help you to see what to expect a bit better as well.
Arabians will not present with any significant difference from other breeds.
Sorry not to be of much assistance here, but unless one is looking over someone's shoulder as they do it, it's difficult in many instances to truly identify what is being looked at - I don't even know how far your hand is in the mare, never mind at what angle! I think you would probably benefit by finding an ultrasounding course to go on, as I suspect you are "shooting in the dark" to some extent!
Ok, thank you so much for all the input, Jos! I scanned some more mares and realized that most of the time, I wasn't even on the ovary. I did find them some of the time and that's why my wonder of - am I on the ovary in those pics? They just didn't look right, but I couldn't find the actual ovary so I assumed that I was finding it. LOL. Some ovaries are really tricky to find!
Anyway, I have had a few more days of scanning and figured out how to get the ovary to pop up when it's hiding behind that horn. I also spoke with my vet and he showed me how to find those ovaries easier.
It does look much better in real time. I am positive I was on the ovary in the second two pics, too. The follicle in those two pics aren't as big as they really were because I wanted to take a picture of the entire ovary (or at least more than one follicle) as soon as I unfroze the screen the follicle popped back up and I measured it. It looked just like the first picture.
Thanks for the input, Jos! It is very much appreciated!
