HD x-rays - opinions wanted - Page 2

Stephenitz. great point to ask when the bitch was in season.  I hadn't thought of that.

DH,

Are you simply photographing the xray film against a window or over a lighted viewing box? I can't get anything (except black) by conventional scanning of the films--I don't have a negative scanner yet.

I have several xrays that I would like to share--taken at various ages--for OFA (good and excellent) as well as the "a" stamp.

Louise,

I have successfully taken digital photos of x-rays by taping them to a window.  You have to make sure there is nothing outside the window and also you don't want to be shooting into the sun.

Hope this helps.

Photograph x-rays against the light box at the vets, turn off flash, and if your camera allows for it set exposure to indoor lighting and reduce exposure a bit. Or, have someone hold the x-ray against the sky, or if no other person is handy tape it to a window. Make sure you only have sky in the background and as even as possible (trees and clouds and buildings will show otherwise). If your camera has a Macro setting (little flower) use it, that way you can get closer to the x-ray. If there is no Macro setting, stay 2 feet away from the x-ray or else it will get blurry. Make sure files do not get too large when putting them on here.  Number them so all which ones everyone is  talking about. And post one x-ray at a time or else it can quickly get too confusing.

I'll take a try...In the top xray I think the left femur head has some thickening of the neck and flatening of the head. The right is somewhat subluxated with also some flatening of the head. On a year old dog I think OFA Would give borderline. SV Noch zuglescent (sp).

The second xray the positioning is not as straight as it should be. The right hip is subluxated this could be due to the position because the left is in so much tighter or if bitch is in heat I'd say do over. I think OFA would say say a fair if this were a two year old dog with taking consideration of the positioning. But at a year old, borderline. SV fast normal or noch zuglescent.

Good thread!

I said the same exact thing as Trailrider on the other thread - took the words right out of my mouth.  I second exactly what Trailrider said.  Trailrider, do you trailride?  I do that, too - can't wait for fall to start cooling things off so I can get out on the trails again.

Am I dumb or am I dumb?? Geez, there's no need whatsoever to drag out the digital camera to photograph the xray against a light box or a window. Duh--all you have to do is scan the damned thing on a flatbed scanner without lowering the lid Here is Dog A's OFA xray at 2 years without anesthesia. This was a "reject" xray due to slight positional rotation.

2 Year old neutered (at 14 months) male, no anesthesia but was lightly sedated.  Sorry, I cut the knees off when I took the picture.  Barb

For DH's Dog number 1, I will stick by what I posted on the previous thread:

Yes, the positioning is great.

I would say that the dog would be rated as a "normal" or OFA "good" (possibly, but not likely, "excellent"). In my opinion, there is no joint laxity.  What Molly refers to as a "flattening" of the femoral head is entirely normal--depending of the age of the dog. If you drop an imaginary perpendicular line from the upper edge of the acetabular rim (and from a lateral aspect along the acetabular rim extending caudally towards the ischium), you will see that roughly three-quarters of femoral head is seated within the joint capsule. A two-thirds inclusion of the head is quite acceptable. Furthermore, the "lips" of the acetabulae are fairly well defined.

The flattened area (a fovea or "cup") is the fovea capitis femoris which serves as attachment (or provides an "origin") for the ligamentum teres femoris (also known as, the "ligamentum capitis femoris" or "round ligament of the femur"--a misnomer since the ligament is not round) to the acetabulum. This ligament does not stabilize the joint but provides "housing" for the femoral artery which originates at the obturator artery. This blood supply to the femoral head provided by the femoral artery is not necessary upon the completion of skeletal growth. The joint space is reasonably tight and uniform until it reaches the fovea.

Ideally, for the dog to receive a rating of OFA "excellent", the femoral necks could be longer. somewhat narrower, and more well-defined--the overall skeletal development could more pronounced. Over the yearsm I have had several dogs rated as OFA excellent".

I had a dog whose xrays (similar to the above) were almost not submitted to the OFA for the same reasons outlined by others. The dog's hips were rated as OFA "good".

LMP I tried that but mine came out black

I will try the window tomorrow
