Radiograph of pedis

Well with parasites out-of-the-way I can now focus on my main exams from the last semester. I am going be doing these over the next month as I start the summer semester as I think the summer exam period will be bad enough without any extra exams to do from last semester.

So now all I have remaining to do is Anatomy, Nutrition, Radiology and Imaging Diagnostics. I am choosing to do my radiology exam next as this is something I already know a bit about so will be easier to study for, and as I only have 5 days in which to do my studying the most sensible option.

I think I’ve spoken about some of what actually goes into this module previously, however it includes both radiography (x-rays) and ultrasound as well as a little bit of MRI and CT. Now basically from the 13 weeks of teaching we are supposed to know everything that could possible show up either on a x-ray or an ultrasound.

Being good at radiography basically means being good at anatomy, unless you know where things are and what they are supposed to look like you cannot read an image. And even more important is considering the entire image. I have heard rumours of a radiology professor who has a x-ray from a dog hit by a car which has caused many students to fail. This radiograph shows the dog as having obvious fractures in the pelvic region which attracts the student’s attention, however on looking closely the intestines are no longer in the abdomen. The dog has also suffered a diaphragmatic hernia (a hole in the diaphragm) with the intestines taking up space in the thorax and compromising the dogs breathing…

Now fractures are painful, and can look very nasty, however bones heal very slowly. However a dog that can’t breathe properly, is a dog that is an emergency as not breathing will kill very quickly.

The second part of the exam is ultrasound which is specifically difficult as it requires not only looking at the screen but a thorough understanding of anatomy and where the probe is on the body to be able to determine what the mess on the screen actually means. Positioning of the probe is crucial as being a cross-sectional image having the wrong rotation of the probe can mean that things are completely missed.

For now I am going back to my studying, at the moment I am reading up on contrast radiography which allows us to use special materials to improve the radiographic appearance of organs.
