Imaging involves the use of various techniques to build a 'picture' or 'image' of an area of concern. Radiography ( x-rays) and utrasonography (scans) are the most commonly used techniques, however MRI and CT scanning can also be utilised. At Parklands Veterinary Group, we use ‘state of the art’ digital equipment but also have vets with experience and trained in the fields of radiography and ultrasonography.
This involves the use of x-rays to create a 2 dimensional ‘shadow’ picture of tissues. X-rays are absorbed to different degrees by bodily structures, meaning that bone, tissue, fluid and air can be seperately identified. Many views are often needed to allow this 2D image to be interpreted into a 3D picture.
Using digital technology we are able to generate extremely high quality xrays with tremendous and consistent detail. This greatly helps in making subtle diagnosis in medical and orthopaedic conditions. Investment in this technology allows us the best chance of achieveing a diagnosis in complicated medical conditions.
This uses high frequency sound waves emitted from a handheld probe placed in contact with the skin to produce an image. Sound waves penetrate and reverberate from varying tissues to different degrees and this pattern enables the production of a 2 dimensional ‘slice’ of tissue visible on a monitor. The image is continual meaning it is possible to move the probe and gain an overall 3 dimensional assessment. Using advanced technology we are also able to watch directional blood flow and measure pressure gradients of fluid movement. An important advantage of ultrasonography is that it allows us to see into tissues, especially in the abdomen, often allowing biopsies to be taken with minimal distress to your pet. The ultrasound probe needs direct skin contact which means a small patch of fur must be shaved over the area of interest.
At Parklands we use modern, high quality equipment that is capable of producing images with superb detail.
Ultrasonography of the heart is another area of specialisation and is termed 'Echocardiography'.
Radiography and Ultrasound are not painful, but do require a relaxed and co-operative patient, so sedation or general anaesthesia will be required in order to get good high quality diagnostic xrays.
