Diagnostic Imaging refers to Xrays or other tests that provide information on the diagnosis, treatment and managment of illness and injury through the creation of an image. Imaging modalities available at CARE include ultrasound, digital radiography (Xrays), on-site CT including advanced imaging studies (CT angiography and myelography), and off-site MRI. The diagnostic imaging department at CARE is run by our Veterinary Radiologist, Dr Sandra Martig, who works closely with our specialists in internal medicine, surgery and emergency and critical care.

Radiographic Contrast Studies
Radiographic contrast studies are helpful to identify lesions in organs that are difficult to identify on plain radiographs. The urethra, for example, is a relatively thin tube of soft tissue that connects the urinary bladder with the outside world. The urethra is embedded in other soft tissue structures and cannot be identified on plain radiographs. However, when contrast medium is injected into the lumen of the urethra it is readily visible and can be assessed for diseases.
This male dog presented with blood in his urine (haematuria). He soon had almost constant bleeding independently of urination. Over the course of a few days he lost a significant amount of blood.
Contrast medium was injected into the urethra through a catheter for a procedure called retrograde positive contrast urethrography. A small area with less contrast, called a filling defect (arrow), was found near the flexure of the urethra where the urethra curves around the floor of the pelvis. A small growth was suspected and confirmed with an endoscope.
The growth was removed surgically. Histologic evaluation of the growth identified it as a benign polyp with a good prognosis. The dog stopped bleeding from his prepuce immediately after surgery and has recovered well.
