Diagnostic imaging of the canine prostate gland subject to its location and size

The objective of the present research was to assess the usability of three diagnostic imaging modalities for canine prostate gland evaluation. The studies included 33 male dogs of various breeds. A radiographic diagnostic procedure was employed as well as dual modality ultrasound imaging, i.e. transabdominal (TAUS) and transrectal (TRUS). Radiograms were studied to evaluate the prostate gland size and localisation. Both ultrasound imaging techniques were compared regarding the imaging of various prostate parenchyma areas. It was found that a suitable USG modality should be tailored to the prostate size and localisation. The TRUS technique proved to be most helpful in visualising the gland localised in the pelvic cavity, while the TAUS scanning for the enlarged, displaced cranially prostate.
