Abstract
B-mode ultrasound is routinely performed to evaluate the prostate gland in neutered dogs, although, the detection of malignancies may be challenging. Contrast-enhanced ultrasound (CEUS) has shown to be useful for the assessment of prostatic perfusion in normal and diseased dogs, although the interpretation of contrast ultrasonographic features may still be subjective. A quantitative tool for evaluating prostatic perfusion might improve the reliability of the results in terms of early detection of prostate neoplasia in neutered dogs. The present study aimed to evaluate the applicability of a postprocessing analysis tool to CEUS of the prostate in healthy neutered dogs, to provide quantitative measurements, and to study the influence of individual characteristics on prostatic regression. Twenty-three neutered dogs underwent a B-mode and CEUS examination of the prostate to acquire data about prostatic morphology and microcirculation. The prostate was imaged using a 5-7.5 MHz linear transducer and contrast was administered intravenously. Videoclips were analyzed by using Qontrast software and a postprocessing digital analysis tool (ImageJ) to measure perfusion peak intensity, time to peak, and vascularization ratio at the moment of the peak, which were then related to body weight, age, and time elapsed since orchiectomy. Correlation tests revealed higher vascularization in younger compared with older dogs (P < .05) and in smaller compared with larger dogs (P < .05). Time elapsed since orchiectomy (P > .05) did not affect prostatic perfusion. Contrast-enhanced ultrasound and the postprocessing analysis tool ImageJ allowed analysis of vascular perfusion in all dogs and have the potential to improve the diagnostic possibilities for andrological examination.
期刊介绍:
Veterinary Radiology & Ultrasound is a bimonthly, international, peer-reviewed, research journal devoted to the fields of veterinary diagnostic imaging and radiation oncology. Established in 1958, it is owned by the American College of Veterinary Radiology and is also the official journal for six affiliate veterinary organizations. Veterinary Radiology & Ultrasound is represented on the International Committee of Medical Journal Editors, World Association of Medical Editors, and Committee on Publication Ethics.
The mission of Veterinary Radiology & Ultrasound is to serve as a leading resource for high quality articles that advance scientific knowledge and standards of clinical practice in the areas of veterinary diagnostic radiology, computed tomography, magnetic resonance imaging, ultrasonography, nuclear imaging, radiation oncology, and interventional radiology. Manuscript types include original investigations, imaging diagnosis reports, review articles, editorials and letters to the Editor. Acceptance criteria include originality, significance, quality, reader interest, composition and adherence to author guidelines.
