The objectives of this two\u2010part, observer agreement, methods comparison study were to assess observer agreement and the effects of varying CT technical parameters for volume measurements of canine prostate glands on CT images using OsiriX<jats:sup>\u00ae<\/jats:sup> DICOM viewer software. In the first retrospective study, two observers measured prostate volumes of 13 client\u2010owned dogs thrice on noncontrast and contrast CT images. In the second prospective study, two observers measured the prostate volume of 10 cadavers using five different CT protocols and eight cadavers using three slice thicknesses. Observer agreement analyses were performed, and prostatic CT volume measurements were compared with water displacement volume measurements. Intra\u2010 and interobserver variability and the effect of contrast enhancement were found to be minimal when a one\u2010way analysis of variance model and intraclass correlation coefficients were used. No significant differences emerged between different protocols and slice thicknesses using a linear mixed effects model. When the prostate CT volume was compared using a Bland\u2013Altman plot with the reference volume acquired by the water displacement method, agreement without consistent bias between the methods was shown, and over 90% of measurements were located within the 95% limits of agreement. The findings supported using OsiriX<jats:sup>\u00ae<\/jats:sup> software for CT prostatic volume measurements in dogs.<\/jats:p>","DOI":"10.1111\/vru.13125","type":"journal-article","created":{"date-parts":[[2022,7,5]],"date-time":"2022-07-05T15:54:57Z","timestamp":1657036497000},"page":"729-738","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["CT
