A prospective pilot study enrolling six dogs with nasal neoplasia was performed with CT and MRI studies acquired under the same anesthetic episode. Interobserver comparison and comparison between the two imaging modalities with regard to bidimensional measurements of the nasal tumors, tumor staging using historical schemes, and assignment of an ordinal scale of tumor margin clarity at the tumor\u2010soft tissue interface were performed. The hypotheses included that MRI would have greater tumor measurements, result in higher tumor staging, and more clearly define the tumor soft tissue interface when compared to CT. Evaluation of bone involvement of the nasal cavity and head showed a high level of agreement between CT and MRI. Estimation of tumor volume using bidimensional measurements was higher on MRI imaging in 5\/6 dogs, and resulted in a median tumor volume which was 18.4% higher than CT imaging. Disagreement between CT and MRI was noted with meningeal enhancement, in which two dogs were positive for meningeal enhancement on MRI and negative on CT. One of six dogs had a higher tumor stage on MRI compared to CT, while the remaining five agreed. Magnetic resonance imaging resulted in larger bidimensional measurements and tumor volume estimates, along with a higher likelihood of identifying meningeal enhancement when compared to CT imaging. Magnetic resonance imaging may provide integral information for tumor staging, prognosis, and treatment planning.<\/jats:p>","DOI":"10.1111\/vru.12486","type":"journal-article","created":{"date-parts":[[2017,2,24]],"date-time":"2017-02-24T08:45:01Z","timestamp":1487925901000},"page":"315-325","source":"Crossref","is-referenced-by-count":21,"title":["PROSPECTIVE COMPARISON OF TUMOR STAGING USING COMPUTED TOMOGRAPHY VERSUS MAGNETIC RESONANCE IMAGING FINDINGS IN DOGS WITH NASAL NEOPLASIA: A PILOT STUDY"],"prefix":"10.1111","volume":"58","author":[{"given":"Cassie N.","family":"Lux","sequence":"first","affiliation":[{"name":"Department of Surgical and Radiological Sciences School of Veterinary Medicine University of California\u2010Davis Davis CA 95616"},{"name":"Department of Small Animal Clinical Sciences College of Veterinary Medicine University of Tennessee 2407 River Dr Knoxville TN 37996"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William T.
