The purpose of this prospective study was to describe magnetic resonance imaging (MRI) and computed tomographic (CT) features of the normal nasal cycle in a group of dogs. Five dogs were recruited that met the following criteria: 8 to 15 months old, nonbrachiocephalic breed, no clinical signs or history of nasal disease, and undergoing anesthesia for problems unrelated to the nasal cavity. Nasal MRI (<jats:italic>n<\/jats:italic> = 5) and CT scans (pre\u2010 and postcontrast, <jats:italic>n<\/jats:italic> = 5) were acquired. Images were evaluated subjectively by two board\u2010certified radiologists and objectively by a diagnostic imaging intern using regions of interest placed on each side of the nasal cavity. Findings were compared using Cohen's kappa coefficient and Students <jats:italic>t<\/jats:italic>\u2010test on log\u2010transformed data. All dogs showed diffuse unilateral mucosal thickening of the rostral part of the nasal cavity in both MRI and CT studies. This mucosal thickening shifted sides between examinations in three dogs. Changes appeared most marked on T2\u2010weighted scans. No asymmetric mucosal changes were seen in the mucosa of the ethmoturbinates, vomer\u2013nasal septum, hard palate or the frontal sinuses in any patient on MRI or CT. Computed tomographic contrast enhancement of the thickened mucosa was not statistically significant (<jats:italic>P<\/jats:italic>\u2010value &lt; 0.08). In conclusion, the normal nasal cycle may cause asymmetrical mucosal changes in the rostral part of the nasal cavity that mimic MRI and CT characteristics previously reported for inflammatory disease in dogs.<\/jats:p>","DOI":"10.1111\/vru.12115","type":"journal-article","created":{"date-parts":[[2013,10,17]],"date-time":"2013-10-17T08:46:47Z","timestamp":1381999607000},"page":"159-165","source":"Crossref","is-referenced-by-count":15,"title":["ASYMMETRIC NASAL MUCOSAL THICKENING IN HEALTHY DOGS CONSISTENT WITH THE NASAL CYCLE AS DEMONSTRATED BY MRI AND CT"],"prefix":"10.1111","volume":"55","author":[{"given":"Lisa","family":"Friling","sequence":"first","affiliation":[{"name":"Department of Diagnostic Imaging Regional Animal Hospital Bagarmossen  S\u2010128 48 Bagarmossen Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helena T.","family":"Nyman","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Imaging Regional Animal Hospital Bagarmossen  S\u2010128 48 Bagarmossen Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria","family":"Johnson","sequence":"additional","affiliation":[{"name":"Vet CT Specialists Ltd  Cambridge CB4 0WS"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,10,17]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"28","article-title":"The human nasal cycle","volume":"52","author":"Hasegawa M","year":"1977","journal-title":"Mayo Clin Proc"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000441-192708000-00008"},{"key":"e_1_2_6_4_1","first-page":"403","article-title":"Some practical considerations of the physiology of the upper respiratory tract","volume":"13","author":"Lillie HI","year":"1923","journal-title":"J lowa Med Soc"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016485309132516"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaci.2006.09.013"},{"key":"e_1_2_6_7_1","first-page":"101","article-title":"Die exacte Messung der Luftdurchgangigkeit der Nase","volume":"3","author":"Kayser R","year":"1895","journal-title":"Arch Laryngol"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016485209120341"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198811000-00019"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016487809124769"},{"key":"e_1_2_6_11_1","first-page":"145","article-title":"A reconsideration of the relation of the mechanics of nasal air\u2010flow to the function of the nose in respiration","volume":"10","author":"Williams HL","year":"1972","journal-title":"Rhinology"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/9780813810324.ch6"},{"key":"e_1_2_6_13_1","first-page":"25","article-title":"Nasal swell\u2010bodies and cyclic changes in the air passages of the rat and rabbit nose","volume":"110","author":"Bojsen\u2010Moller F","year":"1971","journal-title":"J Anat"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016487809121472"},{"key":"e_1_2_6_15_1","first-page":"127","article-title":"The nasal cycle in swine","volume":"19","author":"Campbell WM","year":"1981","journal-title":"Rhinology"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016488109133272"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198709000-00024"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.2003.64.1093"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1984.00800280042013"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100054980"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016487709123985"},{"key":"e_1_2_6_22_1","first-page":"99","article-title":"On a nasal cycle","volume":"6","author":"Keuning J","year":"1968","journal-title":"Int Rhinol"},{"key":"e_1_2_6_23_1","first-page":"24","article-title":"The \u201cnasal cycle\u201d in infants","volume":"84","author":"Fox GP","year":"1991","journal-title":"Ir Med J"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.96.09020371"},{"key":"e_1_2_6_25_1","first-page":"69","article-title":"Reciprocal changes in nasal resistance in response to changes in posture","volume":"36","author":"Babatola FDO","year":"1998","journal-title":"Rhinology"},{"key":"e_1_2_6_26_1","first-page":"95","volume-title":"Veterinary computed tomography","author":"Saunders J","year":"2011"},{"key":"e_1_2_6_27_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199301000-00002"}],"container-title":["Veterinary Radiology &amp;
