Fifty cases with histological diagnosis of nasal tumour were found. The appearance and extent of the nasal tumour as well as the involvement of adjacent anatomic structures were examined against a checklist.<\/jats:bold>\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      R\n                      <jats:sc>esults<\/jats:sc>\n                      :\n                    <\/jats:bold>\n                    <jats:bold>The most common magnetic resonance imaging findings were as follows. (1) Soft tissue mass replacing the destroyed nasal conchae and\/or ethmoturbinates (98 per cent of cases). (2) Nasal septum destruction (68 per cent of cases). (3) Retained secretions with or without mass caudally in frontal sinuses (62 per cent of cases). (4) Nasal\/frontal bone destruction (52 per cent of cases). Low\u2010field magnetic resonance imaging allowed differentiation of tumour tissue from retained secretions or necrotic tissue. Magnetic resonance imaging was invaluable in assessing the extension of the tumour into the maxillary recesses, caudal recesses, nasopharynx, adjacent bones and cranial cavity. The tumour often extended caudally into the frontal sinuses, nasopharynx and perhaps most importantly into the caudal recesses. Tumour extension into the cranial cavity was not common (16 per cent), and only three of these cases showed neurological signs. However, 54 per cent of cases showed focal meningeal (dural) hyperintensity, although the significance of this is unclear. A significant difference (P&lt;0\u00b705) in tumour signal intensity between the sarcomas and carcinomas was found.<\/jats:bold>\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      C\n                      <jats:sc>linical<\/jats:sc>\n                      S\n                      <jats:sc>ignificance<\/jats:sc>\n                      :\n                    <\/jats:bold>\n                    <jats:bold>The use of a low\u2010field magnetic resonance imaging technique is excellent for the diagnosis and determination of extent of sinonasal tumours.<\/jats:bold>\n                  <\/jats:p>","DOI":"10.1111\/j.1748-5827.2007.00512.x","type":"journal-article","created":{"date-parts":[[2008,3,27]],"date-time":"2008-03-27T02:37:28Z","timestamp":1206585448000},"page":"233-243","source":"Crossref","is-referenced-by-count":31,"title":["Retrospective review of 50 canine nasal tumours evaluated by low\u2010field magnetic resonance imaging"],"prefix":"10.1111","volume":"49","author":[{"given":"A.","family":"Avner","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
