Thoracolumbar radiography revealed an abnormal radiopacity suggestive of a mass at T11. Two 3.5-cm-long osseous core biopsy specimens of the mass were obtained by MRI guidance. Histologic appearance of the specimens was consistent with osteosarcoma.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>TREATMENT AND OUTCOME<\/jats:bold>\n                    The owners of the dog declined further treatment owing to a poor prognosis. The dog was euthanized within 12 months after diagnosis because of a declining quality of life.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>CLINICAL RELEVANCE<\/jats:bold>\n                    The acquisition of biopsy specimens by MRI guidance is an emerging technique in veterinary medicine. As evidenced by the dog of this report, MRI-guided biopsy can be used to safely obtain diagnostic biopsy specimens from tissues at anatomic locations that are difficult to access. This technique can potentially be used to facilitate early diagnosis and treatment of disease, which could improve patient outcome. The MRI guidance technique described may also be useful for local administration of chemotherapeutics or radiofrequency ablation or cryoablation of various neoplasms of the vertebral column.\n                  <\/jats:p>","DOI":"10.2460\/javma.250.7.779","type":"journal-article","created":{"date-parts":[[2017,3,17]],"date-time":"2017-03-17T14:31:17Z","timestamp":1489761077000},"page":"779-784","source":"Crossref","is-referenced-by-count":6,"title":["Use of magnetic resonance imaging\u2013guided biopsy of a vertebral body mass to diagnose osteosarcoma in a Rottweiler"],"prefix":"10.2460","volume":"250","author":[{"given":"Rebecca A.","family":"Krimins","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Fritz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Larry A.","family":"Gainsburg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick R.","family":"Gavin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth A.","family":"Ihms","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David L.","family":"Huso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dara L.","family":"Kraitchman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"Top Magn Reson Imaging","doi-asserted-by":"publisher","first-page":"135","DOI":"10.1097\/RMR.0b013e3182805f7b","article-title":"Magnetic resonance imaging-guided biopsy of musculoskeletal lesions using open low-field systems","volume":"22","author":"Li","year":"2011"},{"key":"ref2","series-title":"Cardiovasc Intervent Radiol","doi-asserted-by":"publisher","first-page":"146","DOI":"10.1007\/s00270-011-0119-9","article-title":"Magnetic resonance imaging-guided osseous biopsy in children with chronic recurrent multifocal osteomyelitis","volume":"35","author":"Fritz","year":"2012"},{"key":"ref3","series-title":"Invest Radiol","doi-asserted-by":"publisher","first-page":"464","DOI":"10.1097\/RLI.0b013e31827b9f86","article-title":"Augmented reality visualization using image overlay technology for MR-guided interventions: cadaveric bone biopsy at 1.5 T","volume":"48","author":"Fritz","year":"2013"},{"key":"ref4","series-title":"J Magn Reson Imaging","doi-asserted-by":"publisher","first-page":"1740","DOI":"10.1002\/jmri.24924","article-title":"MRI-guided percutaneous transpedicular biopsy of thoracic and lumbar spine using a 0.23T scanner with optical instrument tracking","volume":"42","author":"Liu","year":"2015"},{"key":"ref5","series-title":"J Magn Reson Imaging","doi-asserted-by":"publisher","first-page":"311","DOI":"10.1002\/jmri.21270","article-title":"MR-guided biopsy: a review of current techniques and applications","volume":"27","author":"Weiss","year":"2008"},{"key":"ref6","series-title":"Adv Exp Med Biol","doi-asserted-by":"publisher","first-page":"237","DOI":"10.1007\/978-3-319-04843-7_13","article-title":"Using canine osteosarcoma as a model to assess efficacy of novel therapies: can old dogs teach us new tricks?","volume":"804","author":"Rodriguez","year":"2014"},{"key":"ref7","series-title":"Vet Res Commun","doi-asserted-by":"publisher","first-page":"61","DOI":"10.1007\/s11259-014-9623-0","article-title":"What do we know about canine osteosarcoma treatment?
