title: [Diagnostic value of CT and MRI for the diagnosis of coronoid pathology in the dog].
abstract: OBJECTIVE
  The diagnostic value of CT and MRI regarding the diagnosis of coronoid pathology in the dog.
  
  
  METHODS
  Computed tomography (CT) and magnetic resonance imaging (MRI) of the elbow joint were performed in dogs with clinical and radiological signs of coronoid pathology. Afterwards, all dogs underwent arthroscopic surgery. For the computed tomographic examination, a 16-slice-CT-scanner spiral-CT (Philips Brilliance 16) was used. The MRI-examination was performed with a 1-Tesla superconducting magnet (Phillips Intera 1.0). T1 and T2 weighted images with different sequences were acquired.
  
  
  RESULTS
  In total, 44 elbow joints from 44 patients (total of 12 breeds, including mixed breeds) were examined. The most represented breeds were Labrador Retrievers (38.6%, n=17), mixed breed dogs (22.7%, n=10) and Golden Retrievers (11.4%, n=5) were represented most. The age of the 30 male dogs (68%) and 14 female dogs (32%) ranged from 6 to 117 months (mean 2.25 years). Using CT, the following results could be evaluated: a) fissure at the level of the Processus coronoideus medialis ulnae (PCM) in 66% (n=29); b) fragments at the level of the PCM in 55% (n=24); c) deformation at the level of the PCM in all 44 joints; d) increased opacity at the level of the base of the PCM in all 44 joints; e) heterogenous opacity at the apex of the PCM in 91% (n=41). With MRI, the following results could be evaluated: a) fissure at the level of the PCM in 59% (n=26); b) fragments at the level of the PCM in 57% (n=25); c) deformation at the level of the PCM in 86% (n=38); d) increased opacity at the level of the base of the PCM, thus making assessment impossible; e) heterogenous opacity at the apex of the PCM, thus making assessment impossible.
  
  
  CONCLUSIONS
  Both diganostic imaging modalities are appropriate for evaluating coronoid pathology in the dog.
