回顾了40只经组织学证实的原发性和继发性颅内肿瘤犬的磁共振（MR）图像。41例肿瘤通过MRI诊断，其中37例诊断为肿瘤性病变。根据MRI特征，24/27例（89%）原发性脑肿瘤和13/14例（92%）继发性脑肿瘤的肿瘤性和非肿瘤性病变之间的区分是可能的。基于MRI特征的肿瘤类型诊断在19/27（70%）原发性肿瘤和13/14继发性肿瘤中是正确的。这项研究的结果表明，MRI是一个很好的诊断成像方式来检测肿瘤病变和诊断肿瘤类型的狗。然而，由于一些肿瘤显示不明确的MRI特征，该技术在检测某些颅内肿瘤和预测肿瘤类型方面存在局限性。(C)2009爱思唯尔有限公司保留所有权利。
Magnetic resonance (MR) images of 40 dogs with histologically confirmed primary and secondary intracranial tumours were reviewed. Forty-one tumours were diagnosed by means of MR imaging (MRI).MRI findings allowed diagnosis of a neoplastic lesion in 37/41 cases. Based on MRI features, differentiation between neoplastic and non-neoplastic lesions was possible in 24/27 (89%) primary brain tumours and in 13/14 (92%) secondary brain tumours. Diagnosis of tumour type based on MRI features was correct in 19/27 (70%) primary tumours and in 13/14 secondary tumours. The results of this study show that MRI is a good diagnostic imaging modality to detect neoplastic lesions and to diagnose tumour type in dogs. However, as some neoplasms show equivocal MRI features the technique has limitations in the detection of some intracranial tumours and in predicting tumour type. (C) 2009 Elsevier Ltd.
