项目摘要

With major concern to its economical advantages and the easy opeating procedures, the permanent type Magnetic Resonance (MR) unit was studied for its possible use as a diagnostic imaging modality in veterinary medicine in spite of its lower magnetic intensity. Main results and conclusions which were obtained in this study are as follows ;1) Studies on desirable anesthesia, surface coils, restraint of animals, and imaging parameters have resulted in getting the clear images of most of normal tissues except the trunk of large animals.2) The diagnostic value of MR images of the brain and spinal lesions are thought to be the best of all obtained by current imaging modalities.3) MRI is thought to be excellent in the recognition of image characteristics of the nasal, paranasal and abdoominal lesions as well as X-CT.4) The most specific advantage of MRI is the possible recognition of three dimensional informaton regarding the lesional margin. This makes MRI to be a useful modality not only in the diagnosis but in the decision of the therapeutic strategy and evaluation of therapeutic effect and prognosis.5) The lesions in the tendon, the ligament and the articular cartilage, which are difficult to be diagnosed by X-ray, can be easily diagnosed with MRI by taking advantages of the possible selection of appropriate slice direction.6) These results in conjunction with the experiences in diagnostic imaging with other moalities by the members of this project team enabled us to produce the basic informations for the establishment of the systematic tree for the diagnostic imaging in veterinary medicine.From all resuts in this study, it is concluded that the diagnostic imaging procedures with permanent magnetic type MRI in small and large animals and its remarkable advantages in veterinary diagnosis have been clarified.

主要考虑到其经济优势和简便的操作程序，研究了永久型磁共振 (MR) 装置，尽管其磁场强度较低，但仍可将其用作兽医医学中的诊断成像方式。本研究获得的主要结果和结论如下：1)通过对理想的麻醉、表面线圈、动物约束和成像参数的研究，获得了除大型动物躯干外的大部分正常组织的清晰图像。 2) 大脑和脊柱病变的 MR 图像被认为是目前成像方式中最好的诊断价值。3) MRI 被认为在识别鼻腔、鼻旁和腹部病变的图像特征方面表现出色作为以及 X-CT。4) MRI 最具体的优点是可以识别有关病变边缘的三维信息。这使得MRI不仅在诊断方面成为一种有用的手段，而且在决定治疗策略以及评估治疗效果和预后方面都非常有用。5）难以诊断的肌腱、韧带和关节软骨病变通过 X 射线，可以通过选择适当的切片方向轻松地通过 MRI 进行诊断。6) 这些结果与该项目团队成员在其他领域的诊断成像经验相结合，使我们能够制作出设立基本信息兽医医学诊断成像的系统树。从本研究的所有结果来看，得出的结论是，永磁型MRI在小型和大型动物中的诊断成像程序及其在兽医诊断中的显着优势已经得到阐明。
