Degenerations of the spinal disc especially in the lumbar region are the most frequent degenerative diseases in orthopedics. As diagnostic proceedings to discover disc herniation myelography and computerized tomography have been proven to be very usefull. Each of those methods show a high sensitivity and accuracy. Computerized tomography seems to be the first procedure because of the lac of any risk. Myelography has been reserved for the second approach, if there is any doupt in diagnosis. This paper will especially discuss advantages and disadvantages of MRI-tomography for the diagnosis of disc herniation. In MRI-tomography we have no radiation, there is no risk for the patient and we have the possibility of slices in different orientations with the sagittal orientation having priority in diagnosis of disc herniation. A more pronounced contrast in MRI relatively to the computerized tomography with nearly the same spatial resolution is an other important fact in favour for MRI. The value of MRI diagnosis of the spine depends however mainly on the use of special surface coils and on the use of high magnetic fields which provides a good signal to noise relation and which would permit us to use a thin-slice technique.
椎间盘退变，尤其是腰椎间盘退变，是骨科最常见的退行性疾病。作为发现椎间盘突出症的诊断方法，脊髓造影和计算机断层扫描已被证明非常有用。这些方法中的每一种都显示出高灵敏度和准确性。由于没有任何风险，计算机断层扫描似乎是首选方法。如果诊断有任何疑问，脊髓造影则留作第二种方法。本文将特别讨论磁共振成像断层扫描在诊断椎间盘突出症方面的优缺点。在磁共振成像断层扫描中，我们没有辐射，对患者没有风险，并且我们有可能以不同方向切片，矢状面方向在诊断椎间盘突出症时具有优先性。与具有几乎相同空间分辨率的计算机断层扫描相比，磁共振成像中更明显的对比度是有利于磁共振成像的另一个重要事实。然而，脊柱磁共振成像诊断的价值主要取决于特殊表面线圈的使用以及高磁场的使用，高磁场可提供良好的信噪比，并允许我们使用薄层技术。
