全景矩阵成像技术MR全脊柱成像的临床应用

目的：研究全号矩阵成像（Total Image Matrix）技术磁共振全脊柱成像在诊断脊柱及脊髓病变的临床应用价值。方法：采用西门子Avanto 1．5T超导磁共振成像系统，Tim线圈、自动移床及无缝拼接技术．对75例可疑脊柱及脊髓病变者行全脊柱成像，并对病变局部行高分辨力成像。结果：75例均清晰、直观、完整的显示椎管内全段脊髓、全部脊椎及周围韧带的连续全脊柱MR图像，75例中MRI全脊柱成像显示15例正常，41例脊柱病变，19例脊髓病变。结论：全景矩阵成像技术MR全脊柱成像明显缩短了扫描时间。图像质量好，定位、定性准确性高，解决了大范围、高分辨力的脊柱成像难题，对脊枉、脊髓多发性、弥漫性病变的诊断有较大价值。

Clinical Applications of MR Whole Spine Imaging with Total Imaging Matrix

Objective To study the values of MR whole spine imaging with TIM（Total Imaging Matrix） technique in diagnosing spine and spinal cord diseases.Methods Eighty-five patients who were suspected having spine diseases underwent whole spine MR. High resolution MR is performed when a local lesion was found on a Avanto 1.5T MR system（Siemens Company） by using different TIM in coils combination with automatic moving table and no-gap composing techniques. Results All 75 cases can be obtained clear images of total spine and spinal cord. In the all of 75 cases whole spine MR, the results show that normal in 15 cases, vertebral diseases in 41 cases, and spinal cord diseases in 19 cases. Conclusion The MR whole spine imaging with total imaging matrix has shorter scanning time and better image quality, position and nature of high accuracy, resolved the controversy of imaging covering and resolution. It can be improved the accuracy in diagnosing spine and spinal cord diseases.
