Three-dimensional (3D) magnetic resonance imaging of the spine is now clinically feasible due to technological advancements. Its advantages over two-dimensional imaging include higher in-plane spatial resolution and the ability for reformation in any plane that enables time savings in image acquisition and aids more accurate interpretation. Multispectral 3D techniques for imaging around metal are sometimes useful for evaluating anatomy adjacent to spinal fixation hardware. 3D gradient-recalled echo sequences, including ultrashort or zero time to echo sequences, can provide osseous detail similar to conventional computed tomography.
由于技术的进步，现在脊柱的三维（3D）磁共振成像在临床上已经成为可能。与二维成像相比，它具有更高的平面空间分辨率，并且能够在任何平面进行重组，从而节省图像采集时间，并有助于更准确的解释。用于金属周围成像的多谱 3D 技术有时可用于评估脊柱固定硬件附近的解剖结构。3D 梯度回波序列，包括超短或零回波时间序列，可提供类似于传统计算机断层扫描的骨性细节。
