Spatial resolution remains one of the major problems and goals in spinal imaging. The high spatial resolution afforded by a novel sequence, constructive interference in steady state (CISS), provides a further refinement to MRI, the modality of choice in the investigation of suspected intraspinal pathology. Both complex and subtle abnormalities are more fully elucidated using CISS. It is now used in our institution as an adjunct to conventional imaging sequences in the diagnostic evaluation of complex intraspinal pathology. The anatomical information provided by CISS is of particular value in planning surgical interventions, most notably in the management of intraaxial and extraaxial cystic abnormalities, dysraphic malformations and disturbances of cerebrospinal fluid circulation, including post-traumatic and post-surgical scarring.
空间分辨率仍然是脊柱成像中的主要问题和目标之一。一种新型序列——稳态构成性干扰序列（CISS）所提供的高空间分辨率，为磁共振成像（MRI）带来了进一步的优化，而MRI是疑似椎管内病变检查的首选方式。使用CISS能更全面地阐明复杂和细微的异常情况。目前，在我们机构中，它被用作常规成像序列的辅助手段，用于复杂椎管内病变的诊断评估。CISS提供的解剖学信息在规划手术干预方面具有特殊价值，尤其是在处理轴内和轴外囊性异常、神经管闭合不全畸形以及脑脊液循环障碍（包括创伤后和手术后瘢痕形成）时。
