目的：探讨ＭＲ脊髓成像ＣＩＳＳ－ ３Ｄ技术的应用价值。方法：对４５ 例（男２７例，女１８例）病人用Ｓｉｅｍ ｅｎｓ Ｖｉｓｉｏｎ １．５ Ｔ磁共振仪用ＣＩＳＳ－ ３Ｄ序列进行脊髓成像术检查，所得原始图像用曲面重建处理。结果：所有病例均获得高质量、高对比的脊髓腔图像，其中阳性３３例，包括脊髓损伤５例，椎管内肿瘤１２例，脊髓先天异常４ 例，脊椎骨病变３例，阴性１２例。结论：ＣＩＳＳ－ ３Ｄ序列ＭＲ脊髓成像是可靠的，减少了对ＭＲ脊髓增强检查的需要。
Objective: To explore the value of CISS-3D in MR spinal imaging. Methods: Spinal cord imaging was performed on 45 patients (27 males and 18 females) by CISS-3D with Siem ens Vision 1.5 T magnetic resonance imaging. The original images were obtained by surface reconstruction. Results: High quality and high contrast images of the spinal cord were obtained in all the cases. Among them, 33 cases were positive, including 5 cases of spinal cord injury, 12 cases of spinal canal tumor, 4 cases of spinal cord congenital anomalies, 3 cases of spinal bone lesions and 12 cases negative. CONCLUSIONS: CISS-3D serial MR spinal imaging is reliable and reduces the need for MR spinal cord enhancement.
