Objectives: This study aimed to characterise and categorise the site and type of spinal dysraphism as seen on magnetic resonance imaging (MRI), to study additional / associated findings in cases of spinal dysraphism, and correlate the MRI findings with surgical and / or anatomical and pathological findings wherever possible.

Methods: We prospectively studied 50 patients who presented with a clinical diagnosis of spinal dysraphism and referred to the Department of Radiodiagnosis and Imaging, Sri Guru Ram Das Institute of Medical Sciences and Research in India for MRI from January 2014 to June 2015. All patients underwent a detailed physical examination, followed by MRI.

Results: Most patients (74%) were younger than 1 year. The incidence of spinal dysraphism was higher in males (male-to-female = 1.08:1). Of the 50 patients, open spinal dysraphism was observed in 24 and closed spinal dysraphism in 26. The lumbar region was the most common site of occurrence (54.2%), followed by the sacral region (33.3%). There was an excellent agreement (kappa value = 0.937) for the evaluation of spinal dysraphism between MRI and histopathological assessments. A final histopathological diagnosis was obtained in 34 patients.

Conclusion: MRI of the spine is a safe, non-invasive, and quick method of describing the multiple findings in patients with spinal dysraphism and also serves as a highly accurate diagnostic mode of imaging.

方法:本研究報導在2014年1月至2015年6月期間印度Sri Guru Ram Das醫學研究所為曾因脊神經管閉合不全而轉介至我們機構的50名病人作前瞻性研究。所有病人均須接受詳細的身體檢查,隨後進行MRI。
