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.

目的：本研究利用MRI找出脊神經管閉合不全的位置和種類，並把它們分類。此外，亦研究了有關脊神經管閉合不全的更多相關表現，並盡可能找出MRI診斷與手術／解剖結果的相關性。
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。
結果：大多數患者（74%）年齡小於1歲。男性脊神經管閉合不全的發病率高於女性（男女比例為1.08：1）。50例中有24例屬開放式，另26例屬封閉式。腰部為最常見的部位（54.2%），其次為骶區（33.3%）。MRI診斷結果與病理組織學診斷高度一致（kappa值=0.937）。34名病人最終由病理組織學確診。
結論：脊柱MRI能為脊神經管閉合不全的病人提供一個安全、非侵入性和快捷的方法作多處病情描述，同時亦能提供高度精確的成像診斷模式。
