Introduction: Spinal tumors typically manifest early with signs of compression and/or invasion, highlighting the critical importance of timely management to prevent irreversible neurological deficits. The aim of this study was to assess the diagnostic efficacy of radiology in accurately establishing a preliminary working diagnosis for various types of spine tumors. Materials and Methods: This prospective study examined patients who underwent surgical resection and had histopathology samples collected, irrespective of age or gender. A comprehensive MRI examination from all perspectives, along with contrast-enhanced images, was conducted. Inclusion criteria encompassed patients of all age groups and genders who had surgery with tissue sample collection for histopathological diagnoses, as well as a complete MRI study including all views and contrast-enhanced images for preliminary diagnosis. Results: According to senior radiologists' assessments, the most common tumor position was intradural-extramedullary relative to the dura, followed by intramedullary. Despite 20 cases being misdiagnosed, the overall diagnostic accuracy of MRI remained high at 69.2%. Conclusion: MRI exhibits superior diagnostic accuracy in identifying meningiomas compared to nerve sheath tumors. Additionally, it demonstrates good predictive accuracy for intramedullary lesions such as ependymomas.
