Abstract： Intraspinal tumours encompass a diverse group of pathological types and often cause varying extent of neurological deficits.Precisepreoperativeevaluationiscrucial forsurgicalplanningandprognosticassessment. Conventional magnetic resonance imaging（MRI），with itsexcellntabilityto depict anatomical structures，remains theprimaryimaging modalityfordiagnosing intraspinaltumours，yetitislimitedincharacterizing tumourpathology and assessing spinal cord tisse damage.In recent years，quantitative magnetic resonance imaging（qMRI） techniques haveemergedaspromising toolsforcharacterizingmicrostructural，metabolic，andhaemodynamictissue properties，offering new directions for theprecisediagnosisandtreatment of intraspinal tumours.Thisreview systematicallysummarizes quantitative parameters derived from conventional MRI as wellas recent advances in qMRI techniquesforevaluating intraspinaltumours，withspecialfocusontheirclinicalapplicability，technical challenges， and future development prospects.
