General - Tractography Models in Neurosurgery: DTI vs. CSD Comparison

This episode examines a retrospective comparative analysis of diffusion tensor imaging (DTI) and constrained spherical deconvolution (CSD) tractography models for neurosurgical navigation. Published in Neurologia medico-chirurgica in 2026, this abstract-based discussion highlights how CSD, which accounts for multiple fiber orientations, consistently reconstructs larger white matter tract volumes compared to the traditional DTI model. Key findings show CSD yielded significantly greater volumes across five major white matter tracts in 37 patients, with visual assessments also favoring CSD reconstructions. The implications for enhanced preoperative planning and risk assessment in neurosurgical practice are discussed.
