AB  - SUMMARY: Visualization of the optic radiations is of clinical importance for diagnosing many diseases and depicting their anatomic structures for neurosurgical interventions. In this study, we quantify proton density, T1, T2*, and susceptibility of the optic radiation fiber bundles in a series of 10 healthy control participants using strategically acquired gradient echo imaging. Furthermore, we introduce a novel means to enhance the contrast of the optic radiations using diamagnetic susceptibility weighted imaging.dSWIdiamagnetic susceptibility weighted imagingESSexternal sagittal striatumISSinternal sagittal striatumORoptic radiationSTAGEstrategically acquired gradient echoTAPtapetumHPFhigh-pass-filteredQSMquantitative susceptibility mapPDproton density
