Abstract:
Objective To analyze MRI characteristic features of TSC.Methods 13 clinically proven patients with TSC,each one had head MR scanning.Results There were mainly four findings on MRI:①Subependymal nodules,which were detected in all cases.Of them 71 lesions on T 1WI,39 lesions on T 2WI and 56 lesions on PDWI were detected;②Cortical tubers in 11 cases,114 lesions on T 2WI and PDWI,72 lesions on T 1WI were detected;③The abnormal findings of white matter,which were detected in 5 cases,10 lesions on T 2WI and PDWI,none on T 1WI were detected;④Subependymal giant cell astrocytoma,only 1 case detected.Conclusion MRI is sensitive to the changes in central neural system in TSC and is the first choice among the diagnostic imaging modalities.T 1WI is sensitive to the subependymal nodules,while T 2WI and PDWI were sensitive to the cortical tubers and abnormal findings of white matter.
