[Abstract] Objective: To evaluate the perfusion status of involved white matter in Sturge-Weber syndrome (SWS) using dynamical susceptibility contrasted perfusion imaging (DSC-PI), and then to compare the perfusion data and seizure variables, including age of first seizure, seizure frequency (score of seizure frequency, SSF) and duration of epilepsy, for reasonable explaining the hemodynamics and seizure variables in SWS.Materials and Methods: 14 patients (8 girls and 6 boys; age range, 0.8-10.0 years; median age, 4.0 years) with Sturge-Weber syndrome were recruited and performed MRI examination. All patients with unilateral lesions were located in one side of the cerebral hemispheres. MR protocols included axial and sagittal T1-weighted, axial fast spin-echo (FSE) T2-weighted, DSC-PI and contrasted T1-weighted. All raw data of DSC-PI were processed through the SPIN software (signal process in neuroimage). After determining the location and realm of SWS lesions, the CBF, CBV and MTT value of the affected and contralateral white matter were measured, and then the ratio of perfusion data, including CBFr, CBVr and MTTr were calculated. According to the CBFr values, all cases were divided into hyperperfusion group (HP) and hypoperfusion group (LP). The comparison of CBF, CBV and MTT values between the affected and contralateral hemispheres was tested by Mann-Whitney U analysis. The correlations of all perfusion data and seizure variables (age of first seizure, SSF and duration of epilepsy) were analyzed by Spearman correlation analysis.Results: In all, nine cases belonged to the LP group according to the significantly decreased CBF and CBV in the affected white matter compared to those in the contralateral’s (CBFr=-0.37±0.24, CBVr=-0.22±0.25, P<0.01), and the other 5 cases were in the HP group based on the significantly increased CBF and CBV of affected white matter (CBFr=0.31±0.05; CBVr=0.40±0.17, P<0.01). The age and SSF of LP group were slightly higher than HP group (age were 63.80 months & 48.83 months; SSF were 2.50 & 1.33), but no significant difference was present respectively (P=0.36, 0.12). Longer duration of epilepsy was related to lower CBF (more negative CBFr, r=-0.58, P<0.05) and low CBV (r=-0.55, P<0.05) on the affected side. Lower perfusion was associated with more frequent seizures (CBFr: r=-0.56, CBVr: r=-0.63, P<0.05).Conclusions: The perfusion of affected white matter in Sturge-Weber syndrome did not decrease continuously as illustrated by previous studies, whiles the relatively hyperperfusion was considered as a common phenomena. There are relationships between brain perfusion status and seizure severity in SWS.
