In this project the accuracy of a novel, rapid magnetic resonance imaging (MRI) approach to detect brain abnormalities in patients with Sturge-Weber syndrome (SWS) will be tested; this new imaging approach, that can create multiple types of MR images in about 5 minutes, without contrast administration (and sedation even in young children), can be also readily applied in other pediatric brain disorders in the future. The investigators will also study how advanced MRI, including susceptibility-weighted and diffusion tensor imaging can detect detailed signs of brain vascular and neuronal reorganization that helps improve neurological and cognitive outcome of children and young adults with SWS, who could benefit from targeted interventions in the future to minimize neurocognitive deficits in affected patients. All enrolled subjects will undergo advanced brain MRI and neurocognitive evaluation to achieve these goals.
This project will combine advanced neuroimaging with detailed neuro-psychology evaluation, performed in both children and young adults affected by Sturge-Weber syndrome, in order to address two main aims, each of them with two research hypotheses:
AIM 1. To determine the accuracy of a novel, rapid MRI approach for detection of early and advanced SWS brain abnormalities as compared to a standard MRI acquisition (current clinical standard).
Hypothesis 1.1. In young children with SWS, rapid MRI using STAGE will detect the presence and extent of brain involvement with high accuracy when compared to standard MRI.
Hypothesis 1.2. In children, adolescents, and young adults, rapid MRI using STAGE will have high accuracy to detect advanced brain vascular and parenchymal abnormalities as compared to standard MRI.
Since the detrimental neurocognitive effects of SWS brain involvement are most robust during the early disease course, early interventions, including preventive antiepileptic treatment in children with high-risk port-wine birthmark are being considered. This paradigm changing therapeutic approach would greatly benefit from safe, accurate imaging for rapid screening not requiring sedation or contrast injection. In this aim, the investigators will evaluate a recently developed, rapid, multi-echo MRI acquisition protocol (STAGE: Strategically Acquired Gradient Echo) for its ability to detect early and late SWS-related vascular and brain tissue abnormalities.
AIM 2. To assess the role of key vascular and neuronal compensatory mechanisms in neurocognitive outcome in unilateral SWS.
Hypothesis 2.1. Extensive ipsilateral deep vein collaterals will protect the SWS-affected hemisphere as indicated by relatively preserved structural brain integrity and global neurocognitive functions.
Hypothesis 2.2. In unilateral SWS, reorganized structural networks in the contralateral cerebral hemisphere will predict alterations in specific cognitive, motor, language, and executive functions.
Recent studies revealed two, potentially powerful compensatory mechanisms that may offset the effects of SWS-related brain injury in unilateral SWS: (i) expanding ipsilateral deep venous collaterals, and (ii) contralateral brain reorganization associated with preserved verbal functions at the cost of non-verbal abilities ("crowding" effect) in left-hemispheric SWS. Here the investigators will use advanced MRI techniques (such as susceptibility-weighted and diffusion tensor imaging (DTI)-based connectome analysis) to evaluate the long-term global and specific neurocognitive effects of venous vascular remodeling and structural reorganization, respectively.

Diagnostic Test: Brain magnetic resonance imaging · Behavioral: Neuro-psychology testing
Brain magnetic resonance imaging (MRI) will be done using multiple sequences to evaluate presence, type and severity of brain abnormalities in enrolled subjects.
Also known as: MRI
Participants will undergo age-appropriate neuro-psychology testing to assess motor, language and other neuro-cognitive functions potentially affected by Sturge-Weber syndrome.
Also known as: neuro-cognitive testing, neuro-psychology
Accuracy of detection of Sturge-Weber syndrome brain involvement by a novel fast magnetic resonance imaging (MRI) approach as compared to standard MRI.
Presence (score 1) vs. absence (score 0) of SWS brain abnormalities in each of 8 cerebral lobes using fast MRI compared with the same scores obtained from standard MRI, obtained in the same imaging session, as the ground truth.
Time frame: During procedure
Correlation of enlarged cerebral deep vein scores, measured by magnetic resonance imaging (MRI), with full scale IQ acquired within 1 day.
Full scale IQ (normal mean: 100, standard deviation: 15) will be determined and its correlation with enlarged deep vein scores (range: 0-12, 0 indicating no enlarged deep veins, 12 indicating the most extensive enlarged deep veins) measured by MRI calculated.
Time frame: 1 day
Correlation of diffusion tensor imaging (DTI) brain connectivity score with verbal IQ acquired within 1 day.
Verbal IQ (normal mean: 100, standard deviation: 15) will be determined by neuropsychology evaluation and correlated with DTI brain connectivity scores (range: 0-1, 0 indicating no connectivity, 1 indicating the strongest connectivity) measured by MRI.
Time frame: 1 day
Correlation of diffusion tensor imaging (DTI) brain connectivity score with non-verbal IQ acquired within 1 day.
Non-verbal IQ (normal mean: 100, standard deviation: 15) will be determined by neuropsychology evaluation and correlated with DTI brain connectivity scores (range: 0-1, 0 indicating no connectivity, 1 indicating the strongest connectivity) measured by MRI.
Time frame: 1 day
Correlation of enlarged deep vein scores determined by magnetic resonance imaging (MRI) with motor scores acquired within 1 day.
Motor scores (normal mean: 100, standard deviation: 15), determined during neuro-psychology evaluation, will be correlated with enlarged deep vein scores (range: 0-12, 0 indicating no enlarged deep veins, 12 indicating the most extensive enlarged deep veins) determined by MRI.
