What You Need to Know Before You Apply

What is the purpose of this trial?

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.

Do I need to stop my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What safety data exists for neuroimaging in Sturge-Weber Syndrome?

The research provided does not directly address safety data for neuroimaging techniques like MRI, DWMRI, or other related assessments in Sturge-Weber Syndrome. The studies focus on the diagnostic capabilities and effectiveness of these imaging techniques in detecting brain abnormalities associated with the syndrome. However, MRI and its variants are generally considered safe, non-invasive diagnostic tools commonly used in clinical settings. ^{1 2 3 4 5}

Is Brain Magnetic Resonance Imaging (MRI) a promising treatment for Sturge-Weber Syndrome?

Yes, Brain MRI is a promising treatment for Sturge-Weber Syndrome. It helps doctors see brain abnormalities and assess the extent of the disease. MRI can detect issues in the brain that might not be visible with other methods, which is important for understanding and managing the condition. ^{2 3 5 6 7}

What data supports the idea that Neuroimaging for Sturge-Weber Syndrome is an effective treatment?

The available research shows that neuroimaging, specifically MRI, is effective in detecting early signs of Sturge-Weber Syndrome in children who have a facial birthmark. This early detection can help in managing the condition before symptoms appear. Additionally, MRI can identify brain areas that might be affected, which is crucial for planning treatment. While the studies don't directly compare neuroimaging to other treatments, they highlight its importance in diagnosing and understanding the extent of the condition, which is a key step in effective management. ^{1 3 6 8 9}

Early magnetic resonance imaging (MRI) can accurately diagnose Sturge-Weber syndrome (SWS) in asymptomatic infants with a facial port-wine birthmark, achieving a sensitivity of 100% and specificity of 94% based on the presence of specific imaging markers.

Identifying SWS early through MRI allows for timely neuroprotective interventions, potentially improving outcomes for affected infants.

Magnetic Resonance Spectroscopic Imaging (MRSI) is more effective than conventional MRI in detecting frontal lobe abnormalities in children with Sturge-Weber syndrome (SWS), revealing issues even when frontal lobes appear normal on standard scans.

Lower levels of N-acetyl-aspartate (NAA) in the frontal lobe are strongly linked to earlier seizure onset and poorer motor function, making MRSI a valuable tool for predicting motor outcomes in these patients.

Magnetic resonance angiography (MRA) is effective in identifying vascular anomalies associated with Sturge-Weber syndrome, as demonstrated in a study of four pediatric patients.

Venous MRA specifically revealed significant findings such as reduced flow in the transverse sinuses and jugular veins, which can aid in the diagnosis and understanding of cerebral vascular changes in affected individuals.

Magnetic resonance perfusion imaging is an effective tool for detecting perfusion abnormalities in pediatric patients with Sturge-Weber syndrome, as demonstrated in a study of 7 children.

The study found that perfusion abnormalities often correlated with meningeal enhancement and were consistently located near developmental venous anomalies, highlighting the utility of this imaging technique in assessing the disease's extent.

MRI scans of two infants with Sturge-Weber syndrome revealed accelerated myelination in the affected hemisphere, particularly visible on T1-weighted images.

The observed changes in myelination and brain hydration may be linked to cerebral ischemia caused by the presence of leptomeningeal angioma, suggesting a potential mechanism for these MRI findings.

Infratentorial involvement in children with Sturge-Weber syndrome (SWS) is more common than previously recognized, occurring in 40% of the studied patients, with lesions including cerebellar atrophy and developmental venous anomalies.

Analysis of apparent diffusion coefficient (ADC) values in normal appearing white matter (NAWM) indicates impaired white matter maturation, which may contribute to neurocognitive deficits in SWS patients, suggesting that ADC analysis could be a useful biomarker for assessing tissue injury and guiding treatment.

Susceptibility weighted imaging (SWI) was found to be more effective than standard T1 weighted postgadolinium contrast MRI (T1-Gd) in identifying key abnormalities in children with Sturge-Weber Syndrome, including enlarged transmedullary veins and cortical gyriform abnormalities, based on a study of 12 children.

While SWI excelled in detecting certain vascular and cortical changes, T1-Gd was better at identifying enlarged choroid plexus and leptomeningeal abnormalities, suggesting that both imaging techniques provide complementary information and should be used together in clinical assessments.

In a study of 55 patients with Sturge-Weber syndrome (SWS) over 40 years, epilepsy was the most common and severe feature, affecting 85.5% of patients, with only 42.5% achieving complete seizure control, often requiring surgical intervention.

The study highlighted that while early surgical treatment can help control seizures, other neurological issues like hemiparesis and intellectual deficits showed less improvement, indicating a need for comprehensive care to enhance the quality of life for SWS patients.

In a study of seven patients with Sturge-Weber syndrome, contrast-enhanced MR imaging using Gd-DTPA was crucial for diagnosing the condition, revealing significant abnormalities that were not visible on unenhanced MR or CT scans.

The most consistent finding across patients was pial angiomatosis, which, along with adjacent cerebral atrophy, is considered the key radiographic feature for diagnosing Sturge-Weber syndrome.
