Brief Summary

The goal of this work is to use advanced magnetic resonance imaging (MRI) methods to assess brain blood flow and vascular function in adults with moyamoya disease (MMD). MMD is a condition characterized by narrowing or obstruction of major arteries in the brain and people with MMD have a high risk of stroke. Study participants will be enrolled from Vanderbilt University Medical Center and Johns Hopkins Hospital and will undergo up to two MRI scans where measurements of cerebrovascular reserve are performed using inhaled room air mixed with 5% carbon dioxide. Scans will be performed before and after surgeries to treat MMD, all surgeries are clinically indicated and are not research procedures. To further understand how surgeries impact brain health, we will also perform neurological exams and cognitive testing at approximately the same time as the imaging scans. The overall goal is to incorporate advanced imaging and cognitive assessments to understand how surgeries improve brain health in these patients, and furthermore, to use this information to develop improved screening tools for stroke risk and decisions about surgery.

Outcome Measures

Primary Outcomes (1)

  • Revascularization success

    The outcome measure will be the number of patients with successful surgical revascularization.

    6 years

Secondary Outcomes (1)

  • Infarct development

    6 years

Study Arms (2)

Moyamoya

Adults diagnosed with Moyamoya who are being considered for revascularization surgery.

Other: BOLD MRI

Control

Healthy adults who will under go a BOLD MRI for research purposes.

Other: BOLD MRI

Interventions

The study will utilize the MRI diagnostic reactivity test to evaluate cerebrovascular reactivity in patients with moyamoya and healthy controls. All participants (patients and controls) receive the same diagnostic scan, and there is no cross-over, factorial, or sequential nature to the study.

ControlMoyamoya
