| Changes in collateral networks | Checks if treatments work and if the disease is stable |
| New ischemic lesions | Tracks new stroke events |
Advanced MRI Techniques for Moyamoya Disease
Advanced MRI techniques are key in diagnosing and managing Moyamoya disease. They give detailed views of how the disease affects the brain’s structure and function.
Diffusion Tensor Imaging (DTI)
DTI is a top-notch method that shows the health of white matter tracts in the brain. It’s vital for seeing how Moyamoya disease changes the brain’s connections. Doctors can spot small changes in white matter that regular MRI can’t.
Magnetic Resonance Angiography (MRA)
MRA is a safe way to see blood vessels without using contrast agents. It gives clear images of narrowed or blocked arteries, which is key for Moyamoya disease.
Functional MRI (fMRI)
fMRI is crucial for seeing how Moyamoyo affects brain function. It tracks brain activity by watching blood flow changes. This helps doctors understand cognitive and neurological issues from Moyamoya. Studies in the Brain Topography journal show how fMRI helps plan treatments for Moyamoya patients.
| Technique | Purpose | Benefits |
|---|---|---|
| DTI Imaging | White matter integrity | Detects subtle connectivity changes |
| MRA Technique | Blood vessel imaging | High-resolution, non-invasive |
| fMRI in Moyamoya | Brain function assessment | Evaluates cognitive and neurological impairments |

Moyamoya Disease MRI: Diagnostic Imaging Insights Getting ready for an MRI for Moyamoya disease can feel stressful. But, knowing what to expect can help ease your worries. This part will give you key info on MRI prep, patient guidelines, and safety tips for a smooth test.
What Patients Can Expect
When you’re getting ready for a Moyamoya MRI, it’s important to know about the scan’s length, what you might feel, and if you’ll need contrast. Here’s what you should expect:
- Duration: The MRI scan usually takes 45 minutes to an hour. This depends on how complex your case is.
- Sensations: You might hear loud noises during the scan. These come from the machine working. You’ll get earplugs or headphones to help block the sound.
- Use of Contrast Material: Sometimes, a special dye is given to make blood vessels show up better. This means you’ll get an extra injection before the scan.
Pre-MRI Guidelines and Precautions
Getting ready for your MRI is important for getting clear images and keeping you safe. Here are some key tips and safety steps:
- Medical History: Tell the MRI team about your medical history, past surgeries, allergies, and what medicines you’re on.
