Interpreting CT Scan Results
Looking at CT scan images is very important. Finding areas with less blood flow is crucial in moyamoya disease. It shows where the blood flow is low in the brain. Moyamoya Disease Brain Scan Results
CT angiography gives more detailed views of blood vessels. This helps doctors see where the blood flow is blocked or narrowed.
| CT Scan Function | Purpose |
|---|---|
| Computed Tomography | Rapid imaging to assess urgent conditions such as intracranial hemorrhage |
| Ischemic Changes Detection | Identifying areas with reduced blood flow |
| CT Angiography | Visualizing blood vessels to identify blockages or narrowing |
Key Findings in Moyamoya Disease Brain Scan
Brain scans show special signs that help doctors diagnose and treat Moyamoya disease. The diagnostic criteria look for certain brain scan features.
A key sign is steno-occlusive changes. These mean the arteries in the brain get narrow or blocked, cutting off blood flow. This often happens in the main arteries and their branches.
Because of these changes, the brain tries to make new blood paths. These paths look like “puff of smoke” on scans. Seeing these paths is key to diagnosing the disease. Cerebral angiography shows these paths best, revealing the brain’s effort to compensate.
| Feature | Description |
|---|---|
| Steno-Occlusive Changes | Narrowing and blockage of key cerebral arteries |
| Collateral Network Visualization | Development of small compensatory blood vessels, seen as “puff of smoke” |
These signs are vital for diagnosing Moyamoya disease. They show why detailed brain scans are crucial. Doctors use these scans to plan treatments and track the disease’s progress.
Spotting these brain scan features early helps with quick diagnosis. It also helps doctors make good treatment plans. This leads to better care for patients, whether through surgery or other treatments.
Preparing for Your Brain Scan
