BrainStat
BrainStat is an MR Time Course imaging READY View protocol that provides accurate spatial resolution for brain tissue viability given by hemodynamic parameters: BV, BF, TTP, MTT (SVD) BAT, Tmax. These hemodynamic parameters can provide unique information on tissue changes and improve delineation of vascular-deficient or vascular-rich regions in normal and abnormal anatomy.
There are two versions of BrainStat:
- BrainStat GVF (Gamma Variate Fit ) generates processed maps based on a Gamma Variate Fit.
- BrainStat AIF (Artery Input Function) generates processed maps that are based on Artery Input Functions. There are three modes to detect Artery pixels.
- Auto Vessel Selection: Arteries are automatically detected and displayed (default option).
- Semi Auto Vessel Selection: You place an ROI in the region of interest for the detection of arteries.
- Manual Vessel Selection: You define one artery.
BrainStat AIF measurement units
The BrainStat AIF functional maps have the following units of measurement.
| Maps | Units |
|---|---|
| AIF- Blood Flow (Relative) | ml/100g/m |
| AIF- Blood Volume (Relative) | ml/100g |
| AIF-Time To Peak | seconds |
| AIF-Mean Transit Time | seconds |
| AIF-Bolus Arrival Time | seconds |
| AIF-Tmax | seconds |
| AIF-Mean Transit Time (SVD) | seconds |
