Table 2.
Perfusion parameters derived from the perfusion curve.
| Perfusion Parameter | Descriptions |
|---|---|
| Arrival time (AT) | Time at the arrival of UCAs |
| Peak value (MAX) | Peak value of the perfusion curve corresponding to the flow-in UCAs |
| Time-to-peak (TTP) | Interval between AT and the time of MAX |
| Blood flow velocity (BFV) | Mean blood flow velocity within the duration of UCAs perfusion |
| Area under perfusion curve (AUC) | Area under the curve of UCAs perfusion |
