Overview of the perfusion categories of the regions of interest (ROIs) in the ischemic hemisphere as measured by CTP/MRP and UPI.
| Regions of interest | CTP/ MRP (n) | UPI (n) | Pearson’s chi-squared test | Statistical significance |
|---|---|---|---|---|
| Normal perfusion | 101 | 98 | ||
| Hypoperfusion | 31 | 34 | 79.119* | p < 0.001* |
| No perfusion | 28 | 18 | 42.307 | p < 0.001 |
| Excluded ROIs | 0 | 10 | ||
| Total | 160 | 160 |

Normal perfusion versus hypoperfusion.
CTP: perfusion computed tomography; MRP: magnetic resonance perfusion; UPI: ultrasound perfusion imaging.
