Correlation of microvessel area and perfusion parameters
| Perfusion Parameters | CASL: % Signal Change | CASL: rCBF | T2DSC: rCBV | T2DSC: rCBF | T2DSC: MTT |
|---|---|---|---|---|---|
| r2 | .91 | .61 | .83 | .73 | .29 |
| Significance of correlation | P < .00001 | P < .001 | P < .0001 | P < .001 | P < .05 |
Note:—r2: Squared Pearson’s correlation coefficient. Significance of correlation; t test for simple linear regression was performed. The p-value is calculated using the t-distribution.
CASL indicates continuous arterial spin labeling; T2DSC, T2-dynamic susceptibility contrast; rCBF, right cerebral blood flow; rCBV, right cerebral blood volume; MTT, mean transit time.
