Semiquantitative estimation of vascular reactivity by SPECT in 21 patients with ivy unsymmetric and ivy symmetric proliferation
| RI Mean | |
|---|---|
| Ivy unsymmetric (n = 14) | 0.80 ± 0.10* (Ivy dominant/ivy less dominant) |
| Ivy symmetric (n = 7) | 1.05 ± 0.16 (right/left) |
Note:—RI indicates (vascular) reactivity index; SPECT, single-photon emission CT.
* P < .05.
