From: Portable, bedside, low-field magnetic resonance imaging for evaluation of intracerebral hemorrhage
Manual pMRI hematoma volume versus (a1) cognitive status (NIHSS) at time of exam (pMRI T2W (n = 33): ρ = 0.750, 95% CI: [0.591–0.906], p = 4.95e-7; pMRI FLAIR (n = 34): ρ = 0.802, 95% CI: [0.669–0.930], p = 1.23e-8) and a2 functional status (mRS) at discharge (pMRI T2W (n = 36): ρ = 0.589, 95% CI: [0.372–0.804], p = 1.55e-4; pMRI FLAIR (n = 37): ρ = 0.641, 95% CI: [0.425–0.855], p = 1.89e-5). Averaged ABC/2 estimated pMRI hematoma volume versus (b1) cognitive status (NIHSS) at time of exam (pMRI T2W (n = 36): ρ = 0.805, 95% CI: [0.659–0.948], p = 3.18e-9; pMRI FLAIR (n = 34): ρ = 0.776, 95% CI: [0.617–0.930], p = 7.16e-8) and (b2) functional status (mRS) at discharge (pMRI T2W (n = 39): ρ = 0.747, 95% CI: [0.592–0.899], p = 4.85e-8; pMRI FLAIR (n = 37): ρ = 0.669, 95% CI: [0.483–0.853], p = 5.98e-6). Spearman correlations are reported for a1, a2, b1, and b2 with confidence intervals. Bands represent 95% confidence intervals.
