T2 relaxometry times in 30 healthy control volunteers
Right Side | Left Side | Asymmetry Index* | Mean | Cutoff T2† | |
---|---|---|---|---|---|
Hippocampus | 98 (±2.7) | 97 (±3.5) | −0.01 (±0.03) | 98 (±2.8) | ≥107 |
Anterior temporal lobe | 76 (±3.5) | 75 (±3.8) | −0.01 (±0.06) | 75 (±2.8) | ≥84 |
Frontal white matter | 76 (±3.8) | 75 (±3.1) | −0.01 (±0.02) | 76 (±3.4) | ≥87 |
Parietal white matter | 91 (±4.4) | 91 (±4.0) | 0.00 (±0.03) | 91 (±4.0) | ≥103 |
* Asymmetry index = (L − R)/(L + R).
† Cutoff value, 3 SD above mean of control values.
