Brain and cervical cord magnetization transfer and diffusion tensor MR imaging-derived metrics from patients with neuroborreliosis and from healthy volunteers
MR Imaging Metrics | Healthy Volunteers (SD) | Patients with Neuroborreliosis (SD) |
---|---|---|
NAWM average MTR (%) | 43.2 (1.2) | 41.1 (1.9) |
GM average MTR (%) | 38.4 (1.2) | 36.9 (1.5) |
NAWM average MD (×10−3 mm2 s−1) | 0.82 (0.03) | 0.84 (0.04) |
GM average MD (×10−3 mm2 s−1) | 0.10 (0.05) | 0.10 (0.07) |
NAWM average FA | 0.29 (0.02) | 0.29 (0.02) |
