Figures
- FIG 1.
Sample measurements of the SATNaPT. Sagittal SSFP MR images show a normal angle of 166° (A) and a decreased angle of 120° (B). The angle measurements are shown below the nerves to avoid obscuring the anatomy.
- FIG 2.
Histogram of SATNaPT in different patient populations. The horizontal axis angle is measured in 5° intervals. The vertical axis is the percentage of patients. A best-fit normal curve is also shown for each histogram. Note that all curves are similar except the cTN curve, which has a bimodal distribution in which 17% of the nerves form a separate population with decreased SATNaPT. Asympt indicates the contralateral asymptomatic nerve in patients with cTN; Control, patient scanned for other reasons; Combined, all asymptomatic nerves (control plus Asympt).
