Subjective assessment of high- and low-SAR FSTIR images of DBS candidates by various readers and percentage of patients rated for low-SAR images being higher (L > H), lower (L < H), or of equal utility (L = H) for radiologic assessments
| Readers | STN and RN (Low vs High SAR) | GP (Low vs High SAR) | Temporal Cortical GM, CN, and Put (Low vs High SAR) | Ventricular Fluid Intensity and CSF/Tissue Margins |
|---|---|---|---|---|
| Neuroradiologist 1 | L > H (31%) | L > H (23%) | L > H (23%) | L > H (85%) |
| L < H (15%) | L < H (15%) | L < H (23%) | ||
| L = H (54%) | L = H (62%) | L = H (54%) | L = H (15%) | |
| Neuroradiologist 2 | L > H (23%) | L > H (15%) | L > H (31%) | L > H (85%) |
| L < H (23%) | L < H (15%) | |||
| L = H (54%) | L = H (85%) | L = H (54%) | L = H (15%) |
Note:—L indicates low; H, high; RN, red nucleus; CN, caudate head; Put, putamen; GP, globus pallidus.
