Figures
- Fig 1.
Visual scale for grading SSI in supraventricular sulci: 0 = complete nulling, 1 = stippled hyperintensity, 2 = stippled with areas of confluent hyperintensity, 3 = confluent hyperintensity in sulci. The same grading scale was applied to precontrast and postcontrast FLAIR images.
- Fig 2.
Relationship of CBV with pre-contrast (A) and post-contrast (B) FLAIR SSI. Significant correlations (P < .05) are in black.
