Semi-quantitative (SQ) grading used for the endolymphatic hydrops. The vertical columns show the different semi-quantitative (SQ) grades from 0 to 3 used [cf. Table 1; according to a classification first described in Kirsch et al. (9)]. The horizontal rows each give an overview of how each grade looks (A), in FLAIR raw data (B), after VOLT processing (C), as used for 2D quantification (D), and as used for 3D quantification (E). A detailed description of each grade is given in the second paragraph of subsection ‘Semi-quantitative Grading of the Endolymphatic Space'.
