PET Tumor Grade | Frequency of SusE, n (%) | Conglomerates, n (%) | Total, n (%) | ||
---|---|---|---|---|---|
Low | Medium | High | |||
Low count | 3 (25) | 0 | 0 | 0 | 3 (25) |
Intermediate count | 0 | 1 (8.33) | 0 | 1 (8.33) | 1 (8.33) |
High count | 1 (8.33) | 0 | 7 (58.33) | 7 (58.33) | 8 (66.67) |
Total | 4 (33.33) | 1 (8.33) | 7 (58.33) | 8 (66.67) | 12 (100) |
Note:—SusE indicates susceptibility effects; PET, positron-emission tomography. Frequency of intralesional SusE, as well as formation of conglomerates correlated directly with tumor grade as determined by PET.
