The relation between the tumour size and the extent of 11C-methyl methionine (MET) area of the patients with glioblastoma multiforme
| Case No | Age (years)/sex | Location of tumour | Max tumour diameter (mm) | SOR (%) of MET area within x mm outside Gd area* | Type of relation between MET area and T2-high area† | ||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| 0 mm | 5 mm | 10 mm | 15 mm | 20 mm | 25 mm | 30 mm | |||||
| *SOR (%) of MET area within x mm outside the Gd area = sum of the size of the MET area within x mm outside the Gd area in each slice/sum of the size of the MET area in each slice. | |||||||||||
| †Type 1, the MET area and T2-high area were not coincident; type 2, the MET area was completely within the T2-high area. | |||||||||||
| F, female; Gd area, area of gadolinium enhancement on T1 weighted image; L, left; M, male; max, maximum; MET area, the area of increased 11C-methyl methionine accumulation on positron emission tomography; R, right; SOR, size occupation ratio; T2-high area, the area of high signal intensity on T2 weighted image. | |||||||||||
