Figures
- Fig 1.
A 23-year-old woman with an anaplastic astrocytoma. T2-weighted MR image (A) reveals a tumor of the spinal cord from the eighth thoracic vertebra to the first lumbar vertebra (white arrows). A contrast-enhanced T1-weighted MR image with fat saturation (B) shows mild contrast enhancement of the tumor (white arrows). FDG-PET (C) and MET-PET (D) reveal increased activity of both FDG (SUVmax = 7.4) and MET (SUVmax = 3.2) of the tumor (white arrows). A fusion image of FDG-PET and contrast-enhanced T1-weighted MR imaging with fat saturation (E) clearly shows increased uptake of FDG in the tumor.

A 56-year-old man with an ependymoma. A contrast-enhanced T1-weighted image (A) shows a tumor from the first to fifth cervical vertebra with a cystic and solid component (white arrows). Contrast enhancement of the solid component at the second cervical vertebra is seen (white arrows). FDG-PET (B) and MET-PET (C) show accumulation of both FDG (SUVmax = 11.2) and MET (SUVmax = 2.2) (white arrows).
- Fig 3.
A 12-year-old girl with a cavernous angioma. A T2-weighted MR image (A) shows a mainly hypointense tumor (white arrows) at the twelfth thoracic vertebra. Hypointensity may be due to hemosiderin deposition. A hyperintense area surrounding the hypointense lesion seems to be edema, but its histologic evidence was not acquired. Although accumulation of MET is not evident (B), FDG-PET (C) shows slight activity of the tumor (SUVmax = 5.2) (black arrow).
