From: Performance of 18 F-FAPI PET/CT in assessing glioblastoma before radiotherapy: a pilot study
The 18 F-FAPI PET/CT and MRI (T2, FLAIR, CE-T1) images of patient 6. A1–D1 were images of T2 sequence, A2–D2 were images of FLAIR, A3–D3 were images of enhanced T1, A4–D4 were images of 18 F-FAPI PET, A5–D5 were images of non-enhanced CT, A6–D6 were images of fusion of 18 F-FAPI PET and CT. The patient underwent incomplete surgical resection of the glioblastoma in the right frontal lobe. Four lesions were detected on MRI (A1-D1, short arrow, yellow arrow, red arrow, and asterisk). Only one 18 F-FAPI-avid lesion was observed on PET/CT (orange arrow, A4-A6).
