FAPI-PET/CT superior to FDG-PET/CT in assessing liver cancer

A recent study suggests that PET/CT imaging with a FAPI radiotracer is superior to F-18 FDG-PET/CT for assessing patients with liver cancer.

Two cases of pathologically confirmed intrahepatic cholangiocarcinomas in 68-year-old male patients. In both cases (A-H, case 1; I-P, case 2), CT scans (B, F, case 1; J, N, case 2) revealed intrahepatic bile duct dilation and suspected nodular lesions. While F-18 FDG PET/CT (A, C, D, case 1; I, K, L, case 2) failed to demonstrate abnormal tracer uptake (SUVmax 3.5, TBR 1.3 in Case 1; SUVmax 2.6, TBR 1.2 in Case 2), F-18 FAPI-04 PET/CT (E, G, H, case 1; M, O, P, case 2 ) showed positive uptake in the nodular lesions (SUVmax 9.7, TBR 3.5 in Case 1; SUVmax 9.6, TBR 3.3 in Case 2).

Representative maximum-intensity projections of five patients (patients 3, 5, 7, 10, and 11) comparing Ga-68 NYM046 and F-18 FDG. Both tracers showed specific retention in bone and lymph node metastases (patients 10 and 11). Ga-68 NYM046 PET/CT outperformed F-18 FDG PET/CT in detecting primary tumors, lung metastases, and pleural metastases (patients 3, 5, 7, and 11).
