Letter to the Editor

Dear Sir,

We have read with great interest the paper by Ho and colleagues describing the usefulness of dual tracer 11C-acetate and 18F-FDG PET-CT for the individualized dose calculation in patients affected by hepatocellular carcinoma submitted to treatment with 90Y-labeled glass microspheres [1]. We would like to congratulate the authors for this publication and thank them for focusing on a relevant question. The two tracers (i.e., 11C-acetate and 18F-FDG) were proposed as complementary biochemical probes to characterize hepatocellular carcinoma before undergoing the administration of 90Y-labeled glass microspheres, as the more aggressive hepatocellular lesions are generally 18F-FDG-avid, while the more differentiated ones can be visualized using 11C-acetate.

A growing amount of scientific data concerning 90Y-radioembolization in hepatocellular carcinoma has demonstrated its significant impact on outcomes [2]. To date, 90Y-radioembolization represents a well-standardized procedure in...
