Estudio de extensión y valoración de la respuesta terapéutica en un paciente con adenocarcinoma pulmonar metastásico mediante estudio secuencial con 18F-FDG PET-TC y 18F-fluoruro PET-TC

We report a case of a patient with lung adenocarcinoma and bone and extraosseus metastases studied with 18F-FDG PET-CT, 99mTc-HMDP and 18F-fluoride PET-CT. It assesses the usefulness of 18F-FDG PET-CT for initial staging of the disease and monitoring response to therapy. For the study of the sclerotic bone metastases it shows the superiority of 99mTc-HMDP bone scintigraphy and 18F-fluoride PET-CT over 18F-FDG PET-CT, and 18F-fluoride PET-CT over bone scintigraphy. It also shows the usefulness of 18F-fluoride PET-CT for monitoring the bone metastases.
