The study aimed to assess how fused images from CT and FDG-PET scans can help in defining gross tumor volume (GTV) and clinical target volume (CTV) for radiation therapy planning.
Involving 28 patients with lung cancer and non-Hodgkin's lymphoma, the research found that PET scans changed the GTV or CTV in 44% of cases, impacting treatment strategies.
The results highlight that FDG-PET offers enhanced visualization of tumor spread, confirming that combining CT and PET imaging can significantly improve radiation therapy planning and overall patient management.
