| [ Summary ] |
FDG-PET is now widely employed in clinical oncology. The applicability of FDG-PET for the evaluation of malignant lymphoma is well established and may replace conventional 67Ga scintigraphy. Low grade lymphoma of the gastrointestinal tract is sometimes difficult to detect with FDG-PET due to the physiological uptake of the gastrointestinal tract. However, it is still useful for the evaluation of treatment response and follow-up observation. A positive FDG-PET scan after the completion of treatment is a strong predictor of relapse. Information concerning tumor glucose metabolism provides an early sign of relapse, resistance to therapy and conversion to more aggressive high grade disease. Such information has been difficult to achieve with conventional morphological imaging techniques such as CTs. |
