The value of F-18FDG triple-haed coincidence PET in the posttreatment evaluation of patients with lymphoma

We performed a single centre study comprised 31 consecutive patients with lymphoma within 3 months after completion of conventional initial therapy or after salvage therapy with high-dose chemotherapy. PET studies were done by using fluorine-18-fluorodeoxyglucose (FDG) and hybrid PET camera with triple head coincidence imaging capability. The long-term follow-up data (at least 12 months, median 20 months) were extracted from the patients’ medical files. Fifteen patients were FDG - negative, 12 were positive and in four patients only slightly increased FDG uptake was observed (equivocal findings – two relapsed). Besides all shortcomings of coincidence PET, we found this hybrid PET methodology good enough for reliable prognosis in follow-up of our patients, especially in those without FDG pathological fixation.
