Per-operating Use of a Probe for Detection of β+

The objective of the study is to evaluate the sensibility of the probe Forimtech to detect β+ emission in vivo in humans and its usefulness during elective surgical procedure Hypothesis:The probe Forimtech is able to allow per-surgery detection of tumoral lesions sensible to 18F-FDG and to help in the realization of guided biopsies, minimally invasive surgery or complement of resection of tumors. The β+ emission detected by the probe Forimtech is correlated to the emission γ detected by the 18F-FDG.PET/CT
