[Imaging and radioguided surgery of tumors NETs].

Neuroendocrine tumors tend to grow slowly and are notoriously difficult to localize, at least in the early stages. Metastases are in most cases already present at the time of diagnosis. Somatostatin receptor scintigraphy improves detection of small and occult NET tumors. Intraoperative probe counting with a hand-held gamma probe can identify tumors even when they are small and impalpable, but receptor positive. This advanced operative approach may improve the survival of these patients.
