Since paragangliomas including carotid body tumor are of neuroendocrine origin, they may have somatostatin surface receptor which can be detected as an area of intense radio-tracer uptake by the Indium-111 octreotide scan. This modality may be helpful in the diagnosis of multicentric or metastatic disease. It also may be used after the surgery to look for a residual tumor.
