Sensitivities of the various imaging modalities for locating specific NETs80 84–92

Pancreatic NETsTumour and Frequency
 Dual-phase multi-detector CT57–94%
 SSRS insulinomas50–60%
 SSRS gastrin/VIP/somatostatin75%
68Ga DOTATOC PET87–96%
Primary gastrointestinal NETs
 CT enteroclysis85%
 MR enteroclysis86%
 SSRS for detection of lesions in non-pancreatic GI NETs86–95%
Neuroendocrine liver metastases
  • EUS, endoscopic ultrasound; GI, gastrointestinal; MR, magnetic resonance; NET, neuroendocrine tumour; PET, positron emission tomography; SSRS, somatostatin receptor scintigraphy; VIP, vasoactive intestinal peptide.

  • All of the above sensitivities for detecting tumour are further enhanced by intraoperative ultrasound.
