Sensitivities of the various imaging modalities for locating specific NETs^{80 84–92}

Pancreatic NETs	Tumour and Frequency
Dual-phase multi-detector CT	57–94%
MRI	74–94%
EUS	82–93%
SSRS insulinomas	50–60%
SSRS gastrin/VIP/somatostatin	75%
68Ga DOTATOC PET	87–96%
Primary gastrointestinal NETs
CT enteroclysis	85%
MR enteroclysis	86%
SSRS for detection of lesions in non-pancreatic GI NETs	86–95%
Neuroendocrine liver metastases
CT	44–82%
MRI	82–95%

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.
