Sensitivity of common imaging modalities used in the evaluation of gastroenteropancreatic neuroendocrine neoplasms

Imaging modality	Sensitivity
Transabdominal USG	13%-27% for GEPNEN
Contrast enhanced ultrasound	99% in detecting liver metastases
Endoscopic ultrasonography	82%-93% for PNEN
CECT	63%-82% for PNEN
CE MRI	79% for PNEN
DWI	83% for liver metastases

USG: Ultrasonography; GEPNEN: Gastroenteropancreatic neuroendocrine neoplasms; CECT: Contrast enhanced computed tomography; CE MRI: Contrast-enhanced magnetic resonance imaging; DWI: Diffusion-weighted imaging.
