Do neuroendocrine tumors show up on MRI?

Magnetic resonance imaging

MRI is the best conventional study to detail hepatic metastases in NETs (Figure 2) [12]. It is not as useful as CT for the detection of primary small bowel lesions or their associated lymphadenopathy, but is good for the detection of primary pancreatic NETs.
