Prospective comparison of whole-body MRI with diffusion-weighted and conventional imaging for the follow-up of neuroendocrine tumors.

Aim: To determine whether whole-body magnetic resonance imaging is valuable in staging of neuroendocrine tumors by comparison with the conventional imaging defined by the combination of computed tomography and somatostatin receptor scintigraphy.

Methods: This study concerned the patients included in the multicenter prospective study NCT02786303 with the following inclusion criteria: well-differentiated gastroenteropancreatic neuroendocrine tumors or of unknown primary, and computed tomography, whole-body magnetic resonance imaging and somatostatin receptor scintigraphy performed within 6 weeks. Results of the conventional imaging were compared with those of magnetic resonance imaging.
