Microwave Thermoablation of Colorectal Liver Metastases Close to Large Hepatic Vessels Under Pringle Maneuver Minimizes the "Heat Sink Effect".

Background: Liver resection and thermoablation are the mainstay of the surgical management of colorectal liver metastases (CRLM). The main limitation of thermoablation is the "heat-sink" effect for nodules next to large vessels. Herein, we report the preliminary results of microwave ablation (MWA) with associated Pringle maneuver to overcome this flaw.

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.
