Inter-and Intra-Observers Reproducibility of MRI for the Measurement of NET Liver Metastases Abstract #759

Introduction: Assessment of treatment is based on metastases size measurement.
Aim(s): Our goal was to determine the intra and inter-observers reproducibility of each MRI sequence for the measurement of NET liver metastases.
Materials and methods: Thirty-two patients with NET liver metastases underwent 1.5-T MR imaging of the liver (T2W and T1W sequences before and after the injection of gadolinium on hepatic arterial (HAP) and portal venous phase (PVP)). A maximum of five target lesions by patient was chosen by one reviewer on the MR sequence allowing the better depiction. Then measurements of target lesions diameter were performed by three reviewers blindly and independently in two sessions with a delay of one month.
