How to Perform Contrast Enhanced Oncologic Staging MRI of Abdomen and Pelvis with a Hepatocyte Specific Agent in a Large Bore MR Scanner: Optimizing Extrahepatic Tumor Evaluation in Neuroendocrine Neoplasms

#2113

Introduction: Liver specific MR contrast agents in neuroendocrine neoplasms (NEN) have shown its advantages in evaluation of hepatic tumor burden. However, a standard scan protocol is insufficient in extrahepatic and especially pelvic tumor evaluation.

Aim(s): To evaluate a MRI shuttle protocol with fast 3D-T1w sequences and hepatospecific contrast (Gd-EOB) to enable imaging abdomen and pelvis in optimal first pass contrast phases in the setting of a large bore MRI scanner with shorter axial field of view.

Materials and methods: 96 patients with NEN of the abdomen were scanned with the first pass (FP) pelvic sequence in a Gd-EOB MRI. We compared pelvic vessel and tissue enhancement between FP and a standard equilibrium (EQ) pelvic sequence. Dynamic liver enhancement between the new protocol including FP pelvic sequence was compared to a standard protocol without additional sequence.
