The current goldstandard in diagnostic imaging consists of PET/CT with somatostatin-analogues such as 68Ga-DOTATOC. Due to the superb soft tissue contrast of MRI and the tendency towards early liver metastases, promising results on retrospective PET-MRI-fusion have been suggested for NETs. Since this method is time consuming and often defective, it is rarely performed in clinical routine. This is the first study on integrated PET/MRI with 68Ga-DOTATOC demonstrating its potential in whole-body staging of NETs, especially in the detection of NET liver metastases.
