GRS had a higher tumour detection rate than SRS and PET in our study. GRS in combination with CT was most effective in the detection of metastatic MTC.

MR hydrometry is a promising noninvasive method of assessing fluid output as a measure of exocrine pancreatic function.

Overall, CT is similar or better than PET in our patients (dependent on the standard) while SRS is inferior to both other techniques. Our data are in agreement with publications that consider CT superior to PET in the diagnosis of metastatic MTC while other studies show superiority of PET. However, a combination of CT and PET seems to be the most appropriate non-invasive diagnostic approach in patients with MTC.

OBJECTIVE.Vertebral

Our study demonstrated the feasibility of measuring pancreatic output by MRH after stimulation with secretin. Moreover, a distinction between normal secretion and patients with chronic pancreatitis is possible.
