Indirect vs direct assessment of gastric emptying: A randomized crossover trial comparing C ‐isotope breath analysis and MRI

Conclusions & InferencesBT can assess relative emptying differences on group level and collecting breath data for 90 minutes constitutes a lower burden for participants and the research facility. However, BT has severe shortcomings compared to MRI for individual GE assessment. Notably, food matrix effects should be considered when interpreting the results of BT. Our aim was to assess similarity in assessment of gastric emptying between 90‐min 13C breath analysis and MRI among four liquid meals. On group level both measurement methods show similar order of emptying times, however, both t50 times and rankings within a participant differed significantly between methods.
