“…As data were normally distributed and the inter-observer variability was excellent (see Inter-observer agreement below), these differences can be imputed to significant inter-subject variability, which is also often observed in other tracts of the GI system. 10,48,49 Inter-observer agreement Our analysis showed an excellent agreement in total gastric volumes between the two observers, defined by an overall Dice similarity coefficient of 0.938. Our observed coefficient is significantly higher than 0.7, defined in the literature as a good overlap.…”

Background Gastric motility and accommodation have a critical role in maintaining normal gastrointestinal homeostasis. Different modalities can be adopted to quantify those processes, i.e., scintigraphy to measure emptying time and intragastric Barostat for accommodation assessment. However, magnetic resonance imaging (MRI) can assess the same parameters non-invasively without ionizing radiation. Our study aimed to develop a detailed three-dimensional (3D) MRI model of the stomach to describe gastric volumes, surface areas, wall tension distribution, and inter-observer agreement. Methods Twelve healthy volunteers underwent an MRI protocol of six axial T2-weighted acquisitions. Each dataset was used to construct a 3D model of the stomach: Firstly, the volumes of the whole stomach, gastric liquid, and air were segmented. After landmark placing, a raw 3D model was generated from segmentation data. Subsequently, irregularities were removed, and the model was divided into compartments. Finally, surface area and 3D geometry parameters (inverse curvatures) were extracted. The inverse curvatures were used to as a proxy for wall tension distribution without measuring the intragastric pressure. Key Results The model was able to describe changes in volume and surface geometry for each compartment with a distinct pattern in response to filling and emptying. The surface tension was distributed non-homogeneously between compartments and showed dynamical changes at various time points. Conclusion & Inferences The presented model offers a detailed tool for evaluating gastric volumes, surface geometry, and wall tension in response to filling and emptying and will provide insights into gastric emptying and accommodation in diseases such as diabetic gastroparesis.

“…This could be because individuals underwent the necessary fasting period for emptying the stomach before UGI. Some studies argument an average time of 248........39...min 7 and 276.4........58.9...min 10 for emptying the stomach. However, even after an average time of 490.2........214.2...min, liquid content of about 17........21...mL was found in the stomach of 18 patients.…”

“…Twenty one studies describing gastric emptying times of various kinds of foods were identified. [ 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 ] Of these, 14 were RCTs and 7 were observational studies. These studies used various methods of gastric emptying estimation such as the 'gold standard' scintigraphy, MRI, GUS and carbon dioxide breath analysis.…”
