Manometric tube and axial force catheter used by Marciani et al (2000)
In vivo methods to assess gastric disintegration and emptying rate • Feeding study – acquiring the digesta samples using naso-gastric • Intubation techniques: gastric barostat and intraluminal manometry – “gold standards” for assessing motility of the stomach • Scintigraphic imaging: liquid barium sulphate, radioopaque spheres – standard method to measure gastric emptying • Ultrasonography measures gastric volume or antral crosssection. The information is used to estimate the rate of emptying and evaluate antral motility. • Magnetic resonance imaging (MRI) • Indirect methods such as blood test and breath test
