# Half-emptying time t50 from Maes/Ghoos fit with scintigraphic correction

`t50_maes_ghoos_scintigraphy.Rd`

Half-emptying time t50 in minutes from beta exponential function fit, with linear and rather arbitrary correction for scintigraphic values. This is given for comparison with published data only; there is little justification to use it, even if it is closer to real gastric emptying times as determined by MRI or scintigraphy.
