Half-emptying time t50 from Maes/Ghoos fit with scintigraphic correction
Description
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.
Ghoos YF, Maes BD, Geypens BJ, Mys G, Hiele MI, Rutgeerts PJ, Vantrappen G.
Measurement of gastric emptying rate of solids by means of a carbon-labeled
octanoic acid breath test. Gastroenterology. 1993;104:1640-1647.
Usage
t50_maes_ghoos_scintigraphy(cf)
Arguments
cf
named vector of coefficients; only k and beta are required
Value
Time where value is 1/2 of maximum, i.e. t50 in minutes.
See Also
exp_beta, and t50_bluck_coward for an example.
