A selection of parametric models are provided that combine a compartmental
model for tissue and a functional form of the arterial input function.
Arguments
type |
is a character string that identifies the type of compartmental
model to be used. Acceptable models include:
- "weinmann"
Weinmann AIF convolved with a single compartment
(Kety) model
- "extended"
Kety model extended with additional vascular
compartment (default)
- "orton.exp"
Extended model using Orton's exponential arterial
input function
- "orton.cos"
Extended model using Orton's raised cosine arterial
input function
- "kety.orton.exp"
Kety model using Orton's exponential arterial
input function
- "kety.orton.cos"
Kety model using Orton's raised cosine
arterial input function
- "weinmann.empirical"
User-specified empirical AIF convolved
with a single compartment model
- "extended.empirical"
Extended model with user-specified
empirical arterial input function
|
Value
A function.
Details
Parametric models from the DCE-MRI literature are provided to the user for
kinetic parameter estimation. All models, with the exception of those
marked ‘empirical’ incorporate a parametric model for the arterial
input function (AIF).
