dcmri.perfusion(parameter='Fb', tissue='gray matter') → float[source]#

perfusion parameters of selected tissue types.

Parameters:

  • parameter (str, optional) – perfusion parameter. Options are ‘Fb’ (blood flow), ‘vb’ (Blood volume), ‘PS’ (permeability-surface area product) and ‘vi’ (interstitial volume). Defaults to ‘Fb’.

  • tissue (str, optional) – Tissue type. Defaults to ‘gray matter’.

Raises:

ValueError – If the requested parameter values are not available.

Returns:

parameter value in standard units

Return type:

float

Example

>>> import dcmri as dc
>>> print('The BF of gray matter is', dc.perfusion('Fb', 'gray matter'), 'mL/sec/mL')
The BF of gray matter is 0.01 mL/sec/mL
