Values are taken from literature, mostly from Stanisz et al 2005

Parameters:

field_strength (float, optional) – Field strength in Tesla (see below for options). Defaults to 3.0.
tissue (str, optional) – Tissue type (see below for options). Defaults to ‘blood’.
Hct (float, optional) – Hematocrit value - ignored when tissue is not blood. Defaults to 0.45.

Raises:

ValueError – If the requested T1 values are not available.

Returns:

T1 values in sec

Example

>>> import dcmri as dc
>>> print('The T1 of liver at 1.5T is', 1e3*dc.T1(1.5, 'liver'), 'msec')
The T1 of liver at 1.5T is 602.0 msec
