Clinical - rifampicin induced inhibition of liver function#
This example illustrates the use of AortaLiver2scan for joint
fitting of aorta and liver signals measured over 2 separate scans. The use
case is provided by the liver work package of the
TRISTAN project which develops imaging
biomarkers for drug safety assessment. The data and analysis was first
presented at the ISMRM in 2024 (Min et al 2024, manuscript in press).
The data were acquired in the aorta and liver of 10 healthy volunteers with dynamic gadoxetate-enhanced MRI, before and after administration of a drug (rifampicin) which is known to inhibit liver function. The assessments were done on two separate visits at least 2 weeks apart. On each visit, the volunteer had two scans each with a separate contrast agent injection of a quarter dose each. the scans were separated by a gap of about 1 hour to enable gadoxetate to clear from the liver. This design was deemed necessary for reliable measurement of excretion rate when liver function was inhibited.
The research question was to what extent rifampicin inhibits gadoxetate uptake rate from the extracellular space into the liver hepatocytes (khe, mL/min/100mL) and excretion rate from hepatocytes to bile (kbh, mL/100mL/min).
2 of the volunteers only had the baseline assessment, the other 8 volunteers completed the full study. The results showed consistent and strong inhibition of khe (95%) and kbh (40%) by rifampicin. This implies that rifampicin poses a risk of drug-drug interactions (DDI), meaning it can cause another drug to circulate in the body for far longer than expected, potentially causing harm or raising a need for dose adjustment.
Note: this example is different to the 1 scan example of the same study in that this uses both scans to fit the model.

Model definition#
In order to avoid some repetition in this script, we define a function that returns a trained model for a single dataset with 2 scans:
def tristan_human_2scan(roi, par, **kwargs):
model = dc.AortaLiver2scan(
# Injection parameters
weight = par['weight'],
agent = 'gadoxetate',
dose = par['dose_1'],
dose2 = par['dose_2'],
rate = 1,
# Acquisition parameters
field_strength = 3,
t0 = par['t0'],
TR = par['TR'],
FA = par['FA_1'],
FA2 = par['FA_2'],
TS = roi['time_1'][1]-roi['time_1'][0],
# Signal parameters
R10a = 1/par['T1_aorta_1'],
R10l = 1/par['T1_liver_1'],
R102a = 1/par['T1_aorta_3'],
R102l = 1/par['T1_liver_3'],
# Tissue parameters
vol = par['liver_volume'],
)
xdata = (
roi['time_1'][roi['aorta_1_accept']] - roi['time_1'][0],
roi['time_2'][roi['aorta_2_accept']] - roi['time_1'][0],
roi['time_1'][roi['liver_1_accept']] - roi['time_1'][0],
roi['time_2'][roi['liver_2_accept']] - roi['time_1'][0],
)
ydata = (
roi['aorta_1'][roi['aorta_1_accept']],
roi['aorta_2'][roi['aorta_2_accept']],
roi['liver_1'][roi['liver_1_accept']],
roi['liver_2'][roi['liver_2_accept']],
)
model.train(xdata, ydata, **kwargs)
return xdata, ydata, model
Before running the full analysis on all cases, lets illustrate the results by fitting the baseline visit for the first subject. We use maximum verbosity to get some feedback about the iterations:

Fit all data#
Now that we have illustrated an individual result in some detail, we proceed with fitting the data for all 10 volunteers, at baseline and rifampicin visit. We do not print output for these individual computations and instead store results in one single dataframe:
results = []
# Loop over all datasets
for subj in rois.keys():
for visit in rois[subj].keys():
roi = rois[subj][visit]
par = pars[subj][visit]
# Generate a trained model for the scan:
_, _, model = tristan_human_2scan(roi, par, xtol=1e-3)
# Export fitted parameters as lists
rows = model.export_params(type='list')
# Add visit and subject info
rows = [row + [visit, subj] for row in rows]
# Add to the list of all results
results += rows
# Combine all results into a single dataframe.
cols = ['parameter', 'name', 'value', 'unit', 'stdev',

results = pd.DataFrame(results, columns=cols)

Now lets visualise the main results from the study by plotting the drug
effect for all volunteers, and for both biomarkers: uptake rate khe
and excretion rate kbh:
