Description of intervention(s) / exposure
Other interventions - 99mTc-mebrofenin hepatobiliary scintigraphy (HBS)
Other interventions - Indocyanine Green
Other interventions - Liver Elasticity

Patients with Cancers in Liver - Adult patients with primary liver cancer or liver metastases from any other histology who will be measured before and after Radiotherapy by '99mTc-mebrofenin hepatobiliary scintigraphy (HBS), Indocyanine Green and Liver Elasticity.

Other interventions: 99mTc-mebrofenin hepatobiliary scintigraphy (HBS)
99mTc-mebrofenin HBS is a SPECT imaging procedure that allows evaluation of global and local liver function. Mebrofenin, bound to albumin, is taken up by hepatocytes in a similar manner to organic anions such as bilirubin. After hepatic uptake, the mebrofenin is excreted into the bile canaliculi. Dynamic imaging tools allow measurement of clearance rates for global function, and 3D SPECT imaging with corresponding CT allows visualisation of the local liver function with respect to anatomy. HBS allows direct visualisation of hepatocyte function.

Other interventions: Indocyanine Green
ICG is a fluorescent dye injected into the patient. The dye is exclusively excreted by the liver. The ICG clearance rate is measured in the finger of the subject.

Other interventions: Liver Elasticity
This is an Ultrasound measurement of the elasticity of the liver.

Primary outcome [1] 0 0
Change in global and local liver function - 99mTC-mebrofenin hepatobiliary scintigraphy images after stereotactic ablative body radiotherapy to cancers of the liver. This will be reported as a change in function as a function of delivered radiotherapy dose.
Timepoint [1] 0 0
3 years
Secondary outcome [1] 0 0
Correlation between 99mTC mebrofenin HBS and various measures of global function - This correlation will be measured using liver elasticity, Indocyanine Green (ICG) and Child-Pugh and Model for End stage Liver Disease (MELD) scores
Timepoint [1] 0 0
3 years
Secondary outcome [2] 0 0
Relationship between radiological features on CT images and SPECT images - Relationship between radiological features or changes visable on computed tomography (CT) image data and changes in local liver function as observed on 99mTC mebrofenin HBS.
Timepoint [2] 0 0
2 years
Secondary outcome [3] 0 0
Radiotherapy dose sparing of functional liver - The amount of sparing of dose to functional liver that can be achieved using 99mTC Mebrofenin HBS to guide treatment plan optimisation will be evaluated.
