Population: Data analysis only for a subset of patients with HCC undergoing hepatic resection compared to healthy controls. Oxygen uptake for HCCs is reported in patients, and oxygen uptake for the liver is reported in volunteers. R1 measurements method in the volunteers proved unreliable - therefore no data available for T1/R1 in the healthy participant arm.

Tumor diffusion measured with diffusion-weighted imaging sequence. In diffusion weighted MR imaging (DWI), the signal is proportional to the Brownian motion diffusion of free water protons in tissues. Deposition of collagen in tissue (as in fibrotic disease), or cellularity in tumors act as impediments to free water diffusion. Using different mathematical models, the degree of diffusion can be quantified from the MRI signal, to provide information on diffusion restriction due to disease. From mono exponential fit of diffusion signal, one can obtain the apparent diffusion coefficient (ADC). However, this coefficient reflects free water proton diffusion, as well as transport of water protons in the capillary vessels (capillary perfusion).

Tumor diffusion measured with diffusion-weighted imaging sequence. To separate the diffusion effect from capillary perfusion, a bi-exponential model is used, which provides 3 coefficients: one is the true diffusion coefficient D, reflecting free water proton diffusion.

Tumor diffusion measured with diffusion-weighted imaging sequence. To separate the diffusion effect from capillary perfusion, a bi-exponential model is used, which provides 3 coefficients: one is the perfusion fraction PF, which reflects how much the diffusion-weighted signal is affected by capillary perfusion. PF is a measure of vascularity in the tissue.

Tumor response to treatment is evaluated clinically by radiologists according to RECIST and modified RECIST criteria, by which the diameter of the tumor portion that enhances (lights up on imaging) after administration of gadolinium contrast agent is measured before and after treatment. The response is not reported as diameter or diameter difference in mm, but rather as a qualitative variable: complete response, partial response, stable disease and progressive disease. Complete response means no enhancing tumor regions after treatment (i.e. complete tumor necrosis, no more vascular regions of the tumor that take up contrast), partial response is a decrease in the diameter of the enhancing region, stable disease is unchanged diameter, and progressive disease is an increase in the diameter of the enhancing region after treatment.
