Magnetic resonance imaging bias field correction improves tumor prognostic evaluation after transcatheter arterial chemoembolization for liver cancer

Figure 2 Enhanced tumor volume before the first transcatheter arterial chemoembolization treatment. A: Martingale residual local weighted scatterplot smoothing line of enhanced tumor volume before the first transcatheter arterial chemoembolization treatment; B: Enhanced tumor volume threshold before the first transcatheter arterial chemoembolization treatment corrected using bias field.
