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

Figure 3 Local weighted scatterplot smoothing line of martingale residuals for enhanced tumor volume% before the first transcatheter arterial chemoembolization treatment. A: Martingale residual local weighted scatterplot smoothing line for enhanced tumor volume%; B: The critical value of enhanced tumor volume% before and after transcatheter arterial chemoembolization treatment with magnetic resonance bias field correction.
