Scatter plots show correlation of tumor enhancement changes in (a) early or arterial phase and (b) delayed or venous phase after TACE with doxorubicin-eluting beads, as measured with cone-beam CT (CBCT) and MR imaging. A decrease in tumor enhancement at cone-beam CT showed a linear correlation with findings at MR imaging. Estimated correlation coefficients were excellent for both arterial (R = 0.89, P < .0001) and venous (R = 0.82, P < .0001) phases.
