Shift between irradiation effect and planned dose distribution

	T1-w	T2-w
n =	47	49
Axial shift/mm	-5.3 ± 5.4	-5.6 ± 6.0
Orthogonal shift/mm	4.0 ± 2.5	4.6 ± 2.6
Total shift/mm	7.7 ± 4.4	8.4 ± 4.4
ACS	1.14 ± 0.43	1.04 ± 0.49

Mean axial, orthogonal, and total shift between center coordinates of the irradiation effect and planned dose distribution in relation to the direction vector of catheter implantation for T1-w and T2-w MRI data. Both follow-up dates, 6w and 12w, were evaluated together. A negative value of the axial shift indicates a shift into the direction of the catheter entry site. T1-w = hepatocyte dysfunction, T2-w = interstitial edema, n = number of MR examinations assessed.
