Table 1 Comparison of intravenous contrast-enhanced C-arm computed tomography and multidetector computed tomography for the assessment of ablative areas and margins in radiofrequency ablation of liver tumors (mean ± SD)

	C-arm computed tomography	Multidetector computed tomography	P value
Mean long axis (mm)	28.1 ± 8.1	27.3 ± 8.1	0.134
Mean short axis (mm)	19.9 ± 4.8	19.3 ± 5.1	0.161
Mean estimated ablative area (mm²)	462.5 ± 202.1	441.2 ± 212.5	0.206
Mean ablative margin (mm)	6.4 ± 2.2	6.0 ± 2.4	0.159
Insufficient safety margin detection (%)	39.6 (19/48)	41.6 (20/48)	0.569
