Observation of the effect of targeted therapy of 64-slice spiral CT combined with cryoablation for liver cancer

Table 1 Postoperative ice coverage of different tumor sizes

Groups	Tumor diameter (cm)	Number of tumors (count)	ice coverage (%)			Effective rate
			100	80-99	< 80
Dual-slice group	< 3	38	19	12	7	81.58%
	≥ 3	27	17	8	2	92.59%
64-slice group	< 3	42	30	9	3	92.86%a
	≥ 3	35	26	7	2	94.29%

Effective rate = (ice coverage ≥ 80% of the tumor volume in the number of tumors)/(the total number of tumors) × 100%.

^aP < 0.05, vs the dual-slice group.
