Dynamic Three-Dimensional Contrast-Enhanced Ultrasound to Predict Therapeutic Response of Radiofrequency Ablation in Hepatocellular Carcinoma: Preliminary Findings

Table 3

Comparison of the diagnostic efficacy of 2D-CEUS and 2D-CEUS combined with 3D-CEUS.

Diagnostic performance	2D-CEUS	2D-CEUS + 3D-CEUS
Sensitivity	6/9 (66.7 %)	6/6 (100 %)
Specificity	30/33 (90.9 %)	33/36 (91.7 %)
PPV	6/9 (66.7 %)	6/9 (66.7 %)
NPV	30/33 (90.9 %)	33/33 (100 %)
Accuracy	36/42 (85.7 %)	39/42(92.9 %)

2D-CEUS: two-dimensional contrast-enhanced ultrasound; 3D-CEUS: three-dimensional contrast-enhanced ultrasound; PPV: positive predictive value; NPV: negative predictive value.
