Clinical Study
Dynamic Three-Dimensional Contrast-Enhanced Ultrasound to Predict Therapeutic Response of Radiofrequency Ablation in Hepatocellular Carcinoma: Preliminary Findings
Table 2
Contrast appearances of 42 HCC lesions observed by two modalities of CEUS and the corresponding SOR results.
| Contrast enhancement pattern | Number of lesions |
| RT confirmed by SOR | 9 | Nodular enhance pattern(RT) | | Observed on 2D-CEUS alone (not successfully displayed on 3D-CEUS) | 3 | Observed on 3D-CEUS alone (not observed on 2D-CEUS) | 3 | Observed on both 2D-CEUS and 3D-CEUS | 3 |
| CR confirmed by SOR | 33 | Rim enhanced pattern (CR) | | Thin (observed on both 2D-CEUS and 3D-CEUS) | 7 | Rough (observed on both 2D-CEUS and 3D-CEUS) | 3 | Without enhancement(CR) | | Observed on both 2D-CEUS and 3D-CEUS | 18 | Observed on 2D-CEUS alone (not definite determined on 3D-CEUS) | 5 |

CEUS: contrast-enhanced ultrasound; SOR: standard of reference; RT: residual tumor; CR: complete response.
