摘要

目的：

探讨原发性小肝癌(SHCC)的超声造影与彩色多普勒超声特征表现，分析两者的临床诊断价值。

方法：

选择80个经影像学检查和细胞学穿刺或手术病理确诊的原发性SHCC病灶(最长径3 cm)，回顾性分析其超声造影与彩色多普勒超声特征。

结果：

超声造影显示54个病灶呈整体弥漫性快进快出式增强特点；18个病灶造影剂消退缓慢，呈快进慢出式特点；8个病灶呈慢进快出式特点。灵敏度为97.4%(75/77)，特异度为94.6%(70/74)，准确率为93.8%(75/80)。彩色多普勒超声显示76个病灶血供为Ⅰ~Ⅱ级血管，收缩期峰值血流速度(PSV)为(5011.9)cm/s，阻力指数(RI)为0.700.10；4个病灶因位置深而血流显示不理想。灵敏度为91.7%(66/72)，特异度为83.8%(57/68)，准确率为77.5%(62/80)。两者均能较好反映原发性SHCC的血流灌注特征，超声造影较彩色多普勒超声更能敏感地动态显示原发性SHCC的血流动力学特点。

结论：

超声造影和彩色多普勒超声均可较敏感地预测原发性SHCC，具有重要意义和应用价值。

Abstract

Objective:

To evaluate the value of contrast-enhanced ultrasound (CEUS) and color Doppler ultrasound in the iagnosis of primary small hepatocellular carcinoma (SHCC).

Methods:

A total of 80 primary SHCCS (diameter less than 3 cm) confirmed by imaging

cytological biopsy or surgical pathology were selected. The features of CEUS and color Doppler ultrasound were retrospectively analyzed.

Results:

On CEUS 54 lesions displayed fast in fast out pattern

16 lesions subsided slowly as fast in slow out pattern

and 8 lesions displayed slow in fast out pattern.

The sensitivity was 97.4% (75/77)

the specificity was 94.6% (70/74)

and the accuracy was 93.8% (75/80). Color Doppler ultrasound showed that 76 lesions had blood supply vessels withⅠ-Ⅱ grade. The peak systolic velocity (PSV) was (5011.9) cm/s

and resistance index (RI) was 0.70 0.10. Four lesions had unsatisfactory imaging because of deep position. The sensitivity was 91.7% (66/72)

the specificity was 83.8% (57/68)

and the accuracy was 77.5% (62/80). The two diagnostic methods could effectively display perfusion characteristics of primary SHCC.

Conclusion:

CEUS and color Doppler ultrasound can effectively predict primary SHCC

with significance and application value in clinic.
