摘要

目的：

比较1 cm肝细胞癌（hepatocellular carcinoma，HCC）的超声造影与动态对比增强磁共振成像（dynamic contrast-enhanced magnetic resonance imaging，DCE-MRI）各时相的表现。

方法：

分析比较53例经术后病理学检查证实的1 cm单发HCC病灶的超声造影图像及DCE-MRI的时相变化（动脉期、门脉期、延迟期）。

结果：

在53例确诊单发的1 cm HCC病灶中，100.0%（53/53）病灶在超声造影以及DCE-MRI中均表现有不同程度增强。在门脉期，47.17%（25/53）病灶超声造影及DCE-MRI均表现为低回声，22.64%（12/53）均表现为高或等回声；在延迟期，62.26%（33/53）病灶超声造影及DCE-MRI均表现为低回声，7.55%（4/53）均表现为持续增强。对于1 cm HCC，超声造影及DCE-MRI在整个造影过程中减退表现完全一致的有54.72%（29/53）。两种影像学方法对于1 cm HCC病灶动脉期增强、门脉延迟期减退的表现差异无统计学意义。

结论：

超声造影及DCE-MRI在诊断1 cm HCC时减退变化一致，两种方法均能反映1 cmHCC的血流动力学表现特点。

Abstract

Objective:

To compare the image findings of contrast-enhanced ultrasound and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in 1 cm hepatocellular carcinoma (HCC).

Methods:

To analyze and compare the phase changes (arterial phase

portal phase and delayed phase) of contrast-enhanced ultrasound and DCE-MRI for 53 cases of 1 cm HCC lesions confirmed by postoperative pathology.

Results:

All of the 53 lesions (53

/53) confirmed of single 1 cm HCC had showed different degrees of enhancement in contrast-enhanced ultrasound and DCE-MRI. And 47.17% (25/53) had showed hypo-enhanced on both two methods in portal phase

while 22.64% (12/53) had showed hyper-enhanced or iso-enhanced. In the late phase

62.26% (33/53) had showed hypo-echoic/iso-intensity

and 7.55% (4/53) had presented as persistent enhancement on both two methods. 54.72% (29/53) of the patients with 1 cm HCC had showed the same dynamic enhancement and washout process during the whole process. The difference between the two imaging methods in the phase changes of portal phase and late phase was not statistically significant.

Conclusion:

Contrast-enhanced ultrasound and DCE-MRI have the same phase changes in the diagnosis of 1 cm HCC

and both methods can reflect the hemodynamic characteristics of 1 cm HCC.
