摘要

目的：

比较超声造影(CEUS)与增强CT(CECT)显示脾实质性肿瘤的血流灌注特点。

方法：

对21例脾实质性肿瘤(血管瘤5例、血管淋巴管瘤5例、淋巴瘤4例、转移性肿瘤7例)分别进行CEUS和CECT检查，比较两种影像学检查技术的增强表现。

结果：

CEUS和CECT对脾病灶内部的血流显示率均为100%，对病灶内部血流灌注的敏感程度均优于彩色多普勒(71.4%)(

＜0.05)。CEUS和CECT反映的脾脏病变增强方式完全一致。CEUS对增强过程中特殊表现(树枝状、结节状和筛孔状增强)的检出率为57.1%(12/21)，与CECT相比，病灶血流灌注的增强表现更多样化，两者比较差异有统计学意义(

＜0.05)。

结论：

CEUS和CECT能敏感地显示脾实质性病变的血流动力学特点，有助于脾肿瘤的鉴别。

Abstract

Objective:

To compare the enhancement features of splenic solid tumors on contrast-enhanced ultrasonography (CEUS) and contrast-enhanced CT (CECT).

Methods:

Twenty-one patients with focal splenic lesions were enrolled

including 5 cases of hemangioma

5 cases of lympho-hemangioma

4 cases of lymphoma and 7 cases of metastases. Their enhancement appearances were compared.

Results:

The vascular displaying rates of CEUS and CECT were both 100%. The two contrast methods were more sensitive than color Doppler ultrasound in displaying the perfusion of the splenic lesions (71.4%) (

0.05). Hemodynamic characteristics of the splenic lesions were accordant. The

detection rate of special performance of CEUS was 57.1% (12/21) in the enhancement process. Compared to that of CECT

the enhancement on CEUS was more diversified. The difference was statistically significant between CEUS and CECT images (

0.05).

Conclusion:

Both CEUS and CECT can demonstrate hemodynamic features of splenic tumors sensitively

which is helpful in differential diagnosis of splenic tumors.
