【摘要】：目的探讨声脉冲辐射力成像技术(ARFI)在鉴别肝血管瘤与肝内小转移癌的应用价值。方法采用ARFI对29个肝血管瘤及26个肝转移癌(直径小于或等于3cm,肝内病灶小于或等于2个)进行声触诊组织成像(VTI)及声触诊组织定量(VTQ)检测,获取VTI弹性图和病灶及背景肝组织的剪切波速度(SWV)值,并对其进行分析。结果 VTI弹性图中,26个肝转移癌病灶边界清晰度优于常规超声13个(50.00%),肝血管瘤为5个(17.24%),差异有统计学意义(P=0.004);肝转移癌组病灶范围大于常规超声18个(69.23%),肝血管瘤组7个(24.14%),二者比较差异有统计学意义(P=0.001)。21个(80.77%)肝转移癌呈灰黑色,8个(27.59%)肝血管瘤呈灰黑色;肝转移癌SWV[(2.83±1.20)m/s]明显高于血管瘤SWV[(1.49±0.41)m/s],二者比较差异有统计学意义(P0.01)。血管瘤组的肝组织SWV与肝转移癌组肝组织SWV比较差异无统计学意义(P=0.16)。结论 ARFI有望成为一种新的鉴别肝血管瘤与肝转移癌的无创性检查方法。
[Abstract]:Objective to evaluate the value of acoustic pulse radiography (ARFI) in differentiating hepatic hemangioma from intrahepatic small metastatic carcinoma. Methods ARFI was used to detect 29 hepatic hemangiomas and 26 liver metastases (diameter less than or equal to 3 cm, intrahepatic lesions less than or equal to 2) by acoustic palpation tissue imaging (VTI) and acoustic palpation tissue quantitative analysis (VTQs). The shear wave velocities and shear wave velocities of the lesions and background liver tissues were obtained and analyzed. Results in VTI elastogram, the boundary clarity of 26 liver metastases was better than that of conventional ultrasound, and that of hepatic hemangioma was 17. 24%, the difference was statistically significant (P < 0. 004), the range of lesions in metastatic liver cancer group was larger than that in normal ultrasound group, and in hepatic hemangioma group, the lesion area was larger than that in normal ultrasound group, and in hepatic hemangioma group, the area of lesion was larger than that in normal ultrasound group. The difference between the two groups was statistically significant (P < 0.01). 21 cases of liver metastasis were gray black, and 8 cases of hepatic hemangioma were gray black. The SWV of metastatic liver cancer [2.83 卤1.20)m/s] was significantly higher than that of hemangioma SWV [1.49 卤0.41)m/s], and the difference was statistically significant (P 0.01). There was no significant difference in liver tissue SWV between hemangioma group and hepatic metastatic carcinoma group (P < 0. 16). Conclusion ARFI may be a new non-invasive method for differentiating hepatic hemangioma from metastatic carcinoma.
