【摘要】：目的探討聲脈沖輻射力成像技術(shù)(ARFI)在鑒別肝血管瘤與肝內(nèi)小轉(zhuǎn)移癌的應(yīng)用價(jià)值。方法采用ARFI對(duì)29個(gè)肝血管瘤及26個(gè)肝轉(zhuǎn)移癌(直徑小于或等于3cm,肝內(nèi)病灶小于或等于2個(gè))進(jìn)行聲觸診組織成像(VTI)及聲觸診組織定量(VTQ)檢測(cè),獲取VTI彈性圖和病灶及背景肝組織的剪切波速度(SWV)值,并對(duì)其進(jìn)行分析。結(jié)果 VTI彈性圖中,26個(gè)肝轉(zhuǎn)移癌病灶邊界清晰度優(yōu)于常規(guī)超聲13個(gè)(50.00%),肝血管瘤為5個(gè)(17.24%),差異有統(tǒng)計(jì)學(xué)意義(P=0.004);肝轉(zhuǎn)移癌組病灶范圍大于常規(guī)超聲18個(gè)(69.23%),肝血管瘤組7個(gè)(24.14%),二者比較差異有統(tǒng)計(jì)學(xué)意義(P=0.001)。21個(gè)(80.77%)肝轉(zhuǎn)移癌呈灰黑色,8個(gè)(27.59%)肝血管瘤呈灰黑色;肝轉(zhuǎn)移癌SWV[(2.83±1.20)m/s]明顯高于血管瘤SWV[(1.49±0.41)m/s],二者比較差異有統(tǒng)計(jì)學(xué)意義(P0.01)。血管瘤組的肝組織SWV與肝轉(zhuǎn)移癌組肝組織SWV比較差異無(wú)統(tǒng)計(jì)學(xué)意義(P=0.16)。結(jié)論 ARFI有望成為一種新的鑒別肝血管瘤與肝轉(zhuǎn)移癌的無(wú)創(chuàng)性檢查方法。
[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 鹵1.20)m/s] was significantly higher than that of hemangioma SWV [1.49 鹵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.
