【摘要】：目的探讨超声及声触诊组织量化技术(VTQ)在肝囊肿与囊性肝包虫诊断中的应用价值。方法选择48例均进行了常规超声检查的患者,被纳入研究范围:肝脏囊性局灶病变直径3cm和深度在4~8cm之间。48例经手术切除或穿刺活检病理证实的肝囊肿及囊型肝包虫,应用超声成像技术检查获得囊肿的声像图特征并采用VTQ检测囊内容物的剪切波速度(Vs)。对每一患者,在触摸组织量化区进行5次测量得到的结果,区分单纯囊肿和肝包虫囊肿。判读方法:5次测量至少有2次获得数值者诊断为肝包虫囊肿;5次测量均为无值者诊断为肝囊肿。结果敏感性、特异性、阳性预测值、阴性预测值和准确性分别为86.7%、83.3%、89.7%、78.9%和85.4%。结论超声及VTQ在肝囊性病变的鉴别诊断中有重要的价值。
[Abstract]:Objective to evaluate the value of ultrasound and acoustic palpation tissue quantification (VTQ) in the diagnosis of hepatic cyst and cystic hepatic hydatid. Methods Forty-eight patients who underwent conventional ultrasound examination were included in the study. The diameter and depth of hepatic cystic lesions were between 3cm and 4~8cm. 48 cases of hepatic cyst and cystic hepatic hydatid were confirmed by surgical resection or biopsy. Ultrasonic imaging technique was used to examine the sonographic features of cysts and VTQ was used to detect the shear wave velocity (Vs). Of the cyst contents. For each patient, the results were measured five times in the touch tissue quantification area to distinguish simple cysts from hepatic hydatid cysts. Interpretation method: at least 2 times of the 5 measurements were diagnosed as hepatic hydatid cysts, and the 5 times of measurement were all of no value in the diagnosis of hepatic cysts. Results sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 86.7% and 83.3%, 88.7% and 85.4%, respectively. Conclusion Ultrasound and VTQ have important value in differential diagnosis of hepatic cystic disease.
