摘要
目的分析胆囊占位性病变的超声造影与增强CT图像特征,探讨二者的临床诊断价值。方法分析48例胆囊占位性病变患者的超声造影与增强CT图像特征,比较两种方法诊断胆囊占位性病变的敏感性、特异性、准确率。结果超声造影图像特征比较:增强早期增强水平、病灶基底情况、胆囊壁的完整性在胆囊良恶性病变中比较差异均有统计学意义(均P<0.05);增强CT图像特征比较:静脉期增强水平、增强形态、病灶基底情况、胆囊壁的完整性在胆囊良恶性病变中比较差异均有统计学意义(均P<0.05)。超声造影与增强CT诊断胆囊占位性病变的敏感性、特异性、准确率、阳性预测值、阴性预测值分别为94.74%、90.48%、92.50%、90.00%、95.00%和89.47%、95.24%、92.50%、94.44%、90.91%。结论超声造影与增强CT在胆囊占位性病变的鉴别诊断中均有较高价值。
Objective To analyze the characteristics of contrast-enhanced ultrasonography(CEUS)and enhanced CT(CECT)of gallbladder space-occupying lesions,and to explore the clinical diagnostic value. Methods Forty-eight patients with gallbladder space-occupying lesions were confirmed by operation and pathology. The enhancement characteristics of CEUS and CECT in the 48 patients were analyzed.The sensitivity,specificity,accuracy,negative and positive predictive value of the two methods were compared. Results Comparison of CEUS images showed the differences of the enhancement pattern in the early stage,lesion basement,and the integrity of gallbladder wall were statistically significant between benign and malignant gallbladder lesions(all P<0.05).Comparison of CECT images showed that the differences of enhancement in venous phase,enhancement morphology,lesion basement,and gallbladder wall integrity were statistically significant between benign and malignant gallbladder lesions(all P<0.05).The sensitivity of CEUS and CECT in the diagnosis of gallbladder space-occupying lesions were 94.74% and 89.47%,the specificity were 90.48% and 95.24%,the accuracy were 92.50% and 92.50%,the positive predictive value were 90.0% and 94.44%,and the negative predictive value were 95.0.% and 90.91%,respectively.Conclusion CEUS and CECT both have high diagnostic value in the differential diagnosis of gallbladder space-occupying lesions.
