| 摘要 目的 比较超声造影（CEUS）与增强CT（CECT）在胆囊占位性病变中的增强特征、诊断效能及一致性。方法 分析48例胆囊占位性病变患者CEUS与CECT的增强特征，比较二者诊断的敏感性、特异性、准确率，阴性预测值、阳性预测值，及诊断的一致性检验Kappa值。结果 CEUS与CECT对胆囊占位性病变各增强特征比较，差异均无统计学意义（P＞0.05）。CEUS与CECT诊断胆囊病变的敏感性分别为94.74%（18/19）和89.47%（17/19）（P=0.895），特异性分别为90.48%（19/21）和95.24%（20/21）（P=0.905），准确率分别为92.50%（37/40）和92.50%（37/40）（P=1.000），阳性预测值分别为90.0%（18/20）和94.44%（17/8），阴性预测值分别为95.0%（19/20）和90.91%（20/22）。CEUS、CECT与病理结果一致性检验Kappa值分别为0.850、0.849，二者之间诊断结果一致性检验 Kappa值为0.900。结论 CEUS与CECT对胆囊占位性病变的增强特征相似，二者诊断结果一致性良好且均具有较高的诊断效能。 |

| Abstract: |
| Objective To compare the contrast characteristics, diagnostic efficacy and consistency of contrast-enhanced ultrasound (CEUS) and enhanced CT (CECT) in the diagnosis of gallbladder space-occupying lesions. Methods Forty-eight patients with gallbladder space-occupying lesions were confirmed by operation and pathology. The enhancement characteristics of CEUS and CECT in 48 patients with gallbladder space-occupying lesions were analyzed. The sensitivity, specificity, accuracy, negative and positive predictive value of the two diagnoses were compared, and Kappa value of the consistency test were calculated. Results There was no significant difference in the enhanced characteristics of CEUS and CECT in gallbladder space-occupying lesions (P>0.05). The sensitivity of CEUS and CECT in the diagnosis of gallbladder lesions were 94.74% (18/19) and 89.47% (17/19) (P=0.895), respectively, and the specificities were 90.48% (19/21) and 95.24% (20/21) (P=0.905) , respectively, the accuracy was 92.50% (37/40) and 92.50% (37/40)（(P=1.00）, respectively, and the positive predictive values were 90.0% (18/20) and 94.44% (17/8), respectively，the negative predictive values were 95.0% (19/20) and 90.91% (20/22), respectively. Both CEUS and CECT were in good agreement with postoperative pathological findings (Kappa values were 0.850, 0.849, respectively), and the results of the two examinations were consistent (Kappa value = 0.900). Conclusion CEUS and CECT have similar features for the enhancement of gallbladder space-occupying lesions. The diagnostic results are consistent, and they all have high diagnostic efficacy. |
