【摘要】 目的 探讨微血流成像(MFI)与超声造影(CEUS)在良性与恶性胆囊息肉样病变(PLG)鉴别诊断中的应用。方法 收集98例PLG患者作为研究对象。以手术病理作为金标准，计算MFI与CEUS在鉴别诊断PLG中的灵敏度、特异度及准确度。结果 98例PLG患者中85例良性PLG,13例恶性PLG,良性PLG包括49例胆囊胆固醇息肉、26例胆囊腺肌症、10例胆囊腺瘤，恶性PLG包括13例胆囊癌。MFI诊断良性PLG 78例、恶性PLG 20例，鉴别诊断的灵敏度、特异度和准确度分别为69.23%(9/13)、87.06%(74/85)、84.69%(83/98)。CUES诊断良性PLG 79例、恶性PLG 19例，鉴别诊断的灵敏度、特异度和准确度分别为46.15%(6/13)、81.82%(72/85)、79.59%(78/98)。与CUES比，MFI鉴别诊断良性与恶性PLG的灵敏度、特异度和准确度均较高。结论 MFI与CEUS对良性与恶性PLG都有一定的鉴别诊断价值，MFI的诊断效能总体高于CEUS。更多还原

【Abstract】 Objective To explore the application of the microflow imaging(MFI) and contrast-enhanced ultrasound(CEUS) in the differential diagnosis of benign and malignant polypoid lesion of gallbladder(PLG). Methods 98 cases patients with PLG in our hospital were retrospectively analyzed. Using surgical and pathological results as the gold standard, the sensitivity, specificity and accuracy of PLG and CEUS in the differential diagnosis of benign and malignant PLG were calculated and compared. Results Among the 98 patients with PLG, 85 cases were benign PLG included 49 cases gallbladder polyps, 26 cases gallbladder carcinoma and 10 cases gallbladder adenomas. 13 cases were malignant PLG included 13 cases gallbladder cancers. In the MFI, the sensitivity, specificity and accuracy of the differential diagnosis of benign and malignant PLG were 69.23%(9/13), 87.06%(74/85) and 84.69%(83/98), respectively CUES diagnosed 79 cases of benign PLG and 19 cases of malignant PLG. The sensitivity, specificity and accuracy of the differential diagnosis were 46.15%(6/13), 81.82%(72/85) and 79.59%(78/98), respectively. Compared with CEUS, MFI had higher sensitivity, specificity and accuracy in the differential diagnosis of benign and malignant PLG. Conclusions Both MFI and CEUS have a certain application value in the differential diagnosis of benign and malignant PLG, and the diagnostic efficacy of MFI is generally higher than that of CEUS.更多还原
