探讨和比较CT与彩色多普勒超声在急性胰腺炎（AP）合并脂肪肝诊断中的临床价值。

纳入2020年1月至2021年12月于东南大学附属中大医院溧水分院就诊的疑似AP合并脂肪肝患者80例，所有患者均行CT检查和彩色多普勒超声影像检查，记录患者两种检查方法的影像特征。计算两种检查方法对诊断AP患者的准确性、特异度和灵敏度。记录两种检查方法对诊断脂肪肝的分级情况。

结合患者的临床表现、血清淀粉酶活性、脂肪酶活性和影像学表现，80例疑似病例中共76名确诊为AP。CT检查结果显示，共73例患者呈现AP的典型影像特征，诊断AP的准确度为93.75%，特异度为75.00%，灵敏度为94.74%；彩色多普勒超声检查结果显示，共70例患者呈现AP的超声影像特征，诊断AP的准确度为87.50%，特异度为50.00%，灵敏度为89.47%。两种检查的准确度、特异度和灵敏度差异均无统计学意义（P>0.05）。在诊断脂肪肝方面，CT检查结果显示，68例患者（85.00%）呈现脂肪肝的典型影像特征，发现轻度脂肪肝25例（31.25%），中度脂肪肝30例（37.50%），重度脂肪肝13例（16.25%）。彩色多普勒超声检查结果显示，64例患者（80.00%）呈现脂肪肝的超声影像特征，其中轻度脂肪肝24例（30.00%），中度脂肪肝28例（35.00%），重度脂肪肝12例（15.00%）。两种影像学方法在诊断脂肪肝中无明显差异（P>0.05）。

CT和彩色多普勒超声诊断AP合并脂肪肝患者均可获得较高准确性，两种方法的诊断效果无显著差异，在临床应用过程可结合患者实际情况来选择合适的影像检查方法。

To explore and compare the clinical value of CT and color Doppler ultrasound in the diagnosis of acute pancreatitis (AP) complicated with fatty liver disease (FLD).

A total of 80 patients suspected of AP complicated with FLD who were admitted to zhongda Hospital Lishui Branch Affiliated to Southeast University from January 2020 to December 2021 were included. All patients underwent CT examination and color Doppler ultrasound imaging examination, and the imaging characteristics of the two examination methods were recorded. The accuracy, specificity, and sensitivity of the two examination methods in diagnosing AP patients were calculated. The grading of the two examination methods in diagnosing FLD was recorded.

Combined with the patient's clinical manifestations, serum amylase activity, lipase activity, and imaging manifestations, 76 of the 80 suspected cases were diagnosed with AP. CT examination results showed that 73 patients presented typical imaging features of AP, with an accuracy of 93.75%, specificity of 75.00%, and sensitivity of 94.74%; color Doppler ultrasound examination results showed that 70 patients presented ultrasound imaging features of AP, with an accuracy of 87.50%, specificity of 50.00%, and sensitivity of 89.47%. There was no statistically significant difference in accuracy, specificity, and sensitivity between the two groups (P>0.05). In the diagnosis of FLD, CT examination results showed that 68 patients (85.00%) presented typical imaging features of FLD, with 25 cases (31.25%) of mild FLD, 30 cases (37.50%) of moderate FLD, and 13 cases (16.25%) of severe FLD. Color Doppler ultrasound examination results showed that 64 patients (80.00%) presented ultrasound imaging features of FLD, with 24 cases (30.00%) of mild FLD, 28 cases (35.00%) of moderate FLD, and 12 cases (15.00%) of severe FLD. There was no statistically significant difference between the two imaging methods in diagnosing FLD (P>0.05).

Both CT and color Doppler ultrasound can obtain high accuracy in diagnosing AP complicated with FLD, and there is no statistically significant difference in the diagnostic effects of the two methods. In clinical application, the appropriate imaging examination method can be selected according to the actual situation of the patient.
