The aim of the present study was to evaluate acute blunt pancreatic injury using contrast-enhanced ultrasonography (CEUS) in comparison with contrast-enhanced computed tomography (CECT). Superficial and deep lesions were established by blunt pancreatic injury in 40 Chinese Guangxi Bama miniature pigs. Conventional ultrasound (US), CEUS and CECT were performed to detect traumatic lesions in the pancreas. A total of 40 lesions were established, including 20 deep lesions and 20 superficial lesions. US identified 21 of the 40 lesions, including 7 of the 20 superficial and 14 of the 20 deep lesions. CEUS identified 34 of the 40 lesions, including 14 of the 20 superficial and 20 of the 20 deep lesions. CECT identified 33 of the 40 lesions, including 13 of the 20 superficial and 20 of the 20 deep lesions. The detection rate of acute blunt pancreatic injury using CEUS was significantly higher compared with that using US (85 vs. 52.5%, P<0.05), however there was no significant difference in the detection rate of pancreatic lesions between CEUS and CECT (85 vs. 82.5%, P>0.05). CEUS improves the diagnostic levels of conventional US and is comparable with CECT scans in the diagnosis of blunt pancreatic injury.
本研究旨在对比增强超声（CEUS）与对比增强计算机断层扫描（CECT）在评估急性钝性胰腺损伤中的应用。通过对40只中国广西巴马小型猪进行钝性胰腺损伤，建立浅表和深部损伤模型。采用常规超声（US）、CEUS和CECT检测胰腺创伤性损伤。共建立了40处损伤，包括20处深部损伤和20处浅表损伤。US识别出40处损伤中的21处，包括20处浅表损伤中的7处和20处深部损伤中的14处。CEUS识别出40处损伤中的34处，包括20处浅表损伤中的14处和20处深部损伤中的20处。CECT识别出40处损伤中的33处，包括20处浅表损伤中的13处和20处深部损伤中的20处。与US相比，CEUS对急性钝性胰腺损伤的检出率显著更高（85%对52.5%，P<0.05），然而CEUS与CECT在胰腺损伤检出率上无显著差异（85%对82.5%，P>0.05）。CEUS提高了常规US的诊断水平，在钝性胰腺损伤诊断中与CECT扫描相当。
