To evaluate the use of contrast-enhanced ultrasonography (CEUS) in patients with blunt abdominal trauma.
A total of 133 hemodynamically stable patients were evaluated using ultrasonography (US), CEUS and multislice Computer Tomography (CT) da eliminare.
In 133 patients, CT identified 84 lesions: 48 cases of splenic injury, 21 of liver injury, 13 of kidney or adrenal gland injury and 2 of pancreatic injury. US identified free fluid or parenchymal abnormalities in 59/84 patients positive at CT and free fluid in 20/49 patients negative at CT. CEUS revealed 81/84 traumatic injuries identified at CT and ruled out traumatic injuries in 48/49 negative at CT. Sensitivity, specificity, positive and negative predictive values for US were 70.2%, 59.2%, 74.7% and 53.7%, respectively; for CEUS the values were 96.4%, 98%, 98.8% and 94.1%, respectively.
The study showed that CEUS is more accurate than US and nearly as accurate as CT, and CEUS can therefore be proposed for the initial evaluation of patients with blunt abdominal trauma.
评估超声造影（CEUS）在钝性腹部创伤患者中的应用。
共对133例血流动力学稳定的患者进行了超声检查（US）、CEUS和多层计算机断层扫描（CT，待删除）。
在133例患者中，CT发现84处损伤：脾损伤48例，肝损伤21例，肾或肾上腺损伤13例，胰腺损伤2例。US在CT检查阳性的84例患者中的59例发现了游离液体或实质异常，在CT检查阴性的49例患者中的20例发现了游离液体。CEUS显示了CT检查发现的84处创伤性损伤中的81处，并排除了CT检查阴性的49例中的48例创伤性损伤。US的敏感性、特异性、阳性和阴性预测值分别为70.2%、59.2%、74.7%和53.7%；CEUS的相应值分别为96.4%、98%、98.8%和94.1%。
该研究表明，CEUS比US更准确，且与CT几乎一样准确，因此可以推荐CEUS用于钝性腹部创伤患者的初步评估。
