“…In the high-energy trauma the use of US as first line diagnostic is superfluous and damaging and the use of CT without and with i.v.c onstrast material is imperative. In order to reduce the radiation dose, particularly in young people or children, CEUS has an important role in the follow-up of conservatively treated traumatic injuries of the abdominal parenchymatous organs (liver, spleen and kidneys) diagnosed by CT [39,40]. …”

In the assessment of polytrauma patient, an accurate diagnostic study protocol with high sensitivity and specificity is necessary. Computed Tomography (CT) is the standard reference in the emergency for evaluating the patients with abdominal trauma. Ultrasonography (US) has a high sensitivity in detecting free fluid in the peritoneum, but it does not show as much sensitivity for traumatic parenchymal lesions. The use of Contrast-Enhanced Ultrasound (CEUS) improves the accuracy of the method in the diagnosis and assessment of the extent of parenchymal lesions. Although the CEUS is not feasible as a method of first level in the diagnosis and management of the polytrauma patient, it can be used in the follow-up of traumatic injuries of abdominal parenchymal organs (liver, spleen and kidneys), especially in young people or children.

“…Development of multidetector helical CT (MDCT) ensured that dynamic CT could be used to evaluate the hemodynamics of hepatic masses and that triple‐phase helical CT could be used to rapidly scan the whole abdomen in three phases. In triple‐phase helical CT, a single bolus injection facilitates imaging during the phase of preferential arterial enhancement, that is, the arterial phase, followed by the portal venous phase and delayed phase . In humans, previous studies have shown that triple‐phase helical CT improves the detection of various hepatic masses .…”

The purpose of this study was to determine the utility of triple-phase helical computed tomography (CT) for differentiating canine hepatic masses. Seventy dogs with hepatic masses underwent triple-phase CT followed by surgical removal of the hepatic masses. Triple-phase helical CT scans for each dog included precontrast, arterial phase, portal venous phase, and delayed phase studies. The removed hepatic masses were histopathologically classified as hepatocellular carcinoma (n = 47), nodular hyperplasia (n = 14), and hepatic metastatic tumors (n = 9) in dogs. Of the 47 hepatocellular carcinomas, the most common CT findings included a heterogeneous pattern with hyper-, iso-, and hypoenhancement in both the arterial and portal venous phases (40/47, 85.1%). Of the 14 nodular hyperplasias, the most common CT findings were a homogeneous pattern with hyper- and isoenhancement in both the portal venous and delayed phases (13/14, 92.9%). Of nine hepatic metastatic tumors, the most common CT findings included a homogeneous hypoenhancement pattern in both the arterial and portal venous phases (8/9, 88.9%). In addition, 5 (55.6%) showed homogeneous hypoenhancement patterns in the delayed phase. Findings from our study indicated that triple-phase CT is a useful tool for preoperative differentiation of hepatocellular carcinoma, nodular hyperplasia, and hepatic metastatic tumors in dogs.

“…Acquisition of true nonenhanced images (TNE) could therefore be avoided, thereby reducing radiation dose to the patient. This is particularly important in multiphasic protocols for liver imaging [11,12], especially during follow-up and in young patients.…”

“…In tal modo sarebbe possibile evitare l'acquisizione d'immagini pre-contrastografiche reali (PCR) riducendo quindi la dose di radiazioni somministrata al paziente; tale aspetto riveste una particolare importanza nei protocolli di studio multifasici del fegato [11,12], specialmente in corso di follow-up e nei soggetti giovani.…”
