AbstractAbdominal contrast enhanced ultrasound (CEUS) is a relatively new investigation method that combines conventional ultrasound with a small amount of intravenous contrast through a peripheral vein (usually the cubital vein). The contrast is made by very small gas microbubbles floating in a phospholipid suspension. The size of microbubbles are between 1-10 micrometers, being to large to go out of the vessels, but sufficiently small to stay into the capillaries, and this is the reason for they can be used as vascular tracers. So, it is possible to obtain images with microvessels inside of different organs in different vascular phases (arterial, portal, venous), images that are similar with the one obtained in CECT and CEMRI.The intravenous contrast used in CEUS eliminates trough the lungs, during expiration. These is the reason why the most important contraindication for using iv contrast is severe respiratory failure. Also, it is important that intravenous contrast is not allergenic, the percentage of allergic reaction being extremly small (0,001%).The most important advantages of CEUS are:• It can be safely used for the pacients that are allergic to intravenous contrast used in CECT and CEMRI;• It can be used in pacients with chronic kidney disease;Abdominal contrast enhanced ultrasound is used in day-to-day practice mainly for evaluation of hepatic lesions, but also for pancreatic, kidney, testis pathology, as well as for inflammatory bowel diseases.

Limited Scope

AbstractIn pediatric and adult populations, intravenous contrast-enhanced ultrasound (CEUS) remains off-label for imaging of organs other than the liver and heart. This limited scope inhibits potential benefits of the new modality from a more widespread utilization. Yet, CEUS is potentially useful for imaging small organs such as the thyroid gland, lymph nodes, testes, ovaries and uterus, with all having locations and vasculature favorable for this type of examination. In the adult population, the utility of CEUS has been demonstrated in a growing number of studies for the evaluation of these small organs. The aim of this article is to present a review of pediatric CEUS of the thyroid gland, lymph nodes, testes, ovaries and uterus as well as to draw from the adult literature indications for possible applications in children.

Histopathological Result

Objectives: This study aimed to compare diagnostic efficiency for axillary sentinel lymph node (SLN) metastasis between lymphatic contrast-enhanced ultrasound (LCEUS) and intravenous contrast-enhanced ultrasound (ICEUS) in patients with breast cancer. We also examined whether adding ICEUS to LCEUS could improve the diagnostic accuracy of LCEUS. Methods: Sixty-nine patients with breast cancer were recruited preoperatively. All patients underwent LCEUS followed by ICEUS, and the enhancement pattern of one SLN was analysed for each patient. The targeted SLN was marked with wire and excised during surgery. The imaging diagnosis was compared with the histopathological result. Diagnostic efficiency was compared among LCEUS, ICEUS, and the combination of LCEUS and ICEUS. Results: The sensitivity values for LCEUS, ICEUS, and the combination of LCEUS and ICEUS were 86.2%, 82.6%, and 93.1%, respectively. Specificity values for the three methods were 95.0%, 92.5%, and 87.5%, respectively. Accuracy values for the three methods were 91.3%, 88.4%, and 89.9%, respectively. The area under the receiver operating characteristic (ROC) curve for LCEUS was 0.906, and there was no significant difference among LCEUS, ICEUS, and the combination of LCEUS and ICEUS (p = 0.752). Conclusions: LCEUS may represent an accurate method for predicting SLN metastasis preoperatively. Our findings suggest that adding ICEUS to LCEUS for SLN evaluation in patients with breast cancer is unnecessary. Advances in knowledge: This is the first study in which both LCEUS and ICEUS were performed for the same lymph node and the first to compare the diagnostic efficiency of LCEUS, ICEUS, and the combination of LCEUS + ICEUS.
