Abstract: Background: Medical imaging techniques are important for patients with liver disease. An unenhanced ultrasound examination recognizes the normal from the abnormal liver that may require further examination. One crucial variable in selecting an imaging modality test is the capacity to give a quick finding. Choices for extra imaging modalities incorporate Computed Tomography (CT), which requires breath holding that sometimes be contraindicated.
Objective: To compare clinical effectiveness of using contrast-enhanced ultrasound (CEUS) for assessment of adults with focal liver lesions, with that of computed tomography (CT) in patients those had non-conclusive previous studies.
Method: Systemic review for previous studies through databases, including MEDLINE (PubMed), EMBASE, Cochrane of Systematic Reviews and database of Abstracts of Reviews. Search was performed for studies published up to 2015. Studies were selected depending on evaluation of the effectiveness of contrast enhanced US in comparison with CT in assessment of different focal liver lesions.
Results: Ultrasound (US) is frequently the first-line imaging modality for liver study. It is operator dependent. Some of the drawbacks are degradation of the images especially in obese patients. Regular considerate lesions, for example hemangiomas are normally have a trademark appearance on US, frequently preclude other assessment in non-oncology patients.
Lately, with the presence of microbubble technique, which is a dynamic imaging that develops rapidly, Contrast Enhanced US (CEUS), offers the novel capacity to perform constant, continuous evaluation of typical hepatic parenchyma, hepatic vessels and liver lesions.
Conclusion: Contrast-enhanced ultrasound using a low mechanical index is the modality of choice for detection of liver malignancy. In this study showed that contrast-enhanced ultrasound imaging is highly accurate in characterizing malignant and benign focal liver lesions, than CT and is considered safer than CT.
Keywords: Contrast enhanced US, CT scan, liver lesions.
