Greyscale and contrast enhanced ultrasonography for characterization of gastric malignant tumors.

Aims: To evaluate the utility of grey scale ultrasonography (US) and contrast enhanced ultrasonography (CEUS) for characterization of malignant gastric tumors.

Material And Methods: The study was conducted prospectively and it included a number of 30 patients with malignant gastric tumors diagnosed through upper tract endoscopy and biopsy: 25 adenocarcinomas, 3 lymphomas, and 2 stromal tumors. All the patients were examined by US, followed immediately by CEUS, using both oral and intravenous contrast agents.

Oral and I.V. contrast enhanced ultrasonography of the digestive tract--a useful completion of the B-mode examination: a literature review and an exhaustive illustration through images.

Contrast enhanced ultrasonography, using i.v. and/or oral/rectal contrast agents, represents a technical development of the US method, which has proved its applicability in the qualitative and quantitative assessment of the normal and pathological circulatory bed, as well as of the digestive lumen.

The role of i.v. and oral contrast enhanced ultrasonography in the characterization of gastric tumors. A preliminary study.

Objective: To identify the diagnosis benefits of harmonics optimized i.v. contrast enhanced ultrasonography (CEUS) in the detection and characterization of several gastric neoplasms.
