OBJECTIVE The purpose of this study was to report our initial experience in the assessment of liver trauma with real-time contrast-enhanced sonography (CES). METHODS From January 2000 to December 2003, there were 431 hemodynamically stable patients evaluated with sonography for blunt abdominal trauma. Among these patients, 87 were selected to undergo(More)
BACKGROUND Active contrast medium extravasation is a known angiographic and computed tomographic sign of ongoing, potentially life-threatening hemorrhage. Sonography (US) is frequently the first imaging option for screening patients with abdominal emergencies. Because of the current possibilities of low-mechanical-index, real-time, contrast-specific(More)
OBJECTIVE Low mechanical index contrast-specific sonography is a new technique that uses the harmonic capabilities of second-generation contrast agents to produce real-time contrast-enhanced gray-scale images. We describe the contrast-specific sonographic findings of pyogenic hepatic abscesses. CONCLUSION Contrast-specific sonography was used to assess(More)
OBJECTIVE The purpose of this study was to report and analyze a new contrast-enhanced ultrasonographic (CEUS) imaging finding, the transient hepatic echogenicity difference due to perfusion changes, using computed tomography (CT) as a reference standard. METHODS We retrospectively investigated the records of patients evaluated in a 2-year period,(More)
Cystic breast lesions with a nonsimple appearance, either complicated or complex, pose unique diagnostic difficulties, in part owing to their potentially malignant nature. Current ultrasound classification systems are based on morphostructural aspects only. The objective of this paper is to highlight the adjunctive role of Doppler techniques. Over a 1-year(More)
OBJECTIVE Sonography is being used with increasing frequency in the assessment of locoregional tumor spread in patients with melanoma. Nevertheless, to maximize its practical impact, sonography should be performed with state-of-the-art equipment, by specifically trained operators, and using a careful exploration technique and well-defined diagnostic(More)
Contrast-enhanced sonography (CEUS) has become a routine part of diagnostic imaging of the liver. Its possibilities, limitations, and indications have been defined in adequately large clinical series and in guidelines and recommendations. We prospectively evaluated physicians' orders for hepatic CEUS received in the radiology department of a large oncology(More)
