Initially, a set of guidelines for the use of ultrasound contrast agents was published in 2004 dealing only with liver applications. A second edition of the guidelines in 2008 reflected changes in the available contrast agents and updated the guidelines for the liver, as well as implementing some non-liver applications. Time has moved on, and the need for(More)
OBJECTIVE The objective of this presentation is to provide an overview of sonographic manifestations of Budd-Chiari syndrome (BCS). METHODS Patients were scanned with ultrasound systems using mainly a 2- to 5-MHz curvilinear transducer and in some patients a 5- to 12-MHz linear transducer. The patients were asked to fast from the previous night or for at(More)
OBJECTIVE To determine the value of the filarial dance sign as a diagnostic sign of scrotal filarial infection and to recognize unsuspected scrotal filariasis by this sign. METHODS Eight symptomatic patients in whom the filarial dance sign was shown on high-resolution ultrasonography were studied, investigated, and followed after treatment with(More)
Cloacal malformation is a rare abnormality, characterized by direct communication between the gastrointestinal, urinary, and genital structures, resulting in a single perineal opening. Prenatal diagnosis is difficult because of nonvisualization of the communication. We report a case of prenatal diagnosis of this condition, in which the recognition of(More)
OBJECTIVES In children with urinary tract infection, the incidence of vesicoureteral reflux (VUR) is nearly 30% to 40%. The standard for the diagnosis of VUR is voiding cystourethrography (VCUG). This study assessed the role of color flow Doppler sonography (CFDS) in the diagnosis of VUR and ureteral jets. METHODS CFDS imaging was performed in 36 patients(More)
Idiopathic arterial calcification of infancy, or occlusive infantile arterial calcification, is a rare cause of arterial calcification. This condition is inherited as an autosomal recessive pattern, which is almost always fatal. In most of the 100 cases described in the literature, the diagnosis was made at autopsy; a few cases have been reported in which(More)
Juvenile polyposis is an uncommon condition characterized by development of multiple juvenile polyps, predominantly in the colon but also in the rest of the gastrointestinal tract. The condition usually appears in childhood. The rarer and often fatal form, occurring in infancy, is typified by diarrhea, protein-losing enteropathy, bleeding, and rectal(More)
PURPOSE To evaluate the use of color Doppler sonography in the diagnosis of thoracic outlet syndrome. METHODS We studied color Doppler sonographic findings in 5 clinically suspected cases of thoracic outlet syndrome. The subclavian artery and vein were studied in varying degrees of abduction to assess the severity of the syndrome. RESULTS Significant(More)
