We developed prototype real-time 3-D intracardiac echocardiography catheters with integrated micromotors, allowing internal oscillation of a low-profile 64-element, 6.2-MHz phased-array transducer in the elevation direction. Components were designed…

Audiograms in air and underwater, determined by previous workers for four pinniped species, two eared seals '(Otariidae) and two phocids (Phocidae), are supplemented here by measurements on their middle ear ossicular mass, enabling mechanistic…

Objectives-The purpose of this study was to determine whether the elasticity imaging/B-mode ratio on strain elastography can predict breast cancer tumor grades. Methods-A retrospective review of patients with breast lesions who underwent strain…

Objective. Both sonography and scintigraphy have been used to evaluate gallbladder function with the use of sincalide (cholecystokinin [CCK]). However, the reported ejection fractions (EFs) for the two modalities are not the same. The techniques…

Objectives-The purpose of this study was to determine the sensitivity and specificity of real-time compression elasticity imaging in characterizing breast lesions as benign or malignant. Methods-A cohort of 578 women scheduled for sonographically…

Breast elastography is a new sonographic technique that provides additional characterization information on breast lesions over conventional sonography and mammography. This technique provides information on the strain or hardness of a lesion,…

Objective. The purpose of this study was to determine the accuracy of prenatal cardiac diagnosis, prognosis, and outcome of totally anomalous pulmonary venous connection (TAPVC) and to determine echocardiographic clues in the prenatal diagnosis of…

An aortopulmonary septal defect is a rare cardiac malformation in which there is a communication between the ascending aorta and pulmonary trunk in the presence of 2 separate semilunar valves. There are reports of postnatal diagnosis of…

Tetralogy of Fallot is known to be associated with anomalies in the origin or course of coronary arteries. We describe a case of fetal echocardiographic diagnosis at 24 weeks' gestation of tetralogy of Fallot with a single right coronary artery in…

We describe the prenatal diagnosis of partial anomalous pulmonary venous connection (PAPVC) at 27 weeks' gestation in a patient with Fryns with the right upper pulmonary vein to the right superior vena cava and right atrial junction. The remaining…

Isolation of the subclavian artery is an uncommon anomaly of the aortic arch system in which one subclavian artery loses its connection with the aorta and arises from the homolateral pulmonary artery by way of a ductus arteriosus. An isolated…

Objective. The purpose of this series was to describe the fetal echocardiographic findings in hypoplastic left heart syndrome with aortic atresia and ventriculocoronary arterial communication and implications of these findings. Methods. We describe 2…

Objective. The purpose of this series is to describe the prenatal echocardiographic findings of vascular rings. Methods. The 3-vessel and trachea view consists of the axial view of the upper mediastinum. The normal left aortic arch appears as a…

Prenatal diagnosis of partial anomalous pulmonary venous connection (PAPVC) is rare. We describe a case in which the diagnosis was made at 24 weeks' gestation. The fetus had a double-outlet right ventricle, mitral atresia, a subaortic ventricular…

Bats are among the most gregarious and vocal mammals, with some species demonstrating a diverse repertoire of syllables under a variety of behavioral contexts. Despite extensive characterization of big brown bat (Eptesicus fuscus) biosonar signals,…

Adult mice are highly vocal animals, with both males and females vocalizing in same sex and cross sex social encounters. Mouse pups are also highly vocal, producing isolation vocalizations when they are cold or removed from the nest. This study…
