OBJECTIVE. We sought to compare image quality, contrast enhancement, and radiation dose in patients undergoing ECG-triggered high-pitch helical CT or non-ECG-synchronized helical CT of the thoracoabdominal aorta. MATERIALS AND METHODS. We…

Purpose: The objectives of the study were to evaluate the accuracy of the "bull's-eye" artifact of elasticity imaging (EI) in determining the benignity of cystic breast lesions and to determine the utility of such artifact in reducing the biopsy rate…

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,…

There is a large body of published material that supports the use of elastography, both strain and shear wave, for characterization of breast lesions. To a lesser extent, elastography can be used in the detection of breast abnormalities. This article…

Purpose: The objective of this study was to evaluate electronic beam steering to improve needle visualization. Methods: Various needles ranging from 27 to 12 gauge were evaluated with a modified CX50 (Philips Ultrasound, Bothell, Wash) using a 12-MHz…

With the recent FDA approval for characterization of focal liver lesions (FLL) in both pediatric and adult patients using Lumason (sulfur hexafluoride microbubbles), increased use of ultrasound contrast for routine clinical use is expected. This…

Purpose: To investigate the association of overall and disease-specific survival with the five standard treatment modalities for prostate cancer (CaP): radical prostatectomy (RP), brachytherapy (BT), external beam radiotherapy, androgen deprivation…

BackgroundFor most computer-aided diagnosis (CAD) problems involving prostate cancer detection via medical imaging data, the choice of classifier has been largely ad hoc, or been motivated by classifier comparison studies that have involved large…

To determine the feasibility of a prototype device combining 3D-automated breast ultrasound (ABVS) and digital breast tomosynthesis in a single device to detect and characterize breast lesions. In this prospective feasibility study, the FUSION-X-US…

OBJECTIVE. Sclerosing lobular hyperplasia is an infrequent benign lesion of the breast, defined as prominent hyperplasia of the lobules with sclerosis of the interlobular stroma. It commonly presents as a tumorlike mass clinically. Sclerosing lobular…

OBJECTIVE. Conversion of bone marrow in the extremities from red to yellow is a normal maturation process. Marrow reconversion is present when expected yellow marrow is replaced with active red marrow, and it tends to occur at times of physiologic…

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…

Within the field of elastography, a relatively new approach analyzes the limiting case of shear waves established as a reverberant field. In this framework, it is assumed that a distribution of shear waves exists, oriented across all directions in 3D…

Objective Strain ratio (SR) is a semiquantitative parameter in differentiating benign from malignant tumors in breast ultrasound elastography. Currently, SR is computed manually and, thus, user dependent. The objective of this study was to evaluate…
