PURPOSE: To determine whether addition of quality measure (QM) of shear-wave (SW) velocity (Vs) estimation can increase SW elastography sensitivity for breast cancer. MATERIALS AND METHODS: With written informed consent, this institutional review…

The Society of Radiologists in Ultrasound convened a panel of specialists from radiology, hepatology, pathology, and basic science and physics to arrive at a consensus regarding the use of elastography in the assessment of liver fibrosis in chronic…

Purpose To assess the performance of computer-aided diagnosis (CAD) systems and to determine the dominant ultrasonographic (US) features when classifying benign versus malignant focal liver lesions (FLLs) by using contrast material-enhanced US cine…

The authors identified the origin of a high-density artifact with mammography film. An acrylic ramp phantom (thickness, 0-7 cm) was used to create a continuously variable radiation exposure. A perturbation in the curve of optical density versus…

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…

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…

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…

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…

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…

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…

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…

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…

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…

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…

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. 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…

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…

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…

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…

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: 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…

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…

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,…
