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…
Positron emission tomography (PET), with the use of F-18 fluorodeoxyglucose (FDG), has been shown to be useful in the evaluation of many tumors as a result of its high sensitivity and specificity. There are instances, however, in which false-positive…
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…
The composition of cartilage is predictive of its in vivo performance. Therefore, the ability to assess its primary macromolecular components, proteoglycan (PG) and collagen, is of great importance. In the current study, we hypothesized that PG…
Screening for breast cancer reduces breast cancer-related mortality and earlier detection facilitates less aggressive treatment. Unfortunately, current screening modalities are imperfect, suffering from limited sensitivity and high false-positive…
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…
Gadolinium contrast administration, usually with magnetic resonance imaging, is an important diagnostic modality in the investigation of neurological pathologies. There is little evidence in the literature suggesting repeated exposure to intrathecal…

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. 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…
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…
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…
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. 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…
