Despite many uses of ultrasound, some pathologies such as breast cancer still cannot reliably be diagnosed in either conventional B-mode ultrasound imaging nor with more recent elastography methods. Speed-of-sound (SoS) is a quantitative biomarker, which sensitive to structural changes due pathology, and hence could facilitate diagnosis. Full-angle computed tomography (USCT) was proposed obtain spatially-resolved SoS images, however, its water-bath setup involves practical limitations. To...
Our goal was to establish right ventricular (RV) volume and ejection fraction (EF) values in normal volunteers with fast magnetic resonance (MR) imaging using a breath-hold technique, assess the frequency severity of RVEF abnormality cardiac patients compare RV left (LV) data. We performed simultaneously derived LV cine measurements 52 normals 325 coronary artery disease (CAD), acquired valvular (VD), cardiomyopathy (CM), or congenital heart (CHD). reduced 31% (102) all patients, 50% dilated...
Numerous intrinsic and extrinsic wrist ligaments are visible at magnetic resonance (MR) imaging. Because the previously published descriptions of these were often conflicting, authors derived a classification system based on functional perspective their experience with MR imaging, arthroscopy, surgical dissection. This was used to evaluate images 23 cadaveric wrists for presence integrity 16 ligaments. prospectively analyzed by two observers, all findings correlated results arthroscopy. The...
The purpose was to identify features of malignant and non-malignant neoplastic breast disease on galactography estimate their predictive value. This is the largest reported study correlating galactographic morphological patterns with histopathology only blinded study. included 351 consecutive galactograms 161 biopsies performed in patients nipple discharge over a 10-year period. Three radiologists, clinical data histological results, re-evaluated 158 previously who had undergone excision...
To evaluate measurement confounders on 2D shear wave elastography (2D-SWE) of muscle.
Speed-of-sound (SoS) has large potential for tissue and pathology differentiation. We aim to develop a novel Ultrasound Computed Tomography (USCT) technique that can reconstruct local SoS in on conventional ultrasound machines with hand-held linear arrays.
The aim of this study was to differentiate malignant and benign solid breast lesions with a novel ultrasound (US) technique, which measures speed sound (SoS) using standard US transducers intrinsic tissue reflections scattering (speckles) as internal reference.This prospective, institutional review board-approved, Health Insurance Portability Accountability Act-compliant prospective comparison performed prior written informed consent from 20 women. Ten women histological proven cancer 10...
This project evaluated a low-cost sponge phantom setup for its capability to teach and study A- B-line reverberation artifacts known from lung ultrasound numerically simulate sound wave interaction with the using finite-difference time-domain (FDTD) model. Both were reproducible on B-mode imaging as well in FDTD-based simulation. The was found be an easy-to-set up economical tool understanding, teaching, researching occurring ultrasound. FDTD method-based simulation able reproduce provides...
