The transition from compensatory concentric remodeling to myocardial failure is not completely understood in humans. To investigate determinants of incipient dysfunction, we examined the association between and regional LV function asymptomatic participants Multi-Ethnic Study Atherosclerosis (MESA).Myocardial tagged MRI was performed. Regional expressed as peak systolic midwall circumferential strain (Ecc) analyzed 441 consecutive studies by HARP (Harmonic Phase) tool. Peak Ecc correlated...
To evaluate the accuracy and reproducibility of quantitative chemical shift-encoded (CSE) MRI to quantify proton-density fat-fraction (PDFF) in a fat-water phantom across sites, vendors, field strengths, protocols.Six sites (Philips, Siemens, GE Healthcare) participated this study. A containing multiple vials with various oil/water suspensions (PDFF:0%-100%) was built, shipped each site, scanned at 1.5T 3T using two CSE protocols per strength. Confounder-corrected PDFF maps were...
We study a demand response (DR) problem from utility (also referred to as operator)'s perspective with realistic settings, in which the faces uncertainty and limited communication. Specifically, does not know cost function of consumers cannot have multiple rounds information exchange consumers. formulate an optimization for minimize its operational considering time-varying DR targets responses develop joint online learning pricing algorithm. In each time slot, sends out price signal all...
We report the development of a new robotic system for direct image-guided interventions (DIGI; images acquired at time intervention). The manipulator uses our previously reported pneumatic step motors and is entirely made electrically nonconductive, nonmetallic, nonmagnetic materials. It orients needle-guide with two degrees freedom (DoF) about fulcrum point located below guide using an innovative remote center motion parallelogram type mechanism. depth manual needle insertion preset third...
Abstract A technique for fast imaging of regional myocardial function using a spiral acquisition in combination with strain‐encoded (SENC) magnetic resonance (MRI) is presented this paper. This technique, which termed fast‐SENC, enables scan durations as short single heartbeat. reduced field view (FOV) without foldover artifacts was achieved by localized SENC, selectively excited the region around heart. The two images required SENC (low‐ and high‐tuning) were acquired an interleaved fashion...
Spatially and temporally explicit information on the biomass in terrestrial ecosystems is essential to better understand carbon cycle achieve vegetation resource conservation. As a climate-sensitive critical ecological function area, accurate monitoring of spatiotemporal variation grassland aboveground (AGB) important Three-River Headwater Region (TRHR) China. In this study, based field observation, remote sensing, meteorological topographical data, we estimated AGB TRHR analyzed its change...
We introduce submodular hypergraphs, a family of hypergraphs that have different weights associated with cuts hyperedges. Submodular arise in clustering applications which higher-order structures carry relevant information. For such we define the notion p-Laplacians and derive corresponding nodal domain theorems k-way Cheeger inequalities. conclude description algorithms for computing spectra 1- 2-Laplacians constitute basis new spectral hypergraph methods.
In gynecologic cancers, magnetic resonance (MR) imaging is the modality of choice for visualizing tumors and their surroundings because superior soft-tissue contrast. Real-time MR guidance catheter placement in interstitial brachytherapy facilitates target coverage, would be further improved by providing intraprocedural estimates dosimetric coverage. A major obstacle to dosimetry time needed trajectory reconstruction. Herein authors evaluate an active tracking (MRTR) system which provides...
Purpose To evaluate the accuracy of T 2 ‐based whole‐brain oxygen extraction fraction (OEF) estimation by comparing it with gold standard 15 O‐PET measurements. Methods Sixteen healthy adult subjects underwent MRI and OEF measurements on same day. On MRI, was quantified ‐relaxation‐under‐spin‐tagging (TRUST) based subject‐specific hematocrit. The TRUST compared to averaged produced O‐PET. Agreement between examined in terms intraclass correlation coefficient (ICC) absolute values. In a...
