To assess two-dimensional phase-encoded proton chemical shift imaging for potential clinical application in presurgical localization of temporal lobe epilepsy (TLE).Interictal studies were performed 25 patients (17 unilateral, eight bilateral epileptogenic abnormalities) and 12 healthy volunteers. Results compared with those electroencephalography. For each lobe, the volume interest (VOI) included mesial, lateral, anterior, posterior areas.The zone was characterized by an abnormal pattern...
We studied temporal changes of brain sodium and apparent diffusion coefficient (ADC) in a lobe epilepsy (TLE) rat model using kainic acid (KA).In situ three-dimensional 23Na magnetic resonance imaging (MRI) proton diffusion-weighted (DWI) were used. KA at dose 10 mg/kg body weight 12 adult Sprague Dawley rats weighing 228-318 g (268 +/- 25 g) used.Twenty-four hours after injection, (MR) visible levels increased both the pyriform cortex (+90%) amygdala (+68%) insignificantly hippocampus...
Background and Purpose Magnetic resonance (MR) diffusion-weighted imaging (DWI), a noninvasive procedure, may play an important role in detecting accurately localizing the extent of evolving infarction within period immediately following stroke. We evaluated sensitivity specificity DWI ischemia compared quantitative measure derived from DWI, apparent diffusion coefficient (ADC), with autoradiographic cerebral blood flow (CBF) experimental model focal rats. Methods MR data were obtained...
Recently, magnetic resonance imaging (MRI) has been reported to be clinically useful, in selected cases, patients with melanocytic skin lesions. This report describes good resolution, useful MRI scans of squamous cell carcinoma, dermatofibroma, and primary cutaneous B‐cell lymphoma. The tumor depth measured by was excellent correlation Breslow's measurements, indicating that is probably the radiologic technique choice for preoperative evaluation extent recurrent tumors. also provides...
During the deposition of Chang-7 (Ch-7) and Chang-6 (Ch-6) units in Upper Triassic, gravity flows were developed widely a deep lake southwestern Ordos Basin, China. Based on cores, outcrops, well-logs well-testing data, this paper documents sedimentary characteristics gravity-flow deposits constructs depositional model. Gravity-flow study area comprise seven lithofacies types, which are categorised into four groups: slides slumps, debris-flow-dominated lithofacies,...
Oxidation behavior of Super304H and HR3C steel in high temperature steam from an ultra-supercritical coal-fired boiler was investigated this paper. The results showed that the oxidized surface ware composed Fe2O3, Cr2O3 FeCr2O4, oxide scale had a thickness 50–70 μm. In addition, about 20μm contained few pitting. oxidation product layer two samples could be divided into layers, including outer enriched O element Fe element, inner Cr element. Furthermore, spalling observed on sample.
Magnetic resonance diffusion-weighted imaging (MR-DWI) is sensitive to the diffusibility of water and may offer characterization anatomical localization stroke leading early tailored therapeutic intervention. We compared DWI, apparent diffusion constant (ADC), autoradiographic cerebral blood flow (CBF) in a model focal ischemia rat. Sprague-Dawley rats were embolized with single silicone cylinder injected into internal carotid artery. Both common carotids permanently ligated. The animals...
To explore the related factors to influence curative effect of focused ultrasound treatment for non neoplastic epithelial disorders vulva.A total 382 patients with vulva were included in this study and treated by ultrasound. During after treatment, symptoms physical signs subjects observed, efficacy was evaluated. We analyzed relation between pathologic type, age, course, area, or itch degree effect.Symptoms all relieved, appearance color became normal a effective rate 99.74%. The cure...
Ni/MoS 2 composite coatings with different content of MoS were produced on the surface 1045 steel by laser cladding technology. SEM and EPMA used to analyze microstructures micro area compositions coatings. Dry friction wear properties tested tester. The results indicate that coating are large quantities different-form white silicides black sulfides distributing substrate. mainly consist Cr x S y , FeS. When is 9%, exhibits best tribological properties.

This manuscript presents a novel scheme to achieve high-resolution laser-radar ranging with small sample number under low signal-to-noise ratio (SNR) conditions. To reduce the number, Restricted Isometry Property-based optimal multi-channel coprime-sampling (RIP-OMCS) strategy is established. In RIP-OMCS strategy, data collected across multiple channels very rates can record accurate range information on each target. Further, asynchronous problem caused by channel sampling-time errors...
This manuscript presents a novel framework for high-resolution and robust microwave correlation imaging. In order to generate more diverse random radiation field distribution, the unified (URRF) model is proposed. The URRF can accurately characterize joint modulation in signals’ phase, amplitude, frequency. Furthermore, we build parametric imaging based on which clearly describes relationship between image be reconstructed signals by model. By using this model, reconstruction of an converted...
Precise localization of the epileptogenic zone in patients suffering from mesial temporal lobe epilepsies is a prerequisite for surgery. For this purpose, scheme selecting volume interest an oblique plane covering head, body, and tail hippocampal formation (HF) was implemented water-suppressed proton chemical shift imaging (CSI) acquisition. This approach, evaluated by consecutively acquired CSI spectra both lobes, demonstrates that it can potentially be routine technique clinical diagnosis....
Herein, powders composed of La2Zr2O7 (LZ) and ZrO2 phases were synthesized by an in situ reaction using a sol-spray pyrolysis method; moreover, 24 mol% LaO1.5-ZrO2 (volume ratio = 1 : 1) characterized XRD, Raman spectroscopy, SEM, TEM. XRD results showed that the samples maintained tetragonal pyrochlore LZ phase from 900 to 1100 °C. The addition could be helpful stabilization t-ZrO2 decreasing grain size ZrO2. SEM revealed homogeneously distributed sintered bulk. HRTEM suggested crystal...
Abstract The editing pulse sequence DEPT (D. T. Pegg, D. M. Doddrell, and R. Bendall, J Chem. Phys. 77, 2745 (1982)) was modified using a scheme of various composite pulses 16‐step phase cycling to obtain proton‐decoupled natural‐abundance 13 C edited subspectra solid tumors.

Abstract A one‐dimensional phase‐encoded spectroscopy sequence was implemented on a GE 1.5‐T Signa imager and the feasibility of its application to monitor 31 P metabolities superficial tumors demonstrated. Serial spectra I‐cm slices with adequate signal‐to‐noise ratio insignificant T 2 weighting can be obtained in 28 min. The degree “bleeding” effect reduced increased phase‐encoding steps. © 1989 Academic Press, Inc.
