Video retrieval based on deep convolutional neural network
, 2017 Recently, with the enormous growth of online videos, fast video retrieval research has received increasing attention. As an extension of image hashing techniques, traditional video hashing methods mainly depend on hand-crafted features and transform the ...

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Magnetization transfer (MT) and water exchange via permeability operate on a similar spatiotemporal scale to water diffusion. In this study, we use a simulation‐based approach to characterize how MT and permeability impact (1) diffusion‐weighted MRI (dMRI) measurements from cylindrical substrates and (2) parameter estimation using a ...

MR Spectroscopy Without Water Suppression Using the Gradient Impulse Response Function
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Non‐water‐suppressed proton spectroscopy, 1H‐MRS, is desirable, as retaining the strong water resonance can facilitate automated online data corrections, internal concentration referencing, and monitoring of line narrowing effects in functional MRS.

GABA+‐Edited Magnetic Resonance Spectroscopy Deep Learning Quality Assessment Framework
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Motivated by the need to improve GABA+‐edited magnetic resonance spectroscopy (MRS) quality, we developed a three‐module framework to improve transient averaging based on quality. We hypothesized that training a deep learning (DL) model to differentiate spectrum quality could improve transient averaging compared to traditional ...

Phytochemical Analysis, EarlyView.ABSTRACT Primary brain tumors are life‐threatening diseases. Glioblastoma is the most aggressive type with a poor prognosis. Medulloblastoma is the most common pediatric brain tumor. While surgical treatments often result in recurrences owing to the complex nature of the tumor microenvironment, conventional treatments lower the quality of life of ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...
