Our aim was to compare polylevolactic acid screws with titanium when used for fixation of the distal tibiofibular syndesmosis at mid-term follow-up. A total 168 patients, a mean age 38.5 years (18 72) who were randomly allocated receive either (n = 86) or metallic 82) included. The Baird scoring system assess overall satisfaction and functional recovery post-operatively. demographic details characteristics injury similar in two groups. follow-up 55.8 months (48 66). scores groups final...
Objectives Researchers continue to seek easier ways evaluate the quality of bone and screen for osteoporosis osteopenia. Until recently, radiographic images various parts body, except distal femur, have been reappraised in light dual-energy X-ray absorptiometry (DXA) findings. The incidence osteoporotic fractures around knee joint elderly continues increase. aim this study was propose two new parameters femur assessment quality. Methods Anteroposterior radiographs mineral density (BMD)...
Chemical Exchange Saturation Transfer Magn-etic Resonance Imaging (CEST-MRI) is a promising approach for detecting tissue metabolic changes. However, due to the constraints of scan time and contrast-noise-ratio, CEST-MRI always exhibits low spatial resolution, hindering clinical applications especially detection small lesions. Many super-resolution (SR) methods have shown good performance in medical images. when applied CEST-MRI, these two shortcomings that may limit their performance....
Motivation: Current unsupervised dynamic-MRI reconstruction algorithms based on DIP uses very low-dimensional latent variables and a single generator for direct non-linear mapping, which may limit the performance. Goal(s): To propose new model algorithm dynamic MRI reconstruction. Approach: We novel Graph-Image-Prior(GIP) model, branched CNN generators to recover image structure, use Graph-Neural-Network(GNN) discover best spatio-temporal manifold. Besides, we devise an ADMM alternately...
Abstract Background Golden angle (GA) radial trajectory is advantageous for dynamic magnetic resonance imaging (MRI). Recently, several advanced algorithms have been developed based on navigator‐interleaved GA to realize free‐running cardiac MRI. However, suffers from the eddy‐current effect, which reduces image quality. Purpose This work aims integrate with clinical MRI acquisition, minimum artifacts. The ultimate goal a high‐quality technique. Methods In this paper, we propose new “swing...

Goal(s): The plug play truncated low rank optimization combined iterative soft thresholding(PNPT-) embedded method was proposed reconstructe data tested accurately estimate the function for dMRI reconstruction. Approach: PNPT- uses nuclear norm thresholding assign different shrink values singular vectors, enabling preservation of essential information while effectively eliminating noise. Results: Impact:...
Motivation: Real time interventional MRI (i-MRI) is essential for MR image guided therapy, but the requirement of high temporal resolution presents a great challenge reconstruction real-time i-MRI. Goal(s): Our goal modifying an improved Partial Separable (PS) model called PS-R to explore potential modified achieve Approach: We with spatial constraint (PS-RSC) and performed retrospective experiments on simulation intervention images verify effectiveness PS-RSC model. Results: Satisfying...
Obtaining high spatial and temporal resolution image in dynamic magnetic resonance imaging is a huge challenge. It effective to use low-rank sparse prior jointly for dMRI reconstruction. However, the models represented tensor data into matrix, which can not completely explore spatiotemporal correlation information. Besides, using nuclear norm as convex surrogate of rank function enforce low-rank, may lead sub-optimal result. Hence, we proposed piecewise frequency joint reconstructed data....
Various image reconstruction methods have been proposed to reduce Magnetic resonance (MR) acquisition time. One of recent trends is convolution neuron network (CNN) based deep learning model. However, most these CNN models keep architecture stacking small filters (e.g. 1×1 or 3×3) and the effective receptive field networks limited, which undesired for because random undersampling pattern causes global artifact. We Fourier block (FCB) replace regular filters. FCB can achieve both high...
Golden angle radial trajectory suffers from eddy-current when combined with trueFISP sequence. If additional navigators are required, how to keep golden ratio sampling while maintain stable steady-state is still a problem be solved. In this work, we propose novel profile order, named "swin angle"(swinGA), which able achieve sampling, signal, and navigator acquisition simultaneously. We validated the proposed in static phantom study in-vivo for free-running cardiac imaging. The results show...
Objective: To explore the clinical characteristics, therapeutic methods and effects of blood blister-like aneurysms (BBA) supraclinoid segment internal carotid artery (ICA). Methods: A total 40 patients with BBAs ICA treated at Department Neurosurgery West China Hospital between January 2010 2016 were retrospectively reviewed. There 14 males 26 females mean age 44.7 years (ranging from 25 to 64 years). 38 presented subarachnoid hemorrhage (SAH), 2 found incidentally unruptured in regular...
Objective: To analyze the cell morphological features of hepatosplenic T-cell lymphoma (HSTCL) gamma-delta (γδ) type, differentiate from acute leukaemia (AL). Methods: This was a retrospective study. The clinical data four cases HSTCL γδ type who were treated in Hebei Yanda Ludaopei Hospital 2009 to 2014 collected. Their initial morphology diagnoses other hospitals all leukemia or myelodysplastic syndrome (MDS). Morphological analysis and cytochemical stains their bone marrow (BM) aspiration...
In this study we have realized a real-time free-running cardiac imaging technique which can provide continuous high-temporal-resolution movie of the heart during whole acquisition process. This is based on constrained partial separable model, has been elaborately designed and optimized to achieve maximum reconstruction speed.

Chemical exchange saturation transfer magnetic resonance imaging (CEST-MRI) is a new approach to detect tissue metabolic changes. However, constrained by its low signal-to-noise ratio and long scan time, CEST-MRI usually only able get low-resolution (LR) images in clinical examination, which disadvantageous for the diagnosis of small lesions. But simple interpolation improve resolution will cause severe decrease accuracy analysis. Many deep-learning methods are also not satisfying...
