It is challenging and inspiring for us to achieve high spatiotemporal resolutions in dynamic cardiac magnetic resonance imaging (MRI). In this paper, we introduce two novel models and algorithms to reconstruct dynamic cardiac MRI data from under-sampled k - t space data. In contrast to classical low-rank and sparse model, we use rank-one and transformed sparse model to exploit the correlations ...

We present experimentally-acquired MR image sequence reconstruction results and a review of the recently proposed doubly adaptive temporal update method (DATUM) for the acquisition of dynamic MRI sequences. The DATUM algorithm is novel in providing an estimation and tracking framework for both image reconstruction and the image acquisition inputs. We discuss the difficulty in choosing viable sy...

Background: Despite new advances in liver imaging, it is still difficult to identify and classify hepatic focal lesions. Particularly cancer patients, where accurate tumor staging depends on the definition of lesion for best treatment planning. Aim objectives: was evaluate significance Dynamic Magnetic Resonance identification description hypo-vascular tumor. subjects methods: Our current resea...

OBJECTIVES Using magnetic resonance imaging (MRI), we analyzed the efficacy of the posterior approach lumbar ISOBAR TTL internal fixation system for the dynamic fixation of intervertebral discs, with particular emphasis on its effects on degenerative intervertebral disc disease. METHODS We retrospectively compared the MRIs of 54 patients who had previously undergone either rigid internal fixa...

BACKGROUND AND PURPOSE In computed tomographic imaging of acute intracerebral hemorrhage spot sign on computed tomographic angiography has been established as a marker for hematoma expansion and poor clinical outcome. Although, magnetic resonance imaging (MRI) can accurately visualize acute intracerebral hemorrhage, a corresponding MRI marker is lacking to date. METHODS We prospectively exami...

Magnetic resonance imaging (MRI) provides non-invasive, repetitive measures in the same individual, allowing the study of a physio-pathological event over time. In this study, we tested the performance of 7 Tesla multi-parametric MRI to monitor the dynamic changes of mouse skeletal muscle injury and regeneration upon acute ischemia induced by femoral artery dissection. T2-mapping (T2 relaxation...

As prostate cancer is a biologically heterogeneous disease for which a variety of treatment options are available, the major objective of prostate cancer imaging is to achieve more precise disease characterization. In clinical practice, magnetic resonance imaging (MRI) is one of the imaging tools for the evaluation of prostate cancer, the fusion of MRI or dynamic contrast-enhanced MRI (DCE-MRI)...

Magnetic resonance imaging (MRI) has the potential to become a useful adjunct in breast imaging. Contrast-enhanced breast MRI has demonstrated a high sensitivity in the detection of benign and malignant breast disease. Our study aimed to correlate the dynamic contrast-enhanced MRI appearance of benign phyllodes tumor of the breast with histopathologic findings. We retrospectively reviewed the M...

Accurate local staging of prostate cancer is essential for patient management decisions. Conventional and evolving magnetic resonance imaging (MRI) techniques, such as diffusion- weighted imaging, dynamic contrast-enhanced MRI, and MR spectroscopy, are promising techniques in prostate cancer imaging. In this article, we will review the current applications of conventional and ...
