OBJECTIVE The purpose of this article is to evaluate the feasibility of adenosine-stress dynamic myocardial perfusion imaging (MPI) with 128-MDCT dual-source CT for detecting myocardial ischemia in comparison with conventional catheter coronary angiography and nuclear MPI. SUBJECTS AND METHODS Thirty patients (21 men and nine women; mean [± SD] age, 59.2(More)
OBJECTIVE Recently, the technique of high-resolution magnetic resonance imaging (HR-MRI) has been developed to depict intracranial artery wall. We aimed to compare the vessel wall properties between symptomatic and asymptomatic atherosclerotic middle cerebral arteries (MCA) using HR-MRI. METHODS We studied 26 patients with symptomatic and 35 patients with(More)
A novel nanofibrous composite scaffold composed of super-paramagnetic γ-Fe2O3 nanoparticles (MNP), hydroxyapatite nanoparticles (nHA) and poly lactide acid (PLA) was prepared using electrospinning technique. The scaffold well responds extern static magnetic field with typical saturation magnetization value of 0.049 emu/g as well as possesses nanofibrous(More)
OBJECTIVE Three-dimensional time-of-flight magnetic resonance angiography (3D TOF MRA) has been wildly used in the diagnosis of intracranial artery diseases, but it only shows the arterial lumen and does not delineate the vessel wall. The aim of this study was to assess whether high resolution cross sectional magnetic resonance imaging (HRMRI) could(More)
The soil bacterium Arthrobacter aurescens SK 8.001 produces inulin fructotransferase (IFTase), and liquid chromatography-mass spectrometry (LC-MS) and carbon-13 nuclear magnetic resonance (13C NMR) analysis demonstrated that the main product of the enzyme was difructose anhydride III (DFA III). The IFTase was purified by ethanol precipitation, DEAE(More)
To investigate image quality, radiation dose, and diagnostic performance of prospectively ECG-triggered high-pitch coronary CT angiography (CCTA) at 70 kVp compared to invasive coronary angiography (ICA) as reference standard. Forty-three patients underwent prospectively ECG-triggered high-pitch CCTA at 70 kVp using 30 cc (11 g iodine) contrast medium and(More)
To retrospectively explore the value of apparent diffusion coefficient (ADC) histogram in assessing local aggressiveness of cervical cancer. 53 patients with cervical cancer, including 7 cases at stage IB1, 17 cases at stage IB2 and 29 cases at stage IIA, were subjected to preoperative MRI including diffusion-weighted imaging with b values of 0 and 800(More)
Activation of microglia and consequent release of proinflammatory factors, are believed to contribute to neurodegeneration in Parkinson's disease (PD). Hence, identification of compounds that prevent microglial activation is highly desirable in the search for therapeutic agents for inflammation-mediated neurodegenerative diseases. In this study, we reported(More)
OBJECTIVE The purpose of this study was to evaluate the feasibility of using integrated slice-by-slice shimming (iShim) for improving the image quality of whole-body diffusion-weighted imaging (WBDWI) in patients with plasma disorder at 3 T by comparing to WBDWI using a conventional shimming (3-dimensional [3D] shim) adjustment of each body station.

OBJECTIVE To evaluate the clinical impact of body diffusion weighted imaging (DWI) on the diagnosis and preoperative N staging of cervical cancer. METHODS Twenty-four patients (mean age 37.9 years old) with proved cervical cancer by cervical biopsy and 24 female patients with other suspected pelvic abnormalities received preoperative body DWI scan.(More)
