Seroprevalence of antibodies against SARS-CoV-2 among public community and health-care workers in Alzintan City of Libya
Abstract A study was conducted to determine the seroprevalence of antibodies against SARS-CoV-2 among public community and health care workers in Alzintan City, Libya. During the period from 2/4/2020… Expand
Dynamic Oxygen-Enhanced MRI of Cerebrospinal Fluid
Oxygen causes an increase in the longitudinal relaxation rate of tissues through its T1-shortening effect owing to its paramagnetic properties. Due to such effects, MRI has been used to study… Expand

OBJECTIVE In a clinical setting, lipoma can sometime show low signal intensity on susceptibility-weighted imaging (SWI) mimicking hemorrhage. The purpose of this study was to evaluate the fat-water… Expand
Visualization of lenticulostriate arteries at 3T: Optimization of slice-selective off-resonance sinc pulse-prepared TOF-MRA and its comparison with flow-sensitive black-blood MRA.
RATIONALE AND OBJECTIVES To optimize visualization of lenticulostriate artery (LSA) by time-of-flight (TOF) magnetic resonance angiography (MRA) with slice-selective off-resonance sinc (SORS)… Expand

BACKGROUND AND PURPOSE: A thorough knowledge of fetal growth and development is key to understanding both the normal and abnormal fetal MR imaging findings. We investigated the size and signal… Expand
Which to choose for volumetry : MPRAGE or SPACE ?
Introduction: From a clinical viewpoint, T1-weighted images is used to evaluate lesion signal at pre& post-contrast enhancement. Especially in contrast-enhanced cases, T1-weighted 3D variable flip… Expand
Dynamic oxygen-enhanced MRI of cerebrospinal fluid : IR FASE vs . FASE
Target audience: Those who have interest in CSF analysis and contrast media. Purpose: To compare the ability to dynamically track oxygen enhancement (OE) of cerebrospinal fluid (CSF) between 3-T MRI… Expand
High resolution distortion-free diffusion-tensor imaging of craniovertebral junction
Diffusion-weighted imaging (DWI) using single-shot echo-planar imaging (SS-EPI) has been used widely for clinical applications, especially in the acute brain ischemia. However this method suffers… Expand
