the application of magnetic resonance to diagnostic medical imaging stands as one of the great scientific achievements in the past 50 years. magnetic resonance techniques are easily applied to organs which remain stationary during the imaging procedure, such as the brain and musculoskeletal system. imaging of moving heart structures and circulating blood is considerably more difficult.   clinic...

the purpose of this study was to investigate magnetic resonance imaging (mri) of the normal feline eyeand optic nerves using t1-weighted and t2-weighted images. a total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. magnetic resonance imaging data werecollected using gemsow (philips) at a magnetic field strength of 1.5 t. dorsal, sagittal, a...

In this paper, the numerical design and simulate a biosensor to detect tumors and cancerous tissues by using metamaterial structures in the microwave regime are presented. The presented structure consists of a microstrip transmission line and a split ring resonator (SRR) that form a bandpass filter and has a unique resonance frequency. Given that cancerous tissues have larger volumes of water t...

abstract the current mainstay of treatment in spontaneous intracranial hypotension (sih) is an epidural blood patch (ebp). although magnetic resonance imaging (mri) has a well-established role in the diagnosis of sih, imaging features regarding the treatment efficacy of ebp have rarely been discussed. we therefore sought to investigate and compare the sequential brain mri studies before and aft...

Density functional theory methods(DFT) and natural bond orbital (NBO) analysis were used to investigate the effects of isomerism and side chain mutation at a microscopic level on the stability, binding energy and NMR/NQR tensors of structural isomers, L- methionylasparagine (Met-Asn) and L- asparagylmethionine (Asn-Met) in the gas phase. The results represented that the isomerism and side chain...

magnesium oxide nanotubes of finite length are investigated by the density functional theory (dft) at the b3lyp/6-31g (d) level. the (6, 0) zigzag and (4, 4) armchair of mgo nanotubes were considered and nuclear magnetic resonance properties including isotropic and anisotropic chemical shielding parameters (csi and csa) were calculated for 25mg and 17o atoms of the optimized structures for the ...
