thisis a case report of a 24-year-old man who presented with increased pain and firm swelling of the right foot after a minor twisting injury. radiography, computed tomography (ct) and magnetic resonance imaging (mri) findings showed ancillary information that was helpful for surgical treatment. the final diagnosis was confirmed aschondroblastoma of the navicular bone based on the pathology rep...

conclusions although in our study washout pattern was the most powerful indicator for malignant pathology in non mass like enhancing lesions, more studies with larger sample size needs in this regard. background several studies on the diagnostic efficacy of mri has not real consensus for the accuracy of mri characteristics in non mass like breast lesions, and the number of malignant lesions in ...

The development of the UIUC Virtual Spectrometer (UIUC-VS), an interactive, Java-based simulation and tutoring system, is discussed. The apprenticeship model of learning is utilized to create a learning environment for the study of a one-dimensional proton nuclear magnetic resonance (NMR) experiment, with the goal of linking theoretical knowledge with practical operational experience. Active, e...

We study resonant two-photon ionization of helium atoms via the 1 s 3 p , 4 and 5 P states using 15 th harmonic a titanium-sapphire laser for excitation weak fraction field ionization. The phase photoelectron wavepackets is measured by an attosecond interferometric technique, 17 harmonic. perform experiments with angular resolution velocity map imaging spectrometer high energy magnetic bottle e...

Electrically detected magnetic resonance (EDMR) is an effective spectroscopic method utilized for characterizing semiconductive solid-state materials. High spin sensitivity and the capability to explore spin-dependent transport mechanisms, which are crucial development of semiconductor devices, defining it from other methods based on resonance. frequency high field EDMR implementation was motiv...

in this paper, a novel decision based median (dbm) filter for enhancing mr images has been proposed. the method is based on eliminating impulse noise from mr images. a median-based method to remove impulse noise from digital mr images has been developed. each pixel is leveled from black to white like gray-level. the method is adjusted in order to decide whether the median operation can be appli...

brachial plexus injury (bpi) is an uncommon complication of median sternotomy capable of causing a permanent or transitory sensitivity and/or motor function impairment in the upper limbs. during a cardiac surgery through sternotomy, for the assessment of the thoracic cage configuration and the site of mediastinal structures, a broader surgical field may be required. if the sternal retractors ar...
