Sound can levitate objects of different sizes and materials through air, water and tissue. This allows us to manipulate cells, liquids, compounds or living things without touching or contaminating them. However, acoustic levitation has required the targets to be enclosed with acoustic elements or had limited manoeuvrability. Here we optimize the phases used to drive an ultrasonic phased array a...

we present a case report of bupropion-induced diplopia in a 26-year-old woman who suffered from atypical depression. âfter four weeks of taking bupropion (225 mg per day) she complained of headaches, blurred vision, and diplopia. no neurological and ophthalmologic abnormal signs were found. her brain magnetic resonance imaging (mrï) and magnetic resonance venography (mrv) were normal as well. â...

Modern challenges of food science require a new understanding of the determinants of food quality and safety. Application of advanced imaging modalities such as magnetic resonance imaging (MRI) has seen impressive successes and fast growth over the past decade. Since MRI does not have any harmful ionizing radiation, it can be considered as a magnificent tool for the quality control of food prod...

The acoustic and articulatory properties of fricative speech sounds are being studied using magnetic resonance imaging (MRI) and acoustic recordings from a single subject. Area functions were derived from a complete set of axial and coronal MR slices using two different methods: the Mermelstein technique and the Blum transform. Area functions derived from the two techniques were shown to differ...

kienbock's disease, which is an idiopathic osteonecrosis and collapse of the lunate bone, is an uncommon disease in children. this report describes a case of an 11-year-old girl, who presented with avascular necrosis of lunate bone confirmed by radiographic and magnetic resonance imaging evidence. after a short period of casting, the case was fully recovered within one year. the signal change w...

purpose: to assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in cardiac magnetic resonance of patients with history of remote myocardial infarction. materials and methods: the cardiac magnetic resonance images of sixty patients with history of remote st segment or non-st segment elevation myocardial infarction were revi...

magnetic resonance imaging (mri) contrast agents most commonly agents used in diagnosing different diseases. several agents have been ever introduced with different peculiar characteristics. they vary in potency, adverse reaction and other specification, so it is important to select the proper agent in different situations. we conducted a systematic literature search in medline/pubmed, web of s...
