Background: Diagnostic ultrasound has been used to detect human disease especially fetus abnormalities in recent decades. Although the harmful effects of diagnostic ultrasound on human have not been established so far, several researchers showed it has had bioeffects in cell lines and in experimental animals. Three-dimensional (3D), four-dimensional (4D), and color Doppler sonography are new te...

Background: To ascertain whether using ultrasound guidance during intrauterine insemination (IUI) could increase pregnancy rates. Materials and Methods: The population under study consisted of 73 consecutive couples subjected to IUI in our Human Reproduction Unit, between September and December 2006, with a total of 231 IUI cycles performed. The patients were randomized using a computer-generat...

conclusions sonography is valuable method in diagnosis pneumothorax in unstable patients after invasive thoracic procedures. background ultrasound is the choice modality in the unstable patients and after performing certain procedures, such as a thoracentesis or the placement of a central venous line, which helps to rule out an iatrogenic pneumothorax. upright ap radiograph has less sensitivity...

background and aims: infraclavicular nerve block (icnb) is one of the most efficacious peripheral nerve blocks for upper extremity procedures, associated with several potential complications. recently, some authors have recommended ultrasound-guided peripheral nerve block for icnb. the current study is aimed to compare the outcomes of icnb utilizing combined ultrasound guidance and neurostimula...

abstractbackground : in order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 mhz low level ultrasound based on °oh radicals generated by acoustic inertial cavitation in aqueous solution was monitor...

In this investigation a simple synthetic method for the synthesis of trifluoromethyl-1H-benzo[e][1,2,4]triazolo[1,2-a][1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo [5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones has been developed using urazole or phthalazine and aceteimidoyl chloride derivatives at room temperature under ultrasound irradiations. In the comparison to the conventi...

Background:  Medial pinning is one of the most controversial aspects of the surgical treatment of supracondylar fractures (SHF) owing to the risk of ulnar nerve injury.  Aim: To evaluate the safety and usefulness of medial pinning for SHF using ultrasound imaging for ulnar nerve visualization.   Methods: Fifteen children, with a mean age of 60 months, with displaced SHF were treated with a cros...

introduction: transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. in this study, we compared and evaluated the treatment effects of dual frequency irradiatio...
