a practical and new method for the synthesis oxindole substituted pyrrolo[2,3-d]pyrimidines by the condensation of isatin, acetophenone and 6-amino-uracil under ultrasound irradiation conditions at 60 °c was described. the reaction was developed via a sequential tandem process to afford the oxindole substituted pyrrolo[2,3-d]pyrimidines in good to excellent yields. all reactions performed effic...

OBJECTIVE To verify the utility of the lateral femoral cutaneous nerve (LFCN) ultrasound-guided conduction technique compared to that of the conventional nerve conduction technique. METHODS Fifty-eight legs of 29 healthy participants (18 males and 11 females; mean age, 42.7±14.9 years) were recruited. The conventional technique was performed bilaterally. The LFCN was localized by ultrasound. ...

Background: In conventional ultrasonography, the ultrasound image is not labeled with information on location or orientation of transducer. There also no parts body under examination. Objectives: This study aimed to investigate efficacy navigation-loaded including real-time transducer and inspection site, compared ultrasound. Patients Methods: After obtaining approval from institutional review ...

background tomosynthesis is a new technology of digital mammography that enables the acquisition of a three - dimensional image and allows visualization of cancers not apparent by conventional mammography. ultrasound (us) is also used for tumor monitoring, which is highly operator dependent and has some problems with reproducibility. us is also an easily available and noninvasive modality. our ...

Objectives: In this study we sought to evaluate whether elastography targeted biopsy improves the detection rate of PCa (prostate cancer) compared to systematic biopsy guided by conventional grayscale ultrasound (GSU). Materials and method: We conducted a prospective study and enrolled 240 patients on which we performed a 12 core prostate biopsy by conventional ultrasound guidence or elastograp...

PURPOSE To demonstrate the usefulness of ultrasound biomicroscopy in detecting the morphological changes in the lens caused by the spontaneous absorption of lens material and to detect fundus abnormalities in a patient with Hallermann-Streiff syndrome. METHODS Case report of an infant diagnosed at the age of 2 months as having Hallermann-Streiff syndrome. RESULTS Spontaneous lens absorption...

Conventional two-dimensional intracoronary ultrasound enables the extent, distribution, and therapy of atherosclerotic plaques to be studied as it provides a unique tomographic visualization of both the vascular lumen and wall'". The most important limitation of two-dimensional intracoronary ultrasound in pre/poststudies is the matching of the target sites for serial measurement. This problem i...

A technique is developed to simultaneously acquire ultrasound and photoacoustic (PA) images based on a linear transducer array. The system uses conventional ultrasound for rapid identification of potential targets. After a target is identified, the ultrasound echo and PA signals can be simultaneously obtained with optimized excitation and a signal collection sequence. The corresponding ultrasou...
