Introduction Serial measurements of the number of follicles and their growth by ultrasound is a standard way of monitoring fertility treatments using controlled ovarian stimulation. This is stressful for both the patient and the professional. Self-operated endovaginal telemonitoring (SOET) is more patient friendly and less time-consuming. Aim of the study The goal of the study is to see if th...

Introduction: Because establishing venous access in patients can be difficult and time consuming, the use of ultrasound to guide the insertion of peripheral intravenous catheters has become more common. Anecdotal evidence indicates ultrasound-guided catheter insertion may result in decreased catheter survival in the vein (dwell-time), but there is little evidence to support this observation. Th...

Background & Aim: Restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are being imposed because of their carcinogecity . Experimental: In this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of  Flomideschema parviflorum through response surface methodology by Fulin Ci...

With the increasing role played by ultrasound in clinical diagnostics, ultrasound training in medical education has been becoming very important. The clinical routine is for ultrasound to be trained on real patients; therefore, monitored and guided examinations involving medical students are quite time constrained. To be realistically effective, a computerized ultrasound simulation would provid...

BACKGROUND Although percutaneous renal biopsy remains an essential tool in the diagnosis and treatment of renal diseases, in recent times the traditional procedure of nephrologists has been performed by non-nephrologists rather than nephrologists at many institutions. The present study assessed the safety and adequacy of tissue yield during percutaneous renal biopsy according to practitioners a...

The simulation of ultrasound wave propagation is of high interest in fields as ultrasound system development and therapeutic ultrasound. From a computational point of view the requirements for realistic simulations are immense with processing time reaching even an entire day. In this work we present a framework for fast ultrasound image simulation covering the imaging pipeline from the initial ...

Background and Objective: Pain is one of the most common complications after thyroidectomy. Opioid administration can overcome this complication, however, it has some side effects, including nausea and vomiting. So, the use of local anesthetic instead of opioids is a good alternative. This study was conducted to evaluate and compare the effect of ultrasound-guided superficial cervical plexus bl...

the outcome and proper management of fetal hydronephrosis have not been completely defined. the purpose of this study was to determine incidence and outcome of infants with a history of prenatal hydronephrosis diagnosed by ultrasound. in a three-year period from 2000 to 2003 we identified 211 cases (271 renal units) of fetal hydronephrosis in which renal pelvic anteroposterior diameter was more...

Introduction: The medical applications of ultrasound on human brain are highly limited by the phase and amplitude aberrations induced by the heterogeneities of the skull. However, it has been shown that time reversing coupled with amplitude compensation can overcome these aberrations. In this work, a model for 2D simulation of the time reversal mirror technique is proposed to study the possibil...
