INTRODUCTION Brachial plexus blockade is a time-tested technique for upper limb surgeries. The classical approach using paresthesia technique is a blind technique and may be associated with a higher failure rate and injury to the nerves and surrounding structures. To avoid some of these problems, use of peripheral nerve stimulator and ultrasound techniques were started which allowed better loca...

The last step of a successful pregnancy is the safe delivery of the fetus. An important question is if the delivery should vaginal or operative. In addition to the use of conventional antenatal ultrasound, the use of intrapartum ultrasound to evaluate fetal head station, position, cervical ripening, and placental separation is promising. This review evaluates and summarizes the usefulness of in...

The study was aimed to evaluate the diffuse liver diseases by using 2D-conventional ultrasound. A prospective, analytic, and descriptive study of abdominal ultrasound images of 100 subjects with diffuse liver diseases; fatty infiltration, acute hepatitis, chronic hepatitis and cirrhosis. An ultrasound assesses characteristics of the liver including (size, echogenicty, outline and intra hepatic ...

Background: With the technical development, ultrasound tends to overpass its limits and to become the main investigation tool even for situations when it was traditionally considered “second best”. It is more convenient both for patient and doctor, less expensive and has real diagnostic value. Objective: The present paper, and its graphic back-up, are intended as a visual testimony of the fact ...

Conventional beamforming used in pulse-echo ultrasound images results in an inherent blurring. This blurring limits the resolution, and hence the utility, of pulse-echo ultrasound in clinical applications. Ng et al. developed an expectationmaximisation algorithm to enhance blurred, two-dimensional RF ultrasound images. It is important that the algorithm is intialised well in order that converge...

PURPOSE To compare torsional versus combined torsional and conventional ultrasound modes in hard cataract surgery regarding ultrasound energy and time and effect on corneal endothelium. SETTINGS Kasr El Aini hospital, Cairo University, and International Eye Hospital, Cairo, Egypt. METHODOLOGY Ninety-eight eyes of 63 patients were enrolled in this prospective comparative randomized masked cl...

OBJECTIVE To evaluate the value of conventional ultrasound and contrast-enhanced ultrasound (CEUS) in determining the severity of active Crohn's disease. METHODS Thirty-seven patients who were considered to be in active period of Crohn's disease were included. Conventional ultrasound was employed to measure the thicknesses of interior, exterior and the whole bowel walls. Qualitative and quant...

Contrast-enhanced ultrasound (CEUS) has been used for diagnosing acute pancreatitis (AP), particularly severe acute pancreatitis (SAP). However, the diagnostic difference between CEUS and conventional ultrasonography (CUS) for AP and SAP has not been reported. The aim of the present study was to investigate the diagnostic accuracy of CUS and CEUS for AP. A total of 196 patients clinically diagn...

This study aimed to investigate the characteristic features of craniocerebral gunshot wounds by conventional ultrasound (CUS) and evaluate the efficacy of contrast-enhanced ultrasound (CEUS) in differentiation of tissue condition in wounds. Twenty crossbreed dogs (treatment: N = 15; control: N = 5) were used in the study. Pipe-shaped hyperechoes of varying size were found by CUS in most of the ...
