abstract   background: hydronephrosis is the most common congenital condition that is detected by prenatal ultrasonography. moreover, the widespread use of prenatal ultrasonography results in an increased recognition of fetal hydronephrosis. prenatal hydronephrosis is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. the presence of hydronephrosis is not synonymous with o...

BACKGROUND Few studies have assessed the utility of chest ultrasonography in the diagnosis of pneumothorax in India. METHODS Chest ultrasonography was undertaken in 126 haemodynamically stable patients, followed by a chest radiograph within 30 minutes. If pneumothorax was not seen on the chest radiograph, a non-contrast computed tomography of the thorax was performed within 3 hours. The time ...

OBJECTIVE To determine if colour Doppler ultrasonography can characterise the nature of intraarticular echogenic structures and synovial villi more precisely than conventional ultrasonography. METHODS This is a prospective study on 20 patients--10 with rheumatoid arthritis and 10 with osteoarthritis. Colour Doppler ultrasonography of the knee joints was performed prior to total prosthetic rep...

introduction: pain control is the most important issue in emergency department management of patients with femoral bone fractures. the present study aimed to compare the procedural features of ultrasonography and nerve stimulator guided femoral nerve block in this regard. method: in this randomized clinical trial, patients with proximal femoral fractures presenting to emergency department were ...

OBJECTIVE The present study examined the reliability and correlation of sialography, salivary gland biopsy, and ultrasonography for Sjögren syndrome (SS) and evaluated the usefulness of ultrasonography as a diagnostic tool for SS compared with sialography and histopathology. STUDY DESIGN Seventy-three patients who underwent sialography, ultrasonography, and salivary gland biopsy were included...

Objective: Ultrasonographic measurements of optic nerve sheath diameter is associated with increased intracranial pressure. Intracranial pressure are usually performed on critical areas or intensive care unit patients. The effect ultrasonographic measurement in predicting pathology the need for surgery mild moderate head trauma has not been evaluated. In our study, we compared cranial computed ...

AIM To clarify the usefulness of three-dimensional (3D) ultrasound in the assessment of the fetal head and brain, according to 3D ultrasound surface reconstruction, multiplanar image analysis, three-dimensional angiography, and volume calculation. METHODS We examined 326 normal fetuses between 10 and 40 weeks of gestation using 3D ultrasound (Voluson, 530D, Medison, Seoul, Korea), mainly with...

In order to localise neuroendocrine tumours of the foregut type (that is, of the stomach, duodenum, and pancreas), 18 patients were studied prospectively by endoscopic ultrasonography, computed tomography, transabdominal ultrasonography, magnetic resonance imaging, and somatostatin receptor scintigraphy. These 18 patients had a total of 25 primary tumour lesions which were verified histological...

formula one legend michael schumacher hit his head severely while skiing on december 29, 2013. he was operated on for brain decompression and left in a coma fighting for life. in such severe brain injury with cerebral contusion and hemorrhage following head trauma, refractory to medical therapy and with increasing cerebral oedema and intracranial pressure, critically low cerebral perfusion can ...
