OBJECTIVE To illustrate the possible role of cerebral oximetry and stroke distance as measured by Doppler ultrasound in monitoring the critically ill patient non-invasively in the emergency department. METHODS Five critically ill patients were monitored with either cerebral oximetry or both cerebral oximetry and stroke distance (the distance travelled by blood in the aorta with each ventricul...

BACKGROUND The aetiology of central nervous system lesions observed in cerebral cyclosporine neurotoxicity remains controversial. CASE PRESENTATION We report a 48-year-old woman with a non-severe aplastic anaemia who presented with stroke-like episodes while on cyclosporine treatment.Transcranial Doppler ultrasound revealed severely elevated flow velocities in several cerebral vessels, consis...

OBJECTIVE To determine if power Doppler ultrasound examination of the endometrium can contribute to a correct diagnosis of endometrial malignancy in women with postmenopausal bleeding and endometrium > or = 5 mm. METHODS Eighty-three women with postmenopausal bleeding and endometrium > or = 5 mm underwent gray-scale and power Doppler ultrasound examination using predetermined, standardized se...

Hen’s native chicken reproductive organ health status evaluation is important for raising Indonesian native chicken in order to support protein supply for people demand. This study aimed to discover the images of Indonesian hen’s native chicken reproductive organ using ultrasonography. There were 18 hens that used in this study and divided into two groups, 15 hens for brightnessmode ultrasonogr...

Eagle syndrome is caused by an elongated styloid process or calcified stylohyoid ligament. The stylocarotid variant with neurologic symptoms is rare and presents a diagnostic challenge. Patients may present with transient ischemic attacks, syncope, or less well defined symptoms like episodic dizziness. We report use of vascular laboratory testing in the management of Eagle syndrome. In one pati...

Bubble cavitation is one of the major mechanisms for ultrasound-induced bioeffects. Characterising the bubble dynamics, expansion and collapse, is of importance in understanding the cavitation phenomenon and estimating the consequent outcome. In this study, Doppler ultrasound method was firstly used to measure the bubble wall velocity. Bubbles were generated in water using a beam of high-intens...

Doppler ultrasound was used to assess the response to serial drug testing in a patient with primary pulmonary hypertension. There was a close correlation between the pressure estimated by Doppler and the pulmonary arterial systolic pressure measured invasively (r = 0.98). Continuous-wave Doppler ultrasound, although not a substitute for initial Swan-Ganz catheterization, may obviate the need fo...

BACKGROUND Although techniques for off-pump coronary artery bypass grafting (CABG) are continually being refined, angiographic follow-up studies have indicated a higher rate of anastomoses-related stenoses than expected after traditional on-pump CABG. This study was performed to evaluate the use of intraoperative epicardial color Doppler ultrasound to quality-assess left internal mammary artery...

STUDY DESIGN Cross-sectional observational study. OBJECTIVES To investigate the presence of soft tissue hyperemia in plantar fasciitis with power Doppler ultrasound. BACKGROUND Localized hyperemia is an established feature of tendinopathy, suggesting that neurovascular in-growth may contribute to tendon-associated pain in some patients. The presence of abnormal soft tissue vascularity can b...

Stars closely approaching the massive black hole in the center of the Galaxy provide a unique opportunity to probe post-Newtonian physics in a yet unexplored regime of celestial mechanics. Recent advances in infrared stellar spectroscopy allow the precise measurement of stellar Doppler shift curves and thereby the detection of β post-Newtonian effects (gravitational redshift in the black hole’s...
