Ultrasound measurement of atherosclerosis.
Ultrasound Measurement of Atherosclerosis To the Editor: The recent review of intima-media thickness (IMT) measurements by Bots et al,1 while presenting cogent arguments for use of maximum versus mean carotid IMT for studies of interventions, failed to discuss important limitations of IMT. They claim as an important advantage of IMT, as opposed to morbidity and mortality as end-points, the cons...
متن کاملUltrasound Measurement of Kidney Dimensions in Premature Neonates
Background Ultrasonography is a non-invasive and accurate diagnostic method to evaluate urinary system and its anomalies in the neonates. Kidney sonographic measurement can be used as an alternative method to estimate gestational age. The aim of this study was to measure kidney size in preterm neonates and to provide a guide reference for gestational age. <...
متن کاملUltrasound measurement of femoral anteversion.
In a recent article by Lausten, J#{248}rgensen and Boesen (1989) anteversion (AV) of the femoral neck was measured directly, by ultrasound, and by computerised tomography (CT). The authors reported poor correlation between the angles measured by ultrasound and the two other methods, and concluded that ultrasound at present seemed unsuitable for the measurement of femoral anteversion. We believe...
متن کاملContinuous blood pressure measurement with ultrasound.
Cardiovascular diseases are the main cause of death in Germany. A long-term blood pressure measurement is crucial to identify hypertension which can lead to cardiovascular disease. Conventional techniques use the automatic arm cuff method which is painful and provides only intermittent results. A new method for continuous measurement is developed using a DOPPLER ultrasound sensor on a superfici...
متن کاملDirect measurement of circulation using ultrasound
Ultrasound time-of-flight methods employing counter-propagating ultrasonic pulses are utilized for the direct measurement of circulation in vortical flows. Two schemes are described here which involve either a single straight path or a closed path. Both techniques are shown to result in time differences, between the counter-propagating pulses around the path, linearly proportional to the circul...
