Reproducibility of Ultrasound Measurements
Background-The pattern of growth of the uterus was examined by ultrasound examinations of 358 girls who attended a paediatric endocrine outpatient department but were shown not to have any endocrine defect. Method-The uterus was measured in length and width at the cervix and at the fundus (cm). Endometrial thickness was measured (mm). Scans were divided by Tanner breast stage and the dimensions...
متن کاملReproducibility of carotid artery Doppler frequency measurements.
Doppler sonography of 29 extracranial carotid arteries was performed twice within three days or less. Angiography revealed stenoses with from 10 to 95% diameter reduction in 25 internal carotid arteries whereas four vessels were found to be normal. The systolic peak frequency of the internal carotid artery read from the Doppler spectrum (n = 29) could be reproduced very well. This was shown by ...
متن کاملReproducibility of measurements of cardiac output in newborn infants by Doppler ultrasound.
Interobserver reproducibility in deriving cardiac output by measuring aortic blood flow velocity and diameter with imaging and Doppler ultrasound was investigated in 20 healthy infants born at full term. Aortic diameter was measured in three ways. Mean blood flow velocity was measured at three sites with both continuous wave and pulsed Doppler. Two observers carried out each study independently...
متن کاملCarotid intima-media thickness and hemodynamic parameters: reproducibility of manual measurements with Doppler ultrasound.
AIMS To evaluate the carotid ultrasound intra- and interobserver agreements in a common clinical scenario when making manual measurements of the intima-media thickness (IMT) and peak systolic (PSV) and end diastolic (EDV) velocities in the common (CCA) and the internal carotid (ICA) arteries. MATERIAL AND METHODS Three different experienced operators performed two time-point carotid ultrasoun...
متن کاملReproducibility of linear cardiac output measurement by Doppler ultrasound alone.
Inclusion of a pig aorta in an artificial circulation with pulsed blood flow allowed correlation of minute distance, measured in the aorta by Doppler ultrasound, and absolute blood flow, measured by timed blood-volume collection. The correlation coefficient was 0.99 with a standard error of prediction that was 5.4% of the minute distance predicted at a standard flow rate of 5 litres per minute....
