But the FDA,the British Medical Ultrasound Society, the American Institute of Ultrasound in Medicine,and many doctors have spoken out against the use of Dopplers at home because of potential for misunderstanding. Due to a lack of training, you might be falsely reassured about a baby's heartbea...
Abnormal placental vascularization and poor placental perfusion.aBradycardia, impaired intraplacental blood flow (white arrowfor Doppler waveforms) and poor placental blood perfusion (gross pictures) were found in FNAIT fetuses compared to fetuses of non-immune mice at E14.5.bPlacental casts of the um...
FGR was diagnosed by ultrasound when EFW was below the 10th percentile in relation to the gestational age and Doppler abnormalities were found, and/or EFW was below the 3rd percentile. The Fetal Medicine Barcelona (FMB) calculator [26] was used to assess percentiles based on ultrasound EFW, ...
Figure 1. Schematic description of Doppler velocimetry. PSV (peak systolic velocity), VTI (velocity time integral), SAT (systolic acceleration time), SD-DT (systolic deceleration-diastolic time), HB (heartbeat). PSV, peak systolic velocity; VTI, velocity time integral; SAT, systolic acceleration...
Machine learning algorithms had helped to improve prediction in different problems in medicine [23], although the nature of the used models is very diverse. Decision trees [24], support vector machines [24,25,26], adaptative boosting [24], convolutional neural networks [27,28], neuro fuzzy ...
