Underestimation of gestational age by conventional crown-rump length growth curves. Reprinted with permission of American College of Obstetricians and Gynecologists Variations in the measurement of CRL can be attributed to differences in fetal growth patterns. Such differences are related to factors similar to those that influence birth weight curves, including maternal age and parity, prepregnancy maternal weight, geographic location, and population characteristics.
These include incorporation of the yolk sac or lower limbs in the CRL measurement, excessive curling or extension of the fetus, and tangential section of the trunk. The biparietal diameter BPD is one of the most commonly measured parameters in the fetus. Campbell was the first investigator to link fetal BPD to gestational age 20 ; however, since this original report, numerous publications on this subject have appeared in the literature.
The BPD is imaged in the transaxial plane of the fetal head at a level depicting thalami in the midline, equidistant from the temporoparietal bones and usually the cavum septum pellucidum anteriorly Fig. Transaxial image of the fetal head for biparietal diameter and head circumference measurements. Ultrasound image with biparietal diameter measurement between the solid arrows, outer edge to inner edge and fronto-occipital diameter measurement between the open arrows.
The head circumference may be calculated using these diameters or measured directly. Diagram of the transaxial ultrasound image of the fetal head at the level of the thalami large arrows , midline falx curved arrow , and cavum septi pellucidi open arrow.
Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.

History[ edit ] Neuroscience and the law have interacted over a long history, but interest spiked in the late s. After the term neurolaw was first coined by Sherrod J. Taylor in ,  scholars from both fields began to network through presentations and dialogs. This led to an increasing pull to publish books, articles, and other literature.
The Gruter Institute for Law and Behavioral Research and the Dana Foundation were the first groups to provide funding for the new interdisciplinary field. Parallel to the expansion of neurolaw, an emergence of ethics specifically regarding neuroscience was developing as well. The intersection of neurolaw and ethics was able to be better scrutinized by the initiation of the Law and Neuroscience Project in The initiative sustained forty projects addressing a multitude of issues, including experimental and theoretical data that will provide further evidence as to how neuroscience may eventually shape the law.
Sherrod Taylor in Brain and Spinal Cord Injury , was used as a resource for attorneys to properly introduce medical jargon into the courtroom and to further develop the implications of neuroscience on litigation. In addition, Taylor explained the consequences of Daubert v. Crime prediction[ edit ] Behavioral testing and neuroimaging evidence offer a potentially accurate method of predicting human behavior.
