1. Objective To find suitable critical value of fetal nuchal translucency (NT) by ultrasonic testing.

2. Nuchal scan is performed between 11 and 14 weeks of gestation, because the accuracy is best in this period.

3. It is important to distinguish the nuchal lucency from the underlying amnionic membrane.

4. Objective:To review developments of acupuncture on nuchal region(AONR)in recent 10 years and put forward references for the further scientific research and clinical practice.

5. The nuchal scan helps doctors to estimate the risk of the fetus having Down syndrome or other defects more accurately than by maternal age alone.

6. Objective:To evaluate effect of nuchal cord on the delivery pattern.

7. Conclusions The diagnostic value of CDFI for nuchal cord correlates with the interval between the CDFI and delivery.

8. Methods Fetal nuchal translucency thickness was measured between 11-14 weeks of gestation with serial follow-up ultrasound examinations.

9. Nuchal pad of skin This is the fold of skin at the back of the neck.

10. A lumbar puncture is necessary for those who are severely ill or in those who show any suggestion of nuchal rigidity.

11. AIM: To observe the fine anatomic structure and the structural status of the human nuchal ligament.

11. is a online sentence dictionary, on which you can find good sentences for a large number of words.

12. The adoption of P45 sheet plastination technique makes the complete appearance of the fine anatomic structure of human nuchal ligament more obvious.

13. Results:Symptoms such as nausea, vomiting, dizziness and dystaxia were common in this group of patients, and headache and nuchal rigidity were found in 51.6% and 32.3% patients respectively.

14. Clinical manifestations were mainly such symptoms as fever, convulsion, vomitting, spiritlessness, gaze, bulging quadrangular fontanel and nuchal vigidity. The pathological reflex was positive.

15. Objective: To determine the diagnosis, surveillance and delivery method for pregnancies with nuchal cord and cephalic presentation.

16. So after this time any abnormalities causing fluid accumulation may seem to correct themselves and can thus go undetected by nuchal scanning.

17. The results suggested that the nature of the meniscoid structures was the synovial fold and its entrapment or breakage might be one of the causes for nuchal pain.

18. Ten tentacles as long or longer than its body stick out of its head, along with six pairs of curved nuchal organs that allow the squidworm to taste and smell underwater.

19. Methods: The animal model was established in composite factors, with injecting scopolamine into subcutaneous part of nuchal region of rat, to block the cholinergic receptor.

20. Further, other, non-trisomic abnormalities may also demonstrate an enlarged nuchal transparency.

21. In foetuses with a normal number of chromosomes, a thicker nuchal translucency is associated with other fetal defects and genetic syndromes.

22. Methods 67pregnant women with gestational age of 10-14 weeks were measured for nuchal translucency thickness by ultrasonic testing.
