Concerns Regarding Early Fetal Development

American Institute of Ultrasound in Medicine consensus report on potential bioeffects of diagnostic ultrasound. National Council on Radiation Protection and Measurements. Criteria Based on All Known Mechanisms. National Council on Radiation Protection and Measurements; Effective prenatal diagnosis relies on a high standard of imaging. Several national and international bodies have described standards for imaging in the first, second, and third trimester of pregnancy. However, many experts in the field advocate the use of additional views to improve diagnostic performance.

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. The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise in the fetus.

References “The technology of prenatal diagnosis is usually presented to us as a solution, but it brings with it problems of its own If you’ve already read it, you may want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them.

Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing. However, since they may be at a somewhat increased risk for problems like neural tube defects, they also face greater pressure than others to have these prenatal tests, even though the tests are often difficult to interpret.

It is further designed to address the special concerns that large women might have in taking these tests their fears, any special equipment or techniques that might be helpful, the controversies over interpretation of results, whether large women have a higher rate of so-called ‘false-positives’ on certain tests and why, etc. It’s important to remember that discussing prenatal tests can be simple or incredibly complicated, depending on the degree of detail that is needed and the point under discussion.

This FAQ is NOT intended to be a full explanation of all the intricacies of taking and interpreting various prenatal tests, but rather a discussion of them as they pertain to large women. A brief description of the test, its purpose, and the procedures used are given for each test, but the majority of the information is about the specifics of large women and the test.

If you need more detail about statistics, interpretation of results, rates of ‘false-positives’, etc. It is also important to realize that most women take these tests without fully considering all of the implications of the test.

The first trimester is months one, two, and three of your pregnancy. Below are scan pictures taken during the early weeks of pregnancy. Measurements taken at these early scans will help to; confirm a pregnancy, date the pregnancy and to see any problems that may occur in the pregnancy low lying placenta, twins etc. Scans in early pregnancy are usually performed in the first trimester around 12 weeks.

You may have a earlier scan, if you are experiencing pain or bleeding for example or unsure of LMP dates. Transabdominal ultrasound TAU and also the transvaginal ultrasound TVU are valuable diagnostic tools in obstetrics and gynecology. Transabdominal ultrasound will provide a panoramic view of the abdomen and pelvis and is noninvasive, whereas transvaginal ultrasound provides a more limited pelvic view and requires insertion of a probe into the vagina. Transabdominal ultrasound cannot reliably diagnose pregnancies that are less than 6 weeks gestation.

Prompt diagnosis made possible by transvaginal ultrasound can, therefore, result in earlier treatment. It is recommended that all pregnant women have a scan in the first trimester, to establish the date when the baby is due, check the number of babies also the position of the placenta.

Lisa I have not been diagnosed as having any kind of cancer, yet the first GYN ontological surgeon I visited recommended a total hysterectomy, even though my CA score was 7. I sought a second opinion and got a very different suggestion – a laparoscopic removal of my ovaries and Fallopian tubes. Everyone is so scared of ovarian and cervical cancer, and rightly so, as they are most often not discovered until they are rather advanced. However, my first opinion surgeon seemed to me to be jumping the gun.

My second opinion doctor still must look at the sonograms and MRI before her final opinion, which she should be giving me this week first week of One approach is to take everything out to prevent having to operate again in the future. The other approach is to take out only what seems threatening. It seems there really is no clear way to go to me.

First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby.

Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester.

My OB, who was very supportive of me throughout this pregnancy never a mention of my weight, very supportive of my desire to VBAC , was ready to induce when I finally went into spontaneous labor after a couple of nights of prodromal labor.

The truth is that it is very difficult, if not impossible, to tell if you have a blighted ovum just by your symptoms and really the only way to know for sure is by having the ultrasound scan done so that they can look at your uterus and determine if there is an embryo present or not or just the gestational sac.

I have to make a decision today as to what I am going to do- keeping going or not. I am hoping to hear from any woman who drank as heavily as I did before she knew she was pregnant and then went on to have the baby. When I was 28 days 4 weeks since my last period, I drank two bottles of wine standard ML size in one night.

The next night, I had 3 drinks 1 beer, 2 glasses of wine , and the night after, I had beers. I was also drinking earlier that month, usually a glass of wine here or there. What really worries me is the binge drinking, the heavy drinking, the night of 2 bottles of wine.

HCG Levels for normal Pregnancy. The quantitative maternal serum beta HCG peaks at approximately 10 weeks and then reduces. It will be difficult to see if the mother has a retroverted uterus or fibroids. The GS is an echogenic ring surrounding an anechoic centre. An ectopic pregnancy will appear the smae but it will not be within the endometrial cavity. Gestational sac size should be determined by measuring the mean of three diameters.

These differences rarely effect gestational age dating by more than a day or two. The following image is using a transvaginal approach the gestational sac can be seen during week Yolk Sac Only seen. The yolk sac will be visible before a clearly definable embryonic pole. Mean Sac Diameter measurement is used to determine gestational age before a Crown Rump length can be clearly measured.

The more accurate predictors, eg, LMP, should need no further corroboration during the course of pregnancy as long as the clinical course remains congruent with gestational length. Less accurate variables, eg, first fetal heart tones or fundal height need further confirmation in the absence of a useful menstrual history. New research is presented on uterine height correlation with gestational age, within the context of related research.

Since discrepant uterine size is the most commonly cited reason for ordering ultrasound during pregnancy, this variable was examined in terms of its correlation to gestational age in an effort to define the discrepancy so often cited.
