Why Do They Measure The Mca In Maternal Fetal Ultrasound
When you subtract 2 weeks from the ga provided by an ultrasound, does that give you the estimated fertilisation age or the estimated fetal age?
Yes: When estimating gestational age by using an ultrasound scan, 2 weeks are added to the fetal age (the fetal age is the fertilisation age). ...Read more
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more
Problem with baby: Blood flow in the mca (middle cerebral artery) may be abnormal if a baby is not getting enough oxygen, either because it has anemia so that it's blood cannot carry enough oxygen, or because it is not getting enough oxygen from the placenta. If your baby is not growing well, or if you have an infection or problem that might be causing anemia, your doctor may look at the baby's mca with ultrasound. ...Read moreSee 1 more doctor answer
Safe fetal imaging.: Fetal ultrasound is an amazing and safe imaging method employing the piezoelectric properties of quartz crystals to convert electrical current to mechanical vibrations; this creates ultra-high frequency sound waves that can penetrate inside the pregnant woman's body and bounce off different structures with variable characteristics. A computer then processes the feedback signal to image the fetus! ...Read moreSee 1 more doctor answer
New computer softwar: New computer software allows for the individual planes acquired during regular prenatal ultrasound scanning to be collated, manipulated and illustrated in a three-dimensional fashion for the uninitiated couples to be able to effortlessly visualize their unborn baby. It provides few/no significant advantage over traditional 2d prenatal ultrasound for the experienced physician/sonographer. ...Read moreSee 1 more doctor answer
A lot of details.: Fetal gender, anatomy in detail (including brain, heart, spine, kidneys, extremities), amniotic fluid volume, due date estimation within 10 days of actual date, cervical and uterine anomaly detection, placental location and pathology. It is a very cost-effective test for any pregnancy and should be universally performed. ...Read moreSee 1 more doctor answer
Heart defects: Tetralogy of fallot, a heart defect, can be difficult to diagnose prenatally. The heart is very small in a developing baby, and specific images must be obtained to make that diagnosis. If the baby is in a bad position, or the mother is obese, or the doctor doesn't have a lot of experience diagnosing heart defects in a fetus, tof can be missed. ...Read moreSee 1 more doctor answer
Some say that 12wk fetal ultrasound measurements can be off by 2wks, but some say only +\-5 days. Which is it?
Fetal Ultrasound Err: The usual figure cited is +|- two weeks for us performed after 12 weeks: http://www.Newbirthcompany.Com/estimated-due-dates/. There are better measurements (such as fetal crown-rump length) that are more accurate as the weeks go by. Don't worry - your obstetrician will be able to "nail down" a more accurate due date in the weeks ahead! ...Read moreSee 2 more doctor answers
