Early Pregnancy Scan

Obstetric ultrasonography , or prenatal ultrasound , is the use of medical ultrasonography in pregnancy , in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus womb. The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus. The International Society of Ultrasound in Obstetrics and Gynecology ISUOG recommends that pregnant women have routine obstetric ultrasounds between 18 weeks’ and 22 weeks’ gestational age the anatomy scan in order to confirm pregnancy dating, to measure the fetus so that growth abnormalities can be recognized quickly later in pregnancy, and to assess for congenital malformations and multiple pregnancies twins, etc. Performing an ultrasound at this early stage of pregnancy can more accurately confirm the timing of the pregnancy, and can also assess for multiple fetuses and major congenital abnormalities at an earlier stage. There is no difference, however, in perinatal death or poor outcomes for infants. Below are useful terms on ultrasound: [4]. In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity.

In early pregnancy, especially before 11 weeks, it is usual to have a trans-vaginal internal scan , where a probe is placed in the vagina. This gives the clearest and most accurate picture in early pregnancy. The person doing the scan spreads a special gel on your lower abdomen below your belly button and above the line of pubic hair.

If you are less than seven weeks pregnant, it’s unlikely to find a heartbeat by a yolk sac or embryo on a repeat scan if a gestational sac is empty on initial scan.

At around seven weeks of your pregnancy, the embryo begins to grow hands and feet. This is when the mother can see her baby for the first time through an ultrasound. This scan is performed for various purposes. Getting an ultrasound done has the following benefits on the baby —. Women who have an irregular menstrual cycle or do not remember their last menstrual period date find it challenging to calculate their due dates.

In such situations, a dating scan to estimate the approximate gestational age of the baby can be helpful in calculating the estimated delivery date.

Obstetric ultrasonography

I am currently 6 weeks pregnant with my second baby. I went for an early scan last Thursday to to rule out an ectopic pregnancy as had been having a few pains. Its not ectopic but the sonographer couldnt find a heartbeat.

At 5 weeks into pregnancy things are so small there is very little to an approximate date, but it isn’t as accurate and measuring the embryo. quite well, but it is not always possible to see a heartbeat at this time. This is why, at Early Life Ultrasound centre we offer early pregnancy scans from 7 weeks.

The pregnancy is calculated based on the average menstrual cycle which is 28 days. The first day of menstrual bleeding marks the first day of the menstrual cycle. Right in the middle of this picture perfect 28 day cycle is when ovulation occurs day 14 of the cycle and roughly 2 days before and after is when you are most fertile. This is why many fertility doctors recommend to have intercourse every 3 days if you really are trying to have a baby because the ovulation may occur a little earlier or later than you may think.

When calculating the weeks of pregnancy we include those two weeks from the first day of the LMP as this is the easiest part of the cycle to notice and to record. We also will enquire about the length of your cycle and whether it is regular or irregular. All of this is helpful in trying to establish the gestation. For example, if your cycle is regular and 33 days long we would expect your ovulation to have occurred later 5 days and an early pregnancy scan will most likely show a baby that measures 5 days less than you were expecting.

Now to answer your question, it may be that you ovulated later in the cycle or have a longer cycle. The other possibility is that unfortunately the pregnancy is not developing as expected at 7 weeks gestation and a follow up scan may reveal a miscarriage.

Early pregnancy roughly spans the first ten weeks of the first trimester. Occasionally, early pregnancy is unintentionally imaged by CT or sometimes MRI is done for some concurrent pathology, and its important to know the imaging findings 3. The earlier in pregnancy a scan is performed, the more accurate the age assignment from crown rump length.

In the early weeks of pregnancy, many women have questions about fetal rump measurements (CRL) to be taken, so that pregnancy dating can be a bit more accurate. or cardiac activity is seen, another ultrasound scan should be done in days. A normal heartbeat at weeks would be beats per minute.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.

Dating scans are usually recommended if there is doubt about the validity of the last menstrual period. By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.

This is because the fetus is growing so quickly that there is a big difference in size from week to week.

What size will my baby be at the time of doing a 7 week ultrasound for pregnancy? The average length of the embryo at 7 weeks ranges between 5mmmm. The average weight is less than 1 gram. Be aware though that every pregnancy is unique and individual factors influence the size of the embryo at this early stage.

A full bladder assists easier passage of ultrasound waves into the pelvis as well. Later on as the pregnancy progresses, a full bladder is not necessary as the enlarging uterus grows. The transducer is placed in the vagina and the sound waves are transmitted via the cervix and directly into the uterus. With this form of scan, it is not necessary for you to have a full bladder.

The sonographer might decide to use this method to achieve the most accurate visualisation. With this form of scan it is not as necessary for you to have a full bladder.
