When Can You See Placenta on Ultrasound?
The placenta plays a vital role in supporting your baby’s development throughout pregnancy. This temporary organ is responsible for supplying oxygen and nutrients to the growing fetus while also removing waste products. It is an essential component of a healthy pregnancy, and its proper functioning is closely monitored through pregnancy ultrasound imaging. During an ultrasound, healthcare providers assess the placenta’s position, structure, and overall health to ensure both mother and baby are thriving. But when can you see placenta on ultrasound? Let’s explore the timeline of placental development and what you can expect during your ultrasound appointments.
When Can You First See the Placenta on Ultrasound?
In the early stages of pregnancy, the placenta begins to form shortly after implantation. However, it is typically not visible on ultrasound until around 10 to 12 weeks of gestation. At this point, the developing placenta appears as a thickened area near the gestational sac, though it may still be in the early phases of development. As the pregnancy progresses, healthcare providers start monitoring its position and attachment to the uterine wall to ensure everything is progressing normally.

By the second trimester, between weeks 13 and 26, the placenta becomes more developed and distinguishable on ultrasound scans. At this stage, the organ has established its full function of supporting fetal growth. A detailed 20-week anatomy scan is often performed to evaluate placental placement, ensuring that it is not covering the cervix (a condition known as placenta previa) and confirming that proper blood flow is being maintained. This scan is crucial in assessing the baby’s overall health and ensuring the placenta is in the right position for a safe delivery.
What to Expect During an Ultrasound Exam
Ultrasound exams are a standard part of prenatal care and provide crucial information about the placenta and fetus. These exams are completely safe and non-invasive, using sound waves to create images of the baby and placenta. When examining the placenta, the healthcare provider may perform either a transabdominal or transvaginal ultrasound, depending on how far along the pregnancy is and the clarity of the images required.
A transabdominal ultrasound is the most common type performed in the second and third trimesters. This method involves applying gel on the abdomen and moving a handheld probe across the belly to capture images. This scan allows for a clear view of the placenta’s location and development. In some cases, particularly in early pregnancy or when a more detailed view is necessary, a transvaginal ultrasound may be conducted. This method involves inserting a small probe into the vagina to get a closer look at the developing placenta and its attachment to the uterus.
During the ultrasound, the provider will carefully examine the placenta’s location to determine whether it is anterior (positioned at the front of the uterus), posterior (at the back), fundal (at the top), or lateral (on the sides). Additionally, they will assess placental maturity and thickness, blood flow circulation, and look for any potential abnormalities, such as placenta previa or placental abruption, which could impact the pregnancy.
Why Seeing the Placenta on Ultrasound is Important
The placenta’s health is a key factor in a successful pregnancy, making regular ultrasound monitoring essential. When healthcare providers can clearly visualize the placenta on an ultrasound, they can confirm that it is properly attached to the uterine wall and functioning as it should. One of the most important aspects of these assessments is ruling out potential complications such as placenta previa, where the placenta covers the cervix, or placental insufficiency, which occurs when the placenta does not provide adequate nutrients and oxygen to the baby.
Ensuring that the placenta is supporting proper oxygen and nutrient transfer is crucial for fetal development. If any irregularities are detected, additional monitoring or interventions may be necessary to promote a healthy pregnancy. As the third trimester approaches, ultrasounds may be used to evaluate conditions such as placenta accreta, a serious complication in which the placenta grows too deeply into the uterine wall. Identifying such concerns early allows for better management and preparation for delivery, ensuring the safest possible outcome for both mother and baby.
Final Thoughts: When Can You See Placenta on Ultrasound?
In summary, the placenta typically becomes visible on ultrasound around 10 to 12 weeks of pregnancy, with clearer and more detailed assessments possible by the second trimester. Routine ultrasounds play an essential role in ensuring that the placenta is developing correctly, reducing the risk of complications and supporting a healthy pregnancy. By monitoring placental function throughout pregnancy ultrasound, healthcare providers can make informed decisions that contribute to the well-being of both mother and baby.
