A molar pregnancy, also known as a hydatidiform mole, is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus. It falls under the category of gestational trophoblastic diseases. [1] During a molar pregnancy, the uterus contains a growing mass characterized by swollen chorionic villi, resembling clusters of ...
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).
[1] [2] On ultrasound and MRI, theca lutein cysts appear in multiples on ovaries that are enlarged. [3] Theca lutein cysts are associated with gestational trophoblastic disease (molar pregnancy), choriocarcinomas, and multiple gestations. [4] [5] In some cases, these cysts may also be associated with diabetes mellitus and alloimmunisation to Rh-D.
Photos of what pregnancy tissue from early abortions at 5 to 9 weeks looks like have gone viral. ... This is the motion that is seen on ultrasound and that people refer to as a ‘heartbeat ...
GTN often arises after molar pregnancies but can also occur after any gestation including miscarriages and term pregnancies. [6] Although risk factors may impact on the development of the tumor, most do not directly cause of disease. According to some studies, the risk of complete molar pregnancy is highest in women over age 35 and younger than 20.
Gestational choriocarcinoma (GC) is the most aggressive form of trophoblastic tumor; it most commonly arises from certain fertilization defects, such as molar pregnancy, which results in increased level of growth factors and uncontrolled proliferation of trophoblasts in the uterus. [8]
When generating a 3D volume, the ultrasound data can be collected in four common ways by a sonographer: Freehand, which involves tilting the probe and capturing a series of ultrasound images and recording the transducer orientation for each slice. Mechanically, where the internal linear probe tilt is handled by a motor inside the probe.
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
