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 ]
A blighted ovum is a pregnancy in which the embryo is reabsorbed or never develops at all. [1] In a normal pregnancy, an embryo would be visible on an ultrasound by six weeks after the woman's last menstrual period. [2] Anembryonic gestation is one of the causes of miscarriage of a pregnancy and accounts for roughly half of first-trimester ...
Gynecologic ultrasonography or gynecologic sonography refers to the application of medical ultrasonography to the female pelvic organs (specifically the uterus, the ovaries, and the fallopian tubes) as well as the bladder, the adnexa, and the recto-uterine pouch. The procedure may lead to other medically relevant findings in the pelvis.This ...
Transabdominal ultrasonography – Ultrasound is performed across the abdominal wall or through the abdominal cavity; In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity. Fortunately, gestational sac, yolk sac and embryo are surrounded by hyperechoic (brighter) body tissues.
An ovarian pregnancy can be mistaken for a tubal pregnancy or a hemorrhagic ovarian cyst or corpus luteum prior to surgery. [8] Sometimes, only the presence of trophoblastic tissue during the histologic examination of material of a bleeding ovarian cyst shows that an ovarian pregnancy was the cause of the bleeding.
To diagnose the rare primary abdominal pregnancy, Studdiford's criteria need to be fulfilled: tubes and ovaries should be normal, there is no abnormal connection between the uterus and the abdominal cavity, and the pregnancy is related solely to the peritoneal surface without signs that there was a tubal pregnancy first.
A transvaginal ultrasound is inserted into the vagina and manually positioned to visualize the uterus, fallopian tubes, and ovaries. Once images have been captured, the ultrasound probe and catheter are removed. The contrast agent used during the study may either spill outside of the vagina or become absorbed. [18]
As ovarian reserve and fertility decline with age, there is also a parallel increase in pregnancy failure and meiotic errors resulting in chromosomally abnormal conceptions. The ovarian reserve and fertility perform optimally around 20–30 years of age. [ 18 ]
