Pelvic Ultrasound Scan: What Can It Show?

Pelvic ultrasound scan

A pelvic ultrasound is an ultrasonic examination of pelvic organs and structures on the subject of pathologies. This ultrasound is based on the echolocation concept – the reception of ultrasonic waves sent and later reflected by different tissues which have distinct acoustic qualities.

It is usually performed to detect one or another anomaly of abdominal cavity organs. If it is an obstetrical ultrasound – to monitor the development of a fetus.

There are two types of the test: abdominal (transabdominal pelvic ultrasound) and vaginal (transvaginal pelvic ultrasound). This procedure is necessary to evaluate the uterus, fallopian tubes, vagina, ovaries, and bladder.

Pelvic ultrasound: What can it show?

  • Uterus: the examination identifies the state, shape, general size of the uterus and allows an evaluation of the uterine muscular walls. Besides, it provides a good way to view such uterine structures as the uterine cavity and endometrium. A non-pregnant woman has a slit-like uterine cavity. The endometrium is a functional internal layer and changes during the menstrual cycle;
  • Ovaries: a physician investigates their position relative to the uterus, their size, the size of the follicles and yellow body. The results also show which menstrual cycle phase it is. If the procedure identifies any mass in the ovaries, the physician thoroughly investigates and describes it as well (shape, structure, size);
  • In addition, an ultrasound is used to view the presence of excess fluid (after the ovule emerges from the ovary there should be a small amount) and tumor masses inside of the pelvic;
  • Besides, the estimation of the uterine and ovarian structure, the exam also allows the physician to evaluate the state of the bladder (if its degree of filling is sufficient).

The benefits of pelvic ultrasound

An ultrasound is a fast-performed, cost-saving and easy procedure. It provides clear results and needs minimal effort during preparation for this test. Such ultrasound is completely safe and painless even for expectant mothers.

The physician will move transducer over the studied area with a little pressure. This usually does not cause any discomfort. The test is completely painless if there is no inflammation process in the pelvic cavity. The examination takes 10-20 minutes, depending on its purpose.

What does a pelvic ultrasound show?

  • Uterine scars and anomalies (can lead to infertility, miscarriage, stillbirth, malposition of the fetus, labor abnormality);
  • Endometriosis: a pathological process characterized by spreading of endometrium beyond the uterine cavity. It can lead to infertility as well;
  • Ovarian cysts;
  • Uterine fibroids (or myoma): a benign tumor in the uterus. A pelvic ultrasound provides a way to examine the quantity, size, and position of myomas. Besides, pelvic ultrasound imaging allows monitoring their development. The diagnostics of fibroids is very important for trying to conceive because it can affect the course of pregnancy;
  • Pregnancy: a pelvic ultrasound detects pregnancy when it is at least 3-4 weeks passed. It is possible to identify an early pregnancy with a transvaginal pelvic ultrasound only if the transducer has high resolution. Ectopic pregnancy is diagnosed at an early stage which makes it possible to save the mother’s health;
  • Intrauterine contraception: it permits to control the process of implantation and removal of an intrauterine contraceptive. An ultrasonic imaging is used to detect its irregular position in the uterus, ingrowth into the uterine wall or prolapse in time;
  • Endometrial polyps;
  • Hyperplasia;
  • Cancer.

What does a pelvic ultrasound show?

Every healthy woman should go through a proactive pelvic ultrasound once every 1-2 years (after the age of 40 – once a year) to eliminate hidden pathologies. It is usually performed during the first phase of menstrual cycle (on the 5th-7th day since the cycle’s beginning).
