A Pelvic ultrasound is one of the major diagnostic tools used to detect Polycystic Ovarian Syndrome and to image the uterus and ovaries or urinary bladder. Ultrasounds are used during pregnancy to check on the development of the fetus. Men are sometimes given a pelvic ultrasound to check on the health of their bladder and prostate. Polycystic ovary syndrome (PCOS, also known clinically as Stein-Leventhal syndrome), is an endocrine disorder that affects 5–10% of women. ... Female internal reproductive anatomy The uterus or womb is the major female reproductive organ of most mammals, including humans. ... Human female internal reproductive anatomy Ovaries are a part of a female organism that produces eggs. ... The interior of bladder. ... Ultrasound is sound with a frequency greater than the upper limit of human hearing, approximately 20 kilohertz. ... A pregnant woman Human pregnancy refers to the process by which a human female carries a live offspring from implantation until childbirth. ... Fetus at eight weeks A fetus (alternatively foetus or fÅ“tus) is an unborn human offspring from the end of the 8th week of pregnancy (when the major structures have formed) until birth. ... Male Anatomy The prostate is a gland that is part of male mammalian sex organs. ...
There are two methods of performing a pelvic ultrasound - externally or internally. The internal pelvic ultrasound is perfomed either transvaginally (in a woman) or transrectally (for men).
Medical ultrasonography is an ultrasound-based imaging diagnostic technique used to visualize internal organs, their size, structure and their pathological lesions. ... Gynecologic ultrasonography or Gyn sonography refers to the application of medical ultrasonography to the female pelvic organs, specifically the uterus, the ovaries, the Fallopian tubes, as well as the bladder, the culdesac, and any findings in the pelvis of relevance outsite of pregnancy. ...
Ultrasound is sound with a frequency greater than the upper limit of human hearing, approximately 20 kilohertz.
More powerful ultrasound sources may be used to generate local heating in biological tissue, with applications in physical therapy and cancer treatment.
Ultrasound generator/speaker systems are sold with claims that they frighten away rodents and insects, but there is no scientific evidence that the devices work; controlled tests have shown that rodents quickly learn that the speakers are harmless.
Transvaginal ultrasound is generally done early in a pregnancy to detect a suspected ectopic pregnancy and, occasionally, late in pregnancy to determine the location of the placenta or in a high-risk pregnancy to monitor the length of the cervix.
Ultrasound waves cannot pass through bones; therefore, an ultrasound to evaluate the brain cannot be done once the bones of the skull (cranium) have grown together.
Cranial ultrasound may be done to evaluate an infant's large or increasing head size, detect infection in or around the brain (such as from encephalitis or meningitis), or to screen for brain problems that are present from birth (such as congenital hydrocephalus).
