	Obstetric ultrasound -- a comprehensive guide to ultrasound scans in pregnancy
		In the presence of first trimester bleeding, ultrasonography is also indispensible in the early diagnosis of ectopic pregnancies and molar pregnancies.
		Ultrasonography has become indispensible in the localization of the site of the placenta and determining its lower edges, thus making a diagnosis or an exclusion of placenta previa.
		In this situation, ultrasonography is invaluable in determining the number of fetuses, the chorionicity, fetal presentations, evidence of growth retardation and fetal anomaly, the presence of placenta previa, and any suggestion of twin-to-twin transfusion.

	Ultrasonography -- eCureMe.com
		During ultrasonography, a hand-held device called a "transducer" is placed on the area being examined and moved around.
		Real time imaging -- ultrasonography can be used to guide invasive procedures such as biopsy, and to visualize bowel movement and blood flow.
		For best results, before taking ultrasonography, ask if the practice where the scan is being performed is accredited either by the American Institute of Ultrasound in Medicine or the American College of Radiology.

	ULTRASONOGRAPHY
		Ultrasonography provides highly accurate information on the physical characteristics of a goiter, reliably distinguishing solid nodules from those which are cystic or of mixed echogenecity.
		Ultrasonography may be used to monitor the size of solitary thyroid nodules, especially in those patients who are on thyroxine suppressive therapy.
		As the ultrasonography can not differentiate between benign and malignant lesions and although ultrasonography can demonstrate subclinical nodularity and cyst formation, the former is clinically irrelevant and the latter apparent at FNAC, which is used routinely on all patients, the routine use of ultrasonography has been largely abandoned.

	Medical ultrasonography - Wikipedia, the free encyclopedia
		Ultrasonography can be enhanced with Doppler measurements, which employ the Doppler effect to assess whether structures (usually blood) are moving towards or away from the probe.
		This is particularly useful in cardiovascular studies (ultrasonography of the vasculature and heart) and essential in many areas such as determining reverse blood flow in the liver vasculature in portal hypertension.
		Medical ultrasonography was invented in 1953 at Lund University by cardiologist Inge Edler and Carl Hellmuth Hertz, the son of Gustav Ludwig Hertz, who was a graduate student at the department of nuclear physics.

	Encyclopedia: Medical ultrasonography
		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 Pouch of Douglas, and any findings in the pelvis of relevance outsite of pregnancy.
		Obstetrics (from the Latin obstare, to stand by) is the surgical specialty dealing with the care of a woman and her offspring during pregnancy, childbirth and the puerperium (the period shortly after birth).
		B-scan ultrasonography, or B-scan, is a diagnostic test used in ophthalmology to produce a two-dimensional, cross-sectional view of the eye and the orbit.

	Alternative Breast Cancer Treatment
		For example, if a woman has a lump in her breast or a suspicious mammogram, ultrasonography is often used to determine if the problem area is a common fluid-filled cyst or a solid mass of some sort.
		However, ultrasonography is not considered an adequate substitute for screening by mammography, because it is not as good as mammography in identifying small cancers.
		However, ultrasonography is often able to identify early-stage invasive cancers in women who have dense breasts when those cancers are too small to be felt as lumps and are hidden, on mammogram, by milk duct tissue.

	[Clinical Preventive Services] Screening Ultrasonography in Pregnancy (Site not responding. Last check: 2007-10-12)
		Ultrasonography is widely used in pregnancy in the U.S. According to 1992 U.S. natality data, 58% of mothers who had live births received ultrasonography in pregnancy, compared to 48% in 1989.1 The highest rates occurred in white women and those ages 25_39 years.
		For asymptomatic low-risk women, a single scan in the second trimester may be used to estimate gestational age in women with unreliable dates of last menses and to detect multiple gestation and fetal malformations.
		There is no clear evidence of important adverse effects related to screening ultrasonography reported from the published randomized controlled trials, although such effects might be difficult to detect given the small number of ultrasounds (usually one or two per patient) and the fact that the controls in many trials were also scanned, with results concealed.

	Doppler ultrasonography
		Doppler ultrasonography is a non-invasive diagnostic procedure that changes sound waves into an image that can be viewed on a monitor.
		The ultrasound principle is this: when a high-frequency sound is produced and aimed at a target, it will be reflected by its target and the reflected sound can be detected back at its origin.
		During a Doppler ultrasonography procedure the technician will apply a gel to the skin, then place the transducer against the skin at various angles.
