Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Device for both vaginal ultrasonography and abdominal ultrasonography Transvaginal ultrasonography to check the location of an intrauterine device (IUD). The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically ...
We all might be aware of ultrasounds from movies or TV shows, but not everybody knows that sonograms can actually be helpful for a lot more things besides pregnancy, whether that be looking at a ...
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
It is preferred over abdominal ultrasonography in the diagnosis of ectopic pregnancy. [2] It also can be used to evaluate patients with post-menopausal bleeding. [3] The finding on transvaginal ultrasound of a thin endometrial lining gives the physician a 99% negative predictive value that the patient does not have endometrial cancer. [3]

Both abdominal and vaginal ultrasound may be used, but vaginal ultrasound allows for earlier visualization of the pregnancy. With obstetric ultrasonography the gestational sac (intrauterine fluid collection) can be visualized at 4.5 to 5 weeks gestation , the yolk sac at 5 to 6 weeks gestation, and fetal pole at 5.5 to 6 weeks gestation.
