Device for both vaginal and abdominal ultrasonography. Vaginal ultrasonography is a medical ultrasonography that applies an ultrasound transducer (or "probe") in the vagina to visualize organs within the pelvic cavity. It is also called transvaginal ultrasonography because the ultrasound waves go across the vaginal wall to study tissues beyond it.
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 designed vaginal transducer. Transvaginal imaging utilizes a higher frequency imaging, which gives better ...
Most ultrasound examination is done using a transducer on the surface of the body, but improved visualization is often possible if a transducer can be placed inside the body. For this purpose, special-use transducers, including transvaginal , endorectal, and transesophageal transducers are commonly employed.

An ultrasound showing a gestational sac with fetal heart in the fallopian tube has a very high specificity of ectopic pregnancy. It involves a long, thin transducer, covered with the conducting gel and a plastic/latex sheath and inserted into the vagina. [33] Transvaginal ultrasonography has a sensitivity of at least 90% for ectopic pregnancy. [5]
