A gynaecological ultrasound is a diagnostic test used to view the pelvic organs (uterus or womb, ovaries, bladder and rectum or final portion of the large intestine) using an ultrasound probe placed inside the vagina (transvaginal).
A transvaginal probe allows the internal genitalia to be examined very thoroughly, as it comes very close to the area. Furthermore, better resolution is achieved transvaginally than with an abdominal probe (like those placed on the belly during pregnancy).
This type of scan uses ultrasound to produce an image. It does not emit any radiation. This means as many ultrasounds as necessary can be performed without having any negative effect on the patient.
In addition, it is a dynamic test: it is interpreted in real time, as it is performed. It allows the movement of the organs and the relationship between them to be observed (whether or not they are attached, for example), as well as allowing painful areas to be identified.
