For a female pelvic scan, in most cases, you will be offered a transvaginal (TV or internal) scan as this can often provide greater detail to aid diagnosis in the pelvic region.

The sonographer will place a narrow probe inside your vagina. This probe will have a latex-free cover over it. The probe is then gently moved to allow visualisation of the pelvic organs. The sonographer will discuss this examination with you, should it be required. You will be asked to empty your bladder before this procedure.

The examination can still be undertaken during your period, and will also be offered if you have not been sexually active in line with national guidelines.

If you have had a positive pregnancy test prior to your scan, please contact us on 0203 818 7777

If you are unable to tolerate an internal scan you will be offered a transabdominal scan (TA) instead. Please follow preparation instruction as outlined above.
