For more detailed imaging, the sonographer may well propose a transvaginal ultrasound scan.
This requires inserting a small ultrasound probe gently in the vagina to obtain clearer photos on the uterus and ovaries.
A transvaginal scan might be specially useful when investigating:
PCOS
Ovarian Pelvic Scan Sheffield cysts
Fibroids
Endometrial abnormalities
Your consent will almost always be asked for prior to this scan is done.
