Gynaecological Ultrasound Felipe Moretti, MD Griff Jones, MD, FRCS Assistant Professor – UOttawa Maternal Fetal Medicine Division
Basic physics Gynaecology
Ultrasound used for medical purposes is from one MHz (one million cycles per second) to 20 MHz.
Higher frequency wave assesses the object more often in any given time period. This results in more information and allows sharper images
If each wave represents a path, the walker uses the same energy to reach point X. Low frequency waves penetrate deeper into the tissues than high frequency waves
Summary Low frequency sound waves can penetrate more deeply but have less definition than high frequency waves The farther something is away from the probe, the worse the resolution
In OB GYN Ultrasound – – We use low frequency probes for abdominal scanning – We use high frequency probes for transvaginal scanning
Gyne Ultrasound Assess: Uterine pathologies (ex. Fibroids); Endometrial pathologies (ex.polyps); Ovarian pathologies (cysts)
Endometrium changes Throughout the cycle
Anteverted uterus with follicular endometrium Retroverted uterus with secretory endometrium
Trans-abdominal Ovarian Scan
Transvaginal Ovarian Scan
Depth of penetration was not an issue here. But the improved resolution due to the higher frequency of the TV probe shows ovarian substance and allows a diagnosis of polycystic ovaries Transabdominal Transvaginal
Ovarian appearance changes throughout the menstrual cycle
resolved 2 weeks later
