Transvaginal Scans

Special probes have been designed to allow ultrasound scanning to be done with the probe placed in the vagina of the mother. Performing ultrasound scnas using this method usually provides better images and more information in patients who are obese and / or in early stages of pregnancy. The better images are the result of the scan head’s closer proximity to the uterus and the higher frequency used in the transducer array resulting in higher resolving power. Foetal cardiac pulsation can be clearly observed as early as six weeks of gestation.

Vaginal scans are becoming indipensible in the early diagnosis of ectopic pregnancies. An increasing number of foetal abnormalities are also being diagnosed during the first trimester using the vaginal scan. Transvaginal scans are also useful in the second trimester in the diagnosis of congential abnormalities.
