How to diagnose Vasa Previa?

Transvaginal scan combined with a color doppler is the best method to diagnose Vasa Previa. In this method, the transducer which produces ultrasound waves is fitted inside the vagina of the women and will be lubricated and covered with a sheath. This method is more accurate than using abdominal scan because it allows the sonographer to see the area of interest more accurately and clearly. If we view the image on grayscale, it is very difficult to read, so the color doppler enables the technician to see the speed and direction of blood flow.
