Variation in the determination of follicular diameter: an inter-unit pilot study using an ultrasonic phantom.
Ultrasound operators in assisted reproductive technology units in New South Wales, Australia cooperated in a study that was conducted to assess their ability to measure fixed objects embedded in an ultrasound phantom. The results have demonstrated a large variation ranging between 10 and 25% coefficient of variation on distances between 10 and 32 mm. As ultrasonic imaging is the only component of assisted reproductive technology not currently controlled by an external quality assurance scheme, the authors suggest there may be a need to establish a programme.
