Hysteroscopy or ultrasound?

The methods of evaluation of the uterus and in particular of the endometrium are the subject of a heated debate, but only because those who argue are trying to establish one single technique which is all-encompassing and 100% accurate. Such specifications are very hard to identify in any technique and consequently we have to have an open mind as to what the patient needs and what combination of methods are to be used to achieve the diagnostic goal.
