NUCHAL TRANSLUCENCY

The scoring method includes:

An assessment of whether an image is interpretable (i.e. overall is it an appropriate image on which to measure the nuchal translucency?)
Each image is then assessed individually on the following:

	Five major criteria	Two minor criteria
	Sagittal section Caliper placement Head position Amnion Image size	Skin line Horizontal to the screen

The major criteria are given a score of either two (2) or zero (0) points depending on whether the criteria are fulfilled.

The minor criteria are given a score of either one (1) or zero (0) points depending on whether the criteria are fulfilled.

The scores for each criterion are then added up to provide a total for each individual image.

A total score of 80 per cent = a pass.

If a candiate scores less than 80 per cent, a re-submission of images is required. See logbook re-submission requirements

If the image is considered un-interpretable, it will not be assessed and will score zero (0).
