Table 3 Rosemont consensus definitions

Rank	Features		Definition	Location
	Parenchymal features
1	Major A	Hyperechoic foci with shadowing	Echogenic structures ≥ 2 mm in length and width that shadow	Body and tail only
2	Major B	Lobularity with honeycombing	Well-circumscribed, ≥ 5 mm structures with enhancing rims and relatively echo-poor centers, with ≥ 3 lobules	Body and tail only
	Minor	Lobularity with honeycombing	Well-circumscribed, ≥ 5 mm structures with enhancing rims and relatively echo-poor centers, with non-contiguous lobules	Body and tail only
3	Minor	Hyperechoic foci without shadowing	Echogenic structures ≥ 2 mm in length and width with no shadowing	Body and tail only
4	Minor	Cysts	Anechoic, rounded/elliptical structures with or without septations	Head, body and tail only
5	Minor	Stranding	Hyperechoic lines ≥ 3 mm in length in at least two different directions with respect to the imaged plane	Body and tail only
	Ductal features
1	Major A	MPD calculi	Echogenic structures within the MPD with acoustic shadowing	Head, body and tail only
2	Minor	Irregularity of MPD contour	Uneven or irregular outline and ectatic course	Body and tail only
3	Minor	Dilated side branches	3 or more tubular anechoic structures each measuring ≥ 1 mm in width, budding from MPD	Body and tail only
4	Minor	MPD dilation	≥ 3.5 mm in body or > 1.5 mm in tail	Body and tail only
5	Minor	Hyperechoic duct margin	Echogenic, distinct structure greater than 50%of the entire MPD	Body and tail only
