Illustration of the corrections done in four examples using the GUI contour modification program by an experienced radiologist. (a) and (b) Two cases that have the fibroglandular tissues closely connected to the chest wall muscle. Some part of the chest wall muscle is mistakenly included into the breast region in both cases and they need to be excluded, as “exclusion error.” (c) One part of the fibroglandular tissue connected to the chest wall muscle is identified as chest wall muscle and mistakenly excluded. It needs to be included back into the breast, as “inclusion error.” (d) Parts of fatty tissue on bilateral breasts are wrongly excluded by the chest model. They need to be included back into the breast region, as “inclusion error.”
