The tones in which the opacifies ore seen are recorded. Each lung is dniJed into three tones'--upper, middle and lower. : The category of profusion is based on the assessment of the concentration (profusion) of opacities in the affected tones. . The standard films define-the mid-categories. Category 0 small irregular opacities absent nr less profuse than in category 1. Category 1 small irregular opacities definitely present but few in number. The normal lung markings are usually visible. Categoiy 2 small irregular opacities numerous. The normal lung markings are usually partly obscured. Category 3 - ^mall irregular opacities 'try numerous. The normal lung markings are usually totally obscured. As the opacities are irregular, the dimensions im J for rounded opacities cannot be used, but they can h< roughly divided info three types, i fine irregular or linear opacities. \ 1 medium irregular opacities.
