Chrispin-Norman scoring system for cystic fibrosis

Last revised by Yuranga Weerakkody on 25 May 2017

The Chrispin-Norman score is used to provide a summative assessment of structural lung changes in patients with cystic fibrosis on plain chest radiographs.

It is useful to monitor disease progression or treatment response and can be used to compare between different patients in research studies.

It is usually calculated on the basis of frontal and lateral chest radiographs, although some authors have advocated doing away with the latter 1. There is a maximum modified Chrispin-Norman score of 38 based on the presence of features detailed below 2.
