BACKGROUND: The aim of this article is to compare two CT pulmonary scoring systems utilized in the assessment of patients with primary ciliary dyskinesia: the Bhalla and Magnin scores. Both scores have a well-known correlation with pulmonary function tests.
METHODS: A cohort of 54 patients with primary ciliary dyskinesia was evaluated with both CT scores by three radiologists, each with a different amount of experience (1, 5 and 10 years) in reporting lung CTs. The scoring time was measured with a stopwatch. To evaluate the inter-reader agreement, the intraclass correlation coefficient was calculated. Pearson correlation was used to assess the relation between the two CT scores for each reader. Paired sample t-test was utilized in evaluating scoring time with both the Bhalla and the Magnin scores.
RESULTS: The intraclass correlation coefficients (ICC) for the Bhalla and Magnin scores were 0.84 (95% CI: 0.743-0.93), and 0.748 (95% CI: 0.637-0.834). The CT scores were strongly correlated for each reader (rs>0.8; P<0.001). The Magnin scoring time was significantly different from the Bhalla score and required more time (mean 23±22%).
CONCLUSIONS: The Bhalla score has a higher inter-reader reliability and requires less scoring time than the Magnin Score.
