Overview

Prospective study demonstrates 0.55 T MRI achieves higher disease detection and reader agreement than chest radiography in cystic fibrosis, suggesting a feasible radiation-free monitoring option.

Key Points

To evaluate the feasibility of contemporary low-field 0.55 T MRI as a radiation-free alternative to chest radiography for monitoring lung disease in cystic fibrosis.
Prospectively evaluated 28 same-day examinations in 22 individuals with cystic fibrosis (mean age 13 ± 5 years) comparing 0.55 T MRI and chest radiography (CR).
Three independent raters scored disease severity using the MRI CF score and an expanded 6-zone modified Chrispin–Norman score.
Analyzed average intermodality score differences, correlations with forced expiratory volume (FEV1), and interobserver reliability using Wilcoxon tests and intraclass correlation coefficients (ICC).
MRI yielded significantly higher global disease scores (median 8.2 vs. 6.7, p = 0.002) and higher centrilobular opacity scores (p = 0.005, adjusted p = 0.03) than CR.
Both modalities correlated inversely with FEV1 (p < 0.001) without a statistically significant modality-by-FEV1 interaction effect (p = 0.08).
Interobserver agreement was significantly greater for MRI (ICC = 0.93) than CR (ICC = 0.82), with an absolute difference of 0.12 (95% bootstrap CI, 0.06 to 0.18).
