Comparison of mean CT and UTE MRI CF-specific scores in pediatric patients with CF and control subjects

Subjects	Bronchiectasis	Mucus Plugging	Bronchial Wall Thickening	Consolidation	Ground-Glass Opacity	Air Trapping	Overall
Patients with CF – CT scores (Ttest of CF patients’ CT scores vs. UTE MRI scores)	1.55 ± 2.78 (0.091)	0.41 ± 0.89 (0.11)	2.32 ± 1.81 (0.045)	2.45 ± 1.44 (0.34)	0.50 ± 0.71 (0.42)	2.59 ± 3.12 (0.025)	9.86 ± 7.04 (0.0053)
Patients with CF – UTE MRI Scores (Ttest of UTE MRI Scores of patients with CF vs. control subjects)	0.64 ± 1.27 (0.32)	0.091 ± 0.30(0.33)	0.11 ± 1.32 (0.11)	3.0 ± 1.92 (0.011)	0.32 ± 0.34 (0.70)	0.14 ± 0.32 (0.19)	5.55 ± 3.70 (0.017)
Control subjects – CT scores (Ttest of CT Score of patients with CF vs. control subjects)	0.19 ± 0.56 (0.14)	0.039 ± 0.14 (0.20)	0.039 ± 0.14 (0.0019)	0.46 ± 0.95 (0.0011)	0.039 ± 0.14 (0.057)	0.0 ± 0.0 (0.020)	0.77 ± 1.20 (0.0016)
Control subjects – UTE MRI scores	0.23 ± 0.34	0.0 ± 0.0	0.50 ± 0.77	1.14 ± 0.84	0.41 ± 0.70	0.0 ± 0.0	2.27 ± 1.42

Definition of abbreviations: CF = cystic fibrosis; CT = computed tomography; MRI = magnetic resonance imaging; UTE = ultrashort echo-time.

Data are presented as mean ± SD (P value). Age-matched control subjects generally had lower scores compared with patients with CF.
