Lung disease assessment in primary ciliary dyskinesia: a comparison between chest high-field magnetic resonance imaging and high-resolution computed tomography findings

Table 4 Median HRCT and MRI scores of the whole study population and their agreement

	HRCT	MRI	r
Severity of bronchiectasis	2 (0–3)	2 (0–3)	0.87
Severity of peribronchial wall thickening	2 (1–2)	2 (0–2)	1
Extent of bronchiectasis	2 (0–3)	2 (0–3)	0.97
Extent of mucous plugging	2 (0–3)	2 (1–3)	0.94
Extent of sacculations or abscesses	0 (0–1)	0 (0–1)	NA
Generation of bronchial divisions involved (bronchiectasis or plugging)	3*	3*	NA
Severity of bullae	0 (0–3)	0*	NA
Severity of emphysema	0 (0–1)	0 (0–1)	NA
Severity of collapse or consolidation	2 (0–2)	2 (0–2)	1
Total score	12 (6–20)	12 (5–17)	0.95

NA: not applicable (see text).
Values in parentheses are ranges.
* No range values are given because all patients had the same score. For generation of bronchial divisions involved by bronchiectasis or plugging, the same score was attributed in each patient to both HRCT and MRI scans.
