Interventions
DIAGNOSTIC_TEST

1. Standard spirometry

Spirometry is performed in two positions (sitting and supine) and three types of breathing (spontaneous, forced and slow).

DIAGNOSTIC_TEST

2. 3D dynamic lung MRI at UTE in prone and supine positions

Dynamic lung MRI is performed for 3D MR spirometry while the subject is lying prone and supine before a reversibility test with salbutamol.

DRUG

3. Reversibility test with salbutamol

Reversibility test with salbutamol administered using a pressurized metered dose bottle and an inhalation chamber at a dosage of 100 μg, 4 times (i.e., 400 μg in total).

DIAGNOSTIC_TEST

4. 3D dynamic lung MRI at UTE in supine and prone position

Dynamic lung MRI is performed for 3D MR spirometry while the subject is lying prone and supine after the bronchodilatator's administration.
