Beskrivelse
Inclusion Criteria:
- Male or female, ≥ 40 years old
- COPD as defined by the global Initiative on obstructive lung disease4
- Post-bronchodilator FEV1/FVC < 70% AND post-bronchodilator FEV1 <80%pred as documented in the last 5 years.
- Smoking history of at least 10 pack-years
- At entry in the study experiencing an exacerbation defined as an acute change in the patient 's baseline dyspnea, cough, and/or sputum that is beyond normal day to day variations, and that necessitates the administration or doubling of systemic corticosteroid treatment.
- Patients must be able to understand and complete protocol requirements, instructions, questionnaires and protocol-stated restrictions.
- Written and signed informed consent
Exclusion Criteria:
- Pregnant or lactating females
- Patient diagnosed with asthma
- Patient with pneumonia as defined radiologically at the start of the exacerbation
- Patient with a history of or presence of lung cancer
- Patient with an indication for non-invasive ventilation
- Patient unlikely to comply with the protocol or unable to understand the nature, scope and possible consequences of the study.
- Patient who received any investigational new drug within the last 4 weeks prior to visit 1.

Changes in functional respiratory imaging parameters
Tidsramme: Baseline (= during exacerbation) and after about 6 weeks (= after recovering)
|
The primary objective of this study is to evaluate whether changes in HRCT based airway dimensions and Computational Fluid Dynamic (CFD)-based resistance values correlate with changes in lung function parameters, under the conditions of exacerbation of COPD as well as after recovering from exacerbation.

Changes in patient reported outcome (PRO) measures
Tidsramme: Baseline (= during exacerbation) and after about 6 weeks (= after recovering)
|
The secondary objective is to check if the changes in CFD data actually correlate better with changes in PRO than changes in lung function parameters.

Reproducibility of segmentation
Tidsramme: Within 1 month of visit
|
As tertiary objective the reproducibility of the segmentations done by the centers will be evaluated.
To accomplish reproducible segmentations the multiple centers will be guided to perform accurate segmentations, and bottlenecks in the usage of the program will be identified and resolved in order to simplify it where necessary and possible.
