Asthma Management Handbook

Imaging in diagnosis in adults

Recommendations

Consider arranging chest X-ray if there are respiratory symptoms that are not explained by asthma or as otherwise indicated to investigate the possibility of other conditions (e.g. pneumonia, cancer).

How this recommendation was developed

Consensus

Based on clinical experience and expert opinion (informed by evidence, where available).

Do not routinely order chest X-ray in all patients with suspected asthma, because it is not a diagnostic test for ruling asthma in or out.

Other diagnostic tests in adults

For patients with incompletely reversible airflow limitation, a careful history will often clarify which investigation is most appropriate. Lung volume tests and diffusing capacity tests may be helpful to identify emphysema or pulmonary fibrosis. High-resolution computed tomography is useful if bronchiectasis is suspected.
