HRCT shows widened, damaged airways in bronchiectasis. Learn why it is advised for long-term cough with sputum, what causes it and how it is managed.
Bronchiectasis is a long-term condition in which the airways of the lungs become widened and scarred, so mucus collects and infections keep recurring. HRCT chest is the best test to diagnose it. It shows widened airways, thick walls and mucus plugs, and helps find the cause and plan treatment.
What Causes Bronchiectasis?
- Past severe infection such as tuberculosis, whooping cough or pneumonia
- Cystic fibrosis and primary ciliary dyskinesia
- Immune deficiency
- Allergic fungal disease (ABPA) in asthma
- Blockage of an airway by a foreign body or tumour
- Sometimes no cause is found
See CT chest for tuberculosis.
Symptoms That Should Prompt a Scan
Daily cough with sputum for months, repeated chest infections, coughing blood, breathlessness, tiredness and wheeze. A chest X-ray may look normal or only slightly abnormal, so HRCT is needed to confirm the diagnosis. See HRCT chest.

- Blood tests, including immunoglobulins and allergy markers
- Spirometry to measure airflow
- Sweat test or genetic tests in selected patients
Treatment Overview
Treatment aims to clear mucus, control infection and prevent flare-ups. It includes daily airway clearance (chest physiotherapy, breathing devices), saline or other nebulisers, antibiotics for flare-ups and sometimes long-term antibiotics, vaccines and treating the underlying cause. Surgery is rare and used for localised disease with repeated bleeding.
Preparation and Safety
No fasting is needed for a plain HRCT. Bring old X-rays and sputum reports. Practise a clear deep breath and short breath-hold. Contrast is rarely required. The dose is lower than a full contrast CT. See CT scan preparation.
A Practical Example
Poonam, 40, had TB as a child and now coughs up sputum daily with repeated chest infections. HRCT shows widened airways in the right upper lobe. Her chest physician starts airway clearance exercises, saline nebulisation and a vaccination plan, and teaches her to recognise early flare-ups. Her hospital visits fall over the year.
After the Scan and Next Steps
Take the HRCT report to a chest physician. Learn your airway clearance routine from a physiotherapist and practise it daily. Drink water, stay active, take vaccines and avoid smoke. Start treatment early for increased sputum, fever, breathlessness or blood in sputum, and get follow-up lung function tests.
Questions to Ask Your Doctor
- What caused my bronchiectasis?
- Which airway clearance technique suits me?
- Do I need long-term antibiotics?
- Which vaccines should I take?
Common Mistakes to Avoid
- Skipping daily airway clearance when feeling well.
- Taking antibiotics without a sputum test.
- Ignoring blood in sputum.
Booking, Timing and Report
Most CT scans can be booked on the same day, and the visit takes 20 to 40 minutes. Carry your prescription, old scans and a recent creatinine report if contrast is planned. Reports are usually ready within 24 hours, and images can be provided on a CD or digital link for your doctor.
Key Facts at a Glance
- HRCT is the best test for bronchiectasis
- Daily airway clearance is the foundation of treatment
- Flare-ups need early antibiotics after a sputum test
- Vaccines and smoke avoidance protect the lungs
Understanding Your Report
The report may grade bronchiectasis as cylindrical, varicose or cystic, and name the lobes affected. Lower lobe disease is often linked to past infections, and upper lobe disease to TB or fungal infection. It may also mention mucus plugs, air trapping or enlarged lymph nodes. Ask your chest physician what these findings mean for your treatment.
Daily Routine That Helps
Start the day with airway clearance, such as active cycle of breathing, huffing and postural drainage taught by a physiotherapist. Use nebulised saline if advised, drink plenty of water, and repeat the routine in the evening. Exercise daily, since walking helps move mucus. Keep your vaccinations up to date and avoid smoke and dust.
