The age of start of symptoms was lower in smoker asthma patients. Thoracic HRCT result was reported as normal much more frequently in the smoker asthma group (32% vs. 1%) whereas emphysema (45% vs. 12%) was more prevalent in COPD group. The radiological comparison of smoker asthma and non-smoker asthma groups yielded no difference.Conclusion: Although no innovative method or state-of-the-art technology was used in this retrospective study, it was found that even conventional HRCT might contribute to the differentiation of these two diseases.
