請幫忙看看肺部CT scan. 幾星期前在這裏問了肺部的XRAY問題後聽老師們建議做的CT scan。 先謝謝！

Study Result Impression 1. Mild air trapping. This can be seen in setting of small airways disease especially if the patient has a smoking history. If the patient is a nonsmoker, this could represent features of nonfibrotic hypersensitivity pneumonitis and correlation for any history of inciting factors/antige exposure is recommended. 2. Moderate coronary artery calcifications, more than expected for the patient's stated age.
