greetings. I have had recent breathing broblems (I was diagnosed with moderate COPD due to some asthma symptoms in 2017) following a bronchitis-like illness and the x-ray results stated: Findings: Linear scar versus atelectasis of the left lung base is present. A normal cardiomediastinal silhouette without acute airspace disease, effusion, or pneumothorax is identified. Impression: 1. Negative for acute cardiopulmonary process. I don t understand all of this, especially the term versus concerning atelectasis. Any insight into the meaning of the medical jargon would be very helpful. Thank you.
