A<unk>  can typically be diagnosed by taking an appropriate medical history in combination with the use of appropriate imaging techniques such as a plain chest X-ray or CT scan. These imaging techniques can detect<unk>  and pleural thickening that surround the lungs. The presence of a thickened peel with or without calcification are common features of<unk>  when imaged. CT scans can more readily differentiate whether pleural thickening is due to extra fat deposition or true pleural thickening than X-rays. If a<unk>  is severe, the thickening may restrict the lung on the affected side causing a loss of lung volume. Additionally, the mediastinum may be physically shifted toward the affected side. A reduction in the size of one side of the chest (hemithorax) on an X-ray or CT scan of the chest suggests chronic scarring. Signs of the underlying disease causing the<unk>  are also occasionally seen on the X-ray. A CT scan may show features similar to those seen on a plain X-ray. Lung function testing typically demonstrates findings consistent with restrictive lung disease.
