Comment: Dr. Wheeler is a world class expert in Occupational Lung Disease and recommends 3-5 mm thick sections at lung and soft tissue windows with standard algorithm followed by nine .75 mm HRCT scan with HRCT algorithm (80 Kernel) spaced from the aortic arch through the lung bases. Both supine and prone images should be done.
