NEW YORK—Thinner multislice CT scans are increasing the effectiveness of lung cancer screening, a German investigator said at the 3rd International Conference on Screening for Lung Cancer. U. Joseph Schoepf, MD, of the Institute of Clinical Radiology, University of Munich, showed images from 1 mm slices achieved with the Siemens Volume Zoom. "Obviously, we use the fastest rotation mode that we have available," he said. "That’s a 500 millisecond rotation. With a collimation of 1 mm, that allows us to cover the entire chest in a single breath-hold of about 20 to 25 seconds."
