Helical/spiral computed body tomography
Clinical Radiology, 1997 Summary Helical CT has profound implications for routine imaging in the chest and abdomen as well for specialized imaging of hollow organs and blood vessels. The ability to image the chest or abdomen in a single breath and to review overlapping images retrospectively has improved our ability to detect and measure the attenuation of small lesions ...
