| Popis: | The objective of this study was to compare the quality of conventional and helical computed tomography (CT) images in children unable to breath-hold. Sixteen patients (age range 1.1–7.5 years) underwent both conventional and helical chest CT on a General Electric HiSpeed Advantage scanner at a mean study interval of 3.8 months. Conventional 0.6-s scans were reconstructed with standard algorithm while 1.0-s helical studies were reconstructed with standard and bone algorithms. Three blinded observers retrospectively evaluated the images. There was no significant difference in motion, image sharpness and anatomic resolution for helical and concentional scans reconstructed with standard algorithm. Furthermore, image sharpness (P |
