Abstract

Subject. Spiral Computer-Tomography (SCT) became an important supplement to the Sellink examination. Multi slice computer tomography (MSCT) achiever a z-axis resolution of 1-2 mm without considerable increase in the acquisition time. In this paper, examination technique in first clinical results ofCT-Sellink examination with MSCT, including the 3D-reconstruction are presented. Materials and methods. The investigations were carried out: with the Somatom Plus 4 Volume Zoom (Siemens, Forchheim) scanner. The following parameters were employed:4 parallel detector ledges collimation 4x1 mm,tube power 140 mA, tube voltage 120 kV, pitch 5 up to 6 mm, slice thickness 1 mm and 2 mm, reconstruction with 50% overlap. Via a duodenal tube, the small intestine was distended by means of 1.5 up to 2.51 methyle-cellulose-suspension. The data were acquired 35 s after injection of 120 mi contrast media (Ultravist). Various methods of postprocessing were applied on a workstation. Results. As of yet, 16 patients were examined with MSCT-Sellink. In 4 cases pathological findings were detected with MSCT-Sellink, which were not recognized with X-ray Sellink. Conclusion. Due to high z-axis resolution and short acquisition time,the morphological details of the small intestine can be visualized utilizing MSCT-Sellink. The data set is well suited for 3D postprocessing. Improvement of diagnostic accuracy can be anticipated.
