| Abstract text: | Objectives: We want to determine the benefits of investigating the same body vessels with a multi-slice computed tomography (CT) versus a single-slice CT. Methods: We are comparing the whole exam information resulted by a single-slice CT scanning with similar investigations made by a multi-slice CT. We calculated the tissue volume scanned, the resolution of images obtained by direct scanning and by post processing (2D and 3D reconstructions) etc. Results: The volume of information obtained with the multi-slice CT is much bigger (several times), more accurate, with less motion artifacts, with a higher resolution, quicker acquisition time, and more supplementary post-processing options than a single-slice CT. The contrast substances injection is used with a bigger efficiency because of the increased speed of scanning, so we can use a smaller quantity. The radiation doze that was given to patients during an examination performed by a multi-slice CT is the same or a little bit increased than the doze of a single-slice CT exam of the same body region. Conclusions: Multi-slice CT is offering us a very much more information of the same segment examined, in a shorter acquisition time. In this case the angiography reconstructions are more accurate and with a higher resolution, so that we can observe more detailed the patient’s vessels. |
