other Clinical significance of prospective ECG-gated dual-source CT in centralvenous angiography Radiation Biology Radiation Biology تحقيق بديع Original Research <div style="text-align: justify;">Background: The study aimed to elucidate the clinical application significance of prospective ECG-gated dual-source CT in central venous (CV) imaging. Materials and Methods: Eighty patients who took CT imaging of CV (CTV) check using dual-source Force CT were enrolled. The control group (helical pitch, 0.8; rotation speed, 0.5 s) and the experimental group (rotation speed, 0.25 s). For both groups, image quality and radiation dose were computed. Results: Cases in the experimental group required longer scanning durations than those in the contro lgroup. In respect to the experimental group, the image quality scores of the superior vena cava and left and right brachiocephalic veins of the patients sharply increased relative to those in the control group. Individuals in the experimental group also presented better image quality scores in left and right subclavian veins, left and right jugular veins, however, this difference was not statistically significant. Lastly, no increase in the radiation dose was bited with the application of prospective ECG gating. Conclusion: The clinical use of prospective ECG-gated technology significantly reduced cardiovascular pulsing artifact interference on the central vein, especially the superior vena cava segment, and remarkably improved the image quality without increasing the radiation dose to patients.</div> Prospective ECG-gated technology, dual-source CTscanner, image quality, radiation dose. 675 678 http://ijrr.com/browse.php?a_code=A-10-1-1097&slc_lang=other&sid=1 X.
