      TUBE POTENTIALS FOR IODINATED CONTRAST STUDIES.

AB  - This paper aimed to investigate effects of different tube voltage and image 
      quality settings on radiation dose and image quality for patients undergoing 
      computed tomography iodinated contrast studies using automatic tube current 
      modulation system and to recommend settings to achieve improved radiation dose 
      and image quality values. A Pagoda phantom with an additional rod of iodine 
      contrast was scanned using different tube voltages and noise index (NI) settings. 
      Size-specific dose estimate (SSDE) and image quality (noise, contrast, 
      contrast-to-noise ratio (CNR) and figure of merit (FOM)) were analysed. Values of 
      SSDE were maintained with similar NI settings. Contrast and CNR were higher for 
      lower tube voltage settings. Better FOM values can be achieved with higher NI 
      settings with the lower kVs. To achieve better CNR and SSDE compared with the 
      standard setting of 120 kV, a 80 kV with an NI setting of 15 was recommended.
