Multidetector Computed Tomography (MDCT) Tailored Protocol

• Diagnostic Quality [ Time Frame: Immediately after the single injection of contrast agent ] [ Designated as safety issue: No ]
  Images are to be assessed according to the following scale: 0=Uninterpretable (Image quality severely affected by motion artifacts or technical reasons; need to repeat the examination); 1=Insufficient (Impaired image quality precludes adequate diagnostic assessment because of severe image noise or insufficient contrast enhancement; need to repeat the examination); 2=Adequate (Image quality in terms of noise and contrast enhancement does not interfere with sufficient diagnostic assessment; delineation of small structures may be suboptimal); or 3=Good (Absent or minimal image noise and good contrast enhancement allow adequate diagnostic assessment with clear delineation of even small structures).
  
  

To record technical information and compare image quality regarding routine MDCT procedures with contrast administration using a tailored contrast injection and radiation dose protocol. The hypotheses are that the tailored protocols lead to a lower applied mean radiation dose compared to the use of standard protocols and will provide a more standardized contrast dose per patient size without impairing diagnostic quality.
