8.5 Contrast Imaging QA
Contrast Imaging QA images are provided for reference only, not for confirming
a diagnosis.
• In case of inaccuracy of the data, do not adjust the depth and the pan-zoom when saving the
cine.
• If the contrast signal inside the selected ROI does not meet the requirements of gamma fitting
condition, that is the bulleting injection, curve fitting may not be available.
Contrast Imaging QA adopts time-intensity analysis to obtain perfusion quantification information
of velocity flow. This is usually performed on both suspected tissue and normal tissue to get
specific information of the suspected tissue.
