NOTE: In MFE status, patient should lie down and hold breath, and transducer should be kept still.
5.13.5 Contrast Imaging QA
CAUTION:
Contrast Imaging QA images are provided for reference only, not for
confirming a diagnosis.
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.
1. Perform image scanning, freeze the image and select a range of images for analysis; or select a
desired cine loop from the stored images.
NOTE: in case of inaccuracy of the data, do not adjust the depth and the pan-zoom when saving
the cine. Also, during image scanning, ask the patient to hold breath for several seconds, and keep
the probe still until the image is frozen.
2. Tap [Contrast QA] on the touch screen page to activate the function.
3. Mark out the interested part (ROI).
If necessary, perform curve fitting on the time-intensity curve.
4. Analyze the parameters of the curve, or perform B measurement.
5. Save the curved image, export the data and do parameter analysis.
