Contrast Enhanced Ultrasound Quantification Imaging (CEUS-QI)
CAUTION:
CEUS QI images are provided for reference only, not for confirming a
diagnosis.
The primary goal of CEUS QI is to provide quantitative analysis of CEUS images.
This quantitative analysis includes Trend Curves for quality assessment, Semi Quantitative Color
Parametric Images, Time Intensity Curves (TIC), and Data Tables.
CEUS QI must be configured to a programmable function key before use. These keys
can be configured in Setup / Keys.
1. Press Setup / Keys.
2. Click to select CEUS QI I to the desired key
3. Click Save to complete the setting.
Basic Procedures for Contrast Enhanced Ultrasound Quantification Imaging (CEUS-
QI) in the abdomen
1. Load a CEUS clip from current exam or archive
2. Trim the clip if desired using Trim OLED > scroll left for beginning of trimmed clip > press
Left Set >scroll right to the end of desired trimmed clip > press Right Set
3. Press Programmable key assigned to CEUS QI
4. System produces a trend curve
5. Use the Mark Frame OLED to mark frames for exclusion if desired
6. Use the trackball and Set keys to draw a Global ROI on the B Mode or CEUS image to
include the area of interest
o Global ROI may be a square, an ellipse or a trace
o Pressing UNDO at any given time shall back out of the ROI placement or press the
Delete Current OLED to restart placing the ROI.
7. Press Calc to generate Parametric images of that Global ROI
8. Use the trackball and Set keys to draw Local ROIs on the B Mode, CEUS, or any
Parametric Image frame.
o Up to 10 Local ROIs can be displayed onscreen at any given time.
o Local ROI may be an ellipse or freeform trace
o Pressing UNDO at any given time shall back out of the ROI placement. Alternately,
press the OLED to Delete Current or Delete All.
9. Press Calc to generate TIC/s for each Local ROI.
10. Select the OLED to display the Data Tables corresponding to the ROIs and Parametric
Images.
11. Store the images and data as desired using the Store or Print keys
12. Export the data sets using the Export OLED as desired.
