Time-intensity curves (TIC)

 

The time-intensity curve tool allows you to visualize the lesions' enhancement behavior (e.g. in Breast MRI) by plotting the signal intensity values over time after the administration of contrast material.

 

Plotting time-intensity curve

 

1) Open a study with dynamic sequences.

2) Press  F4  to show the "Open multiple series" window, select the dynamic series (including the unenhanced one). A series with subtraction enabled will also come handy to quickly localize lesions.

3) Find a lesion that you would like to analyze and draw an ellipse over it.

4) Quickly duplicate the ellipse ROI into other series by using the  Ctrl + Shift + D  shortcut.

5) Select  Time-intensity curve  from  Advanced tools  or use  Ctrl + Shift + E  .

6) RadiAnt DICOM Viewer selects the series for curve generation automatically.

Make changes to the selection if you want to use other series. Click  OK  to confirm the selection and generate curve.

7) A new panel will be added. It contains the time-intensity curve and screen captures of the region in dynamic series used for calculations.
