Dti Images - Carestream Vue PACS MR Diffusion User Manual

If you are working with two monitors side by side, you can use a dual-monitor layout. Click Toggle
Dual Monitor in the Layout ribbon. The display is adapted to the dual-monitor environment.
The slider at the bottom of the original series represents values of gradient factor b (sec/mm2). Use
the slider to show the data at the different b-values.
Maps
The following maps are shown:
•
ADC—Displays the apparent diffusion coefficient of water molecules calculated based on the
different gradient images.
•
eADC—Reverses the colors of the ADC map. Because the contrast in the ADC map is the
reverse of regular T2 images, the system generates the eADC map based on the formula
exp(-b*ADC), b being a configurable constant (1000 by default). This map has a similar
contrast to that of regular T2 scans, and reflects the diffusion coefficient ADC.
•
DWI iso—Isotropic map that multiplies the eADC by the T2 image (b=0).
Table
If you add an ROI, a table presenting the calculated values in the ROI is displayed on screen.

6.2 DTI Images

The DTI scan is performed in multiple directions as well as in several gradients (b values). The scan
serves to measure the diffusivity in the various directions and to help draw anatomic conclusion based
1
on these measurements .
The layout presents the calculated maps.
The following illustrations show the initial layout on landscape and portrait monitors.
