0:03

Hi everyone.

0:04

In this short video, I'll be showing you a few tips on how

0:08

to view the provided case images.

0:11

After clicking on the case

0:14

and opening it up in a new tab, wait

0:17

for all of the images to load.

0:21

After both the CT

0:22

and PET images are ready,

0:24

the fusion capable popup will appear.

0:28

Drag and drop the CT images onto the main screen,

0:31

and then drag and drop the pet images on top of the ct.

0:35

You will see that the images are now fused.

0:39

A popup will appear at the bottom of the screen.

0:42

It will determine if the window level control at the top is

0:46

for the CT images or the pet images.

0:50

For example, if we keep it on CT

0:53

and exit out of the pop-up window,

0:55

the presets at the top will be for the CT images.

0:59

However, if we click on the gear icon

1:03

and change it to pet, the presets at the top will be

1:07

for the SUV range.

1:10

If you click on the palette icon at the top,

1:13

the color scheme for the pet data can be changed.

1:19

In order to measure the SUV max of a lesion,

1:23

click on the ellipse at the top and simply click

1:26

and drag to form your region of interest.

1:30

In this example, the max SUV of this particular liver lesion

1:34

is 9.92.
