<v ->Now we don't do a lot of dual energy CT scanning

0:04

at our institutions in San Diego, but it is used elsewhere.

0:08

And it's reported that the sensitivity and specificity

0:12

of this technique in the diagnosis of gout is 60 to 85%.

0:18

It is useful, dual energy CT,

0:20

to study changes in the size

0:22

of the tophi during treatment.

0:26

There are a number of reasons

0:27

for false negative cases using this technique.

0:30

I've listed a couple there,

0:32

and indeed prominent calcification can also lead

0:36

to false negative dual energy CT scanning.

0:40

And also as and see at the bottom of this text,

0:44

false positive cases are also reported.

0:47

So although dual energy CT scanning is useful,

0:52

there are some diagnostic challenges with which to deal.
