Ch 5a Fusion Imaging

Question 1

What is fusion imaging?

Answer 1

An imaging technique that uses 2 different imaging modalities

(ex: u/s with MRI or CT)

Question 2

What is the first thing we setup when doing fusion imaging?

Answer 2

A prior MRI or CT dataset is first uploaded to the u/s machine

Question 3

Do we use fusion imaging often?

Answer 3

No, b/c it takes a long time to do

Question 4

What are the tracking sensors connected to?

Answer 4

The transducer

Question 5

How many tracking sensors are there?

Answer 5

-2 on probe
-1 on pt (the active tracker)

Question 6

The global positioning system (GPS) unit is placed where?

Answer 6

Over the region of interest

(avoid large metallic objects)

Question 7

What should the pt be doing with their breathe during fusion imaging?

Answer 7

Ensure they are in the same state of respiration, by holding their breath, etc.

Question 8

List the 2 main fusion imaging applications?

Answer 8

-Prostate biopsies (m/c)
-Abdominal biopsies

(has a needle tracker so we can see where the tip of the needle is being inserted)

Question 9

Why would we use fusion imaging with prostate biopsies?

Answer 9

Assists with targeting small regions of interest that are hard to see on u/s

(performed at RJH locally)

Question 10

Is fusion imaging done locally with prostate or abdominal biopsies?

Answer 10

Prostate

Question 11

List 3 structures that we would use fusion imaging for when doing abdominal biopsies?

Answer 11

-Liver
-Kidney
-Pancreas

(remember not done locally)
