So let's talk about the Imaging modality that

0:03

we use to guide us in interabdominal lesion

0:06

biopsies.

0:08

One of the workhorses as it relates to

0:11

Imaging guidance is the CAT scan. What are the advantages? We

0:14

know that it offers High degree of spatial resolution, which

0:17

for us provides us kind of full visualization of

0:21

the needle path along and trajectory. It's particularly

0:24

ideal for digitalizing deep lesions and

0:27

the momentum and the messenger and the ratchet peritoneal as well. The

0:30

visualization is particularly possible really in

0:33

most patients regardless of their position including if they're

0:36

prone that is awesome for us

0:39

regardless of the patient's habitus, which makes this

0:42

a particularly helpful modality.

0:45

What are some disadvantages well, sometimes we don't

0:48

really have that real-time maneuverability. Although CT fluoroscopy does

0:51

support that to some degree. There are

0:54

some costs involved in CT which makes it sort of

0:57

less accessible in certain parts of the world and there's

1:00

radiation exposure which is important for us to mention particularly when

1:03

we have patients that require interdominal biopsies

1:06

that may be in the Pediatric population.

1:09

When it comes to Ultrasound very helpful as it

1:12

has good real time maneuverability and supports patients

1:15

that may be moving. It supports

1:18

our ability to manipulate the probe

1:21

in a way in order to find the best trajectory

1:24

for our tissue sampling.

1:27

Slow cost which in many ways makes this something that's

1:30

particularly accessible across the globe and there's

1:33

no radiation exposure with conversely to CT makes

1:36

this one of those modalities that actually can be

1:39

particularly good for patients in the Pediatric population. And

1:42

since many of our pediatric patients

1:45

are

1:47

of smaller body habitases than their adult counterparts it

1:50

actually something that lends itself to good penetration

1:53

as well when it comes to disadvantages. Well, if you're

1:56

dealing with an adult population, there could

1:59

be some depth issues when it comes to Ultrasound which as I

2:02

mentioned before in the case of pediatric patients, it's not

2:05

really something that we encounter to any challenging

2:08

degree when it comes to superficial peritoneal

2:11

lesions is actually can be very good allows us

2:14

to see through the skin into the anterior abdominal wall.

2:17

So you abdominal wall, for example what when

2:20

it comes to patients who need to be

2:23

positioned prone, it may not actually

2:26

be so great in allowing us to penetrate to

2:29

the depths needed.
