A visit to fluoroscopy room...

Radiology Department

00:06

I'm so excited!

00:08

Me too! This is my first time visiting a radiology department.

00:12

Good morning, Dr Suzy and students. Welcome to the radiology department. I'm Miss fatin, a radiographer here. I'll show you the way to the fluoroscopy room.

00:20

Good morning Miss Fatin. Students, please follow Miss Fatin

00:25

Alright, we are here.

00:27

Thank you Miss Fatin. I will briefly explain about fluoroscopy to the students now.

00:34

So, students, we are now in a fluoroscopic room where a fluoroscopy procedure will be done.

00:41

Dr, what exactly is a fluoroscopy machine?

00:44

Fluoroscopy is a type of machine that transmits a continuous x-ray beam through a patient's body.

00:51

Dr, I have a question. When should we use a fluoroscopy machine? Is it used for all types of examination?

00:57

Fluoroscopy procedures are used in many types of examination, for example, barium x-rays and cardiac catheterization.

01:06

I see. That is pretty amazing!

01:09

Fluoroscopic procedure allows doctors to examine the movement of patient's organs, or identify if there is any blockage in arteries.

01:19

Dr, does the modern fluoroscopy machine have much difference compared to the early ones?

01:24

Of course! Early fluoroscopy machines are only consisted of an x-ray source and a fluorescent screen, where the fluorescent screen will produce visible glow after the x-ray beam passed through the patient.

01:35

Oh cool! Show us, Dr!

01:37

Sure! We have a picture of it right here.

01:39

That looks completely different with what we have now, am I right?

01:43

That is correct. Compared to the early machines, the modern fluoroscopy offers a better image because of it’s latest technological aspects

01:50

What about the radiation dose, Dr? Is there any difference from other machines?

01:54

Good question! Yes, fluoroscopy have different radiation dose compared to other modalities. For example x-ray and CT scan.

02:02

The total radiation exposure depends on the length of the fluoroscopy procedure and the dose of the materials used.

02:08

Fluoroscopy procedure produces higher radiation dose compared to x-ray, since fluoroscope is used over a certain period of time in order to examine the organ functions.

02:16

Dr, I also have read somewhere that an interventional fluoroscopic procedure may expose the patient to the radiation equivalent of 75 - 3000 chest x-rays. Is it true?

02:26

Yes, it is. You can see the comparison of fluoroscopy to x-ray and Ct scan right here.

02:30

Here, you can see that the radiation dose for fluoroscopy is much lower than the CT scan but higher than x-ray.

02:36

However, it is still in the safe level when we compared with the natural background radiation received a year.

02:41

Does it mean that this procedure is more complex to other modalities?

02:44

Yes, fluoroscopy involves more complex procedures.

02:47

Be it interventional or not, that result in longer procedure time and higher doses to patients and medical staff.

02:54

I'm sure that there are effects to the patient and staffs as the radiation doses are higher. Am I correct, Miss?
