Intro to veterinary radiology

Question 1

Who discovered/invented xrays?

Answer 1

Wilhelm Conrad Röntgen in 1895

Question 2

What year did Wilhelm Röntgen discover/invent xrays?

Answer 2

1895

Question 3

First xrays was of..?

Answer 3

It was of Mr. Röntgen’s wife’s left hand on Dec 22nd, 1895.

The image was a “positive radiograph” causing the colors to be inverted.
(As opposed to the typical negative.)

Question 4

What is fluoroscopy?

Answer 4

informally referred to as “fluoro”, is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object.

“xray video”

radiation doses can be high

Question 5

Who discovered evidence of radioactivity and when?

Answer 5

Henri Becquerel in 1896

Question 6

Radioactivity is also known as

Answer 6

radio decay, the spontaneous decomposition of an unstable atomic nucleus which results in emission of particles and/or electromagnetic radiation (gamma photons).

Question 7

Bq is

Answer 7

radioactivity unit

Question 8

radioactivity unit is denoted..?

Answer 8

Bq or becquerel

Question 9

Marie Curie was…?

Answer 9

a french physicist and chemist

Question 10

What did Marie Curie discover and when?

Answer 10

radium and polonium radioactive elements in 1898.

1903 received the Nobel Prize in Physics.
1911 received the Nobel Prize in Chemistry

Question 11

Angiography is

Answer 11

the X-ray imaging of blood vessels using contrast agents injected into the bloodstream through a thin plastic tube (catheter) that is placed directly in the blood vessel.

The angiograms taken can clarify the condition of the blood vessels and
the blood supply of the organs, and allows the treatment of certain
blood diseases.

Question 12

CT is

Answer 12

Computertomography, diagnostic imaging

CT can expose people to relatively large amounts of ionizing radiation

Question 13

Different planes in CT

Answer 13

axial
coronal
sagittal

Question 14

which plane is this

Answer 14

axial

Question 15

which plane is this

Answer 15

coronal

Question 16

which plane is this

Answer 16

sagittal

Question 17

what CT plane

Answer 17

axial plane

The axial plane can be thought of as slices through the patient. The axial plane is the one that radiologists use the most, but it is not the most intuitive, and the anatomic right and left are reversed on the image.

Question 18

what CT plane

Answer 18

coronal plane

Question 19

what CT plane

Answer 19

sagittal plane

Question 20

define mammography

Answer 20

the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast for diagnosis and screening.

Question 21

define DXA

Answer 21

DXA is an abbreviation for dual-energy X-ray absorptiometry.

also known as bone densitometry

Bone mineral density (BMD) is measured. Usually bone density is measured in the spine L1-L4 and / or femoral neck.

Question 22

Bone densitometry DXA (Dual-Energy X-ray Absortiometry) is used to

Answer 22

diagnose osteoporosis or bone loss, to assess the need for treatment and its effectiveness.

Usually bone density is measured in the spine L1-L4 and / or femoral neck.
