Question 8

AP lordotic lung

Answer 8

Some cloudiness spread out in lungs

Question 9

Pneumonia lung

Answer 9

Lots of spots(buildup of phlegm - inflamed) in lungs (alveoli are inflamed)

Question 10

Tension Pneumothorax

Answer 10

Lungs are giving up

Question 11

Atelectasis

Answer 11

collapse of lung

Question 12

What do CT scans do? !!!!

Answer 12

CTs use the same technology as X-rays but produce images in a cross-section.

CT scanner focuses narrow x-ray beam thru patient, x-ray detector & x-ray tube assembly rotates around the patient

this creates CT data sets of human anatomy on a slice-by-slice basis, analogous to “slicing a loaf of bread.”

Diff densities of various structures & organs absorb the x-rays in varying degrees, displayed in 3-D

Question 13

What can CT scan provide vs X-ray scan? !!!!

Answer 13

CT scans can detect conditions not seen in a conventional X-ray, such as:

Structures in the brain including tumors
Blood clots
Enlarged ventricles
Abnormalities in the nerves or muscles
Abdominal masses
Bone fractures

Question 14

When did radiology start?

Answer 14

late 1800s

Question 15

What is Radiology?

Answer 15

a medical specialty that creates & interprets pics of the human body’s organs & body systems to diagnose sickness/injury

Question 16

In many ways, radiology serves every healthcare sector, including..

Answer 16

emergency medicine, pediatrics, trauma response, infectious disease, orthopedics, dentistry, orthodontics, obstetrics, cancer care(oncology)

Question 17

X-ray technologies

Answer 17

radiography, CT scanning, DXA scanning, mammography, angiography, interventional medicine

Question 18

Who discovered tomography?

Answer 18

Dr. Alessandro Vallebona

Question 19

Who discovered Ultrasound tech?

Answer 19

Although Scottish obstetrician Ian Donald created the first ultrasound in 1958, the technology goes back to Jacques and Pierre Curie in 1877

Question 20

Who discovered MRI’s ?

Answer 20

Raymond Vahan Damadia

Question 21

Who discovered CT scans?

Answer 21

Godfrey Hounsfield and Allan Cormack

Question 22

Who discovered the x-ray

Answer 22

Wilhelm Conrad Roentgen

Question 23

Ultrasound tech does what?

Answer 23

ultra-high frequency sound waves for medical procedures.

Question 24

Tomography

Answer 24

use of x-rays to create images.
The creation of x-ray image data sets as slices

Question 25

MRI

Answer 25

atomic characteristics of magnetism and radio-frequencies of cells & tissue images (atomic level) does not use radiation reveals tissues state/ diseases at cellular level

Question 26

digital (DR) and computed (CR) radiography

Answer 26

DR - flat panel detectors and thin film transistor technology that convert X-rays to electrical charges directly or indirectly CR - cassette-based phosphor storage plates (PSP) which are then scanned into a digital format by a computerized system for picture processing, archiving, and display. With both CR and DR, the entire operation is digitized to produce radiographic images

Question 27

PET

Answer 27

imaging uses radionuclides to reveal metabolic or biochemical activity of tissues & organs helps find cancer stages

Question 28

Future of Radiology

Answer 28

AI, magnetic resonance microscopy (MRM) for deep tissue imaging, medical imaging informatics
