Deck 1: Introduction to Imaging and Radiologic Sciences

Question 1

In the diagnosis of patient disease states,physicians can select from an array of medical diagnostic modalities.A few of these involve the use of ionizing energy to create a medical image.If a physician is concerned about the use of ionizing radiation,he or she may choose to order any of the following diagnostic modalities EXCEPT

A)thermograms.
B)medical sonography.
C)radiography.
D)magnetic resonance imaging.

Answer 1

C
Radiography involves the use of x-rays for the production of medical images.Medical procedures such as thermograms,sonograms,and magnetic resonance scans use nonionizing energy forms and consequently do not produce ionizations in human tissue.They are regarded as nonionizing modalities for imaging and offer excellent alternatives to physicians concerned about radiation exposure to patients.

Question 2

Wilhelm C.Roentgen's discovery of "the x-ray" is regarded as one of medicine's most significant achievements.Although his discovery was accidental,his early research was so thorough that no significant findings have been added to his original theories.This in itself is a true tribute to the brilliance of Roentgen as a scientist.One of the most famous early images he created was an x-ray image of his

A)colon.
B)laboratory assistant's foot.
C)wife's hand.
D)kidneys.

Answer 2

C
November 8,1895,is believed by historians to be the day that Roentgen created the famous image of the hand of his wife.Through his investigative methods,Roentgen identified the properties of x-rays.

Question 3

The education of radiographers involves the commitment and dedication of many people.All of the following may be directly involved with and responsible for your education as a radiographer EXCEPT the

A)program director.
B)clinical coordinator or clinical instructor.
C)medical equipment applications specialist.
D)didactic faculty member.

Answer 3

C
Applications personnel from various medical imaging companies are not responsible for the direct teaching of you as a radiographer.They are used to teach users the correct methods for using their various products.Program directors,clinical instructors,and coordinators have direct responsibility for teaching the fundamentals and principles of radiography in preparation for a certification examination.

Question 4

C)germ theory and infection.
D)human genes and genetic engineering.

Question 12

To become a qualified radiologist assistant (RA),you
1)must complete a recognized RA educational course of study.
2)must successfully pass the national examination for nursing (NCLEX).
3)need to be certified in radiography by the ARRT.
4)must successfully complete the radiologist assistant examination offered by the ARRT.
5)need to become a member of a local professional group of radiologic technologists.
