CHAPTER 1: INTRODUCTION TO RADIOLOGIC SCIENCE
LE
1. Which of the following best describes the primary purpose of diagnostic radiography?
ST
A. To treat diseases using ionizing radiation
B. To produce images of internal structures for diagnosis
BE
C. To monitor patient vital signs
D. To sterilize medical equipment
Answer: B
Rationale: Diagnostic radiography’s main purpose is to produce images of internal body
structures, allowing physicians to detect and diagnose abnormalities. Options A, C, and D are
unrelated to diagnostic imaging.
2. What is the primary source of ionizing radiation in medical imaging?
A. MRI scanner
B. X-ray tube
C. Ultrasound transducer
D. PET scanner
Answer: B
Rationale: The X-ray tube generates ionizing radiation used in diagnostic radiography. MRI and
ultrasound use non-ionizing energy, while PET uses radioactive tracers rather than producing
radiation in a tube.
3. How does the ALARA principle guide radiologic practice?
A. Maximizing image quality regardless of dose
B. Minimizing radiation exposure while achieving diagnostic quality
C. Limiting patient interaction to reduce infection
D. Increasing exposure time for better penetration
Answer: B
Rationale: ALARA (“As Low As Reasonably Achievable”) ensures patient and staff receive the
minimum radiation dose necessary for diagnostic-quality images.
