━━━━━━━━CHAPTER 1 — INTRODUCTION TO RADIOLOGIC SCIENCES ━━
1. Who is credited with the discovery of X-rays?
A) Marie Curie
B) Thomas Edison
C) Wilhelm Conrad Roentgen
D) Henri Becquerel
E) Nikola Tesla
✔ Correct Answer: C) Wilhelm Conrad Roentgen
EXPERT RATIONALE: Wilhelm Conrad Roentgen discovered X-rays on November 8,
1895, while experimenting with cathode ray tubes. He named them "X-rays"
because their nature was unknown at the time.
2. The primary goal of radiologic technology is to:
,A) Administer medications to patients
B) Perform surgical procedures under imaging guidance
C) Produce diagnostic images while minimizing radiation exposure
D) Interpret radiographic images for clinical diagnosis
E) Develop treatment plans for cancer patients
✔ Correct Answer: C) Produce diagnostic images while minimizing radiation
exposure
EXPERT RATIONALE: The radiologic technologist's core role is to produce high-
quality diagnostic images using the least amount of radiation necessary to protect
both the patient and the technologist.
3. Which of the following best describes the scope of practice for a radiologic
technologist?
A) Diagnosing disease from radiographic images
B) Prescribing contrast media for imaging procedures
C) Performing radiographic examinations and related patient care
D) Independently ordering imaging studies for patients
E) Performing biopsies under fluoroscopic guidance without supervision
✔ Correct Answer: C) Performing radiographic examinations and related
patient care
EXPERT RATIONALE: Radiologic technologists are trained to perform imaging
procedures and provide associated patient care, but diagnosis and prescription
remain outside their scope of practice.
4. Which imaging modality uses sound waves to create diagnostic images?
A) Computed Tomography (CT)
,B) Magnetic Resonance Imaging (MRI)
C) Ultrasonography
D) Nuclear Medicine
E) Fluoroscopy
✔ Correct Answer: C) Ultrasonography
EXPERT RATIONALE: Ultrasonography uses high-frequency sound waves reflected
from body tissues to create real-time images, making it unique among imaging
modalities in that it uses no ionizing radiation.
5. The branch of medicine concerned with the use of radioactive substances in
diagnosis and treatment is called:
A) Radiology
B) Radiography
C) Nuclear Medicine
D) Radiation Oncology
E) Fluoroscopy
✔ Correct Answer: C) Nuclear Medicine
EXPERT RATIONALE: Nuclear medicine uses radioactive tracers
(radiopharmaceuticals) introduced into the body to evaluate organ function and
detect disease, distinguishing it from structural imaging modalities.
6. Which of the following best describes fluoroscopy?
A) A static X-ray image of the chest
B) Real-time dynamic X-ray imaging
C) Imaging using magnetic fields and radio waves
, D) Imaging using gamma ray emissions
E) Ultrasound-guided imaging of soft tissue
✔ Correct Answer: B) Real-time dynamic X-ray imaging
EXPERT RATIONALE: Fluoroscopy produces continuous X-ray images displayed on
a monitor in real time, allowing visualization of moving structures such as the
gastrointestinal tract and cardiac function.
7. The field of imaging that uses powerful magnetic fields and radiofrequency
waves to produce images is:
A) CT scanning
B) Nuclear medicine
C) Mammography
D) Magnetic Resonance Imaging (MRI)
E) Interventional radiology
✔ Correct Answer: D) Magnetic Resonance Imaging (MRI)
EXPERT RATIONALE: MRI relies on the behavior of hydrogen protons in a strong
magnetic field when stimulated by radiofrequency pulses, producing detailed
images of soft tissue without ionizing radiation.
8. Which of the following is considered a non-ionizing form of radiation used
in medical imaging?
A) X-rays
B) Gamma rays
C) Radiofrequency waves used in MRI
D) Beta particles
E) Alpha particles
