,Chapter 1 – Introduction to Digital Radiography and PACS
Multiple Choice Questions
1. Digital radiography (DR) differs from conventional film-screen
radiography in that:
A. Images are chemically processed
B. Images are stored and manipulated electronically
C. Films must be developed in a darkroom
D. No computers are involved
Rationale: DR uses computers for acquisition, storage, and display of
images.
2. What does PACS stand for?
A. Patient Acquisition Communication System
B. Picture Archiving and Communication System
C. Public Access Computer Storage
D. Processed Analog Communication Standard
Rationale: PACS is the system for storing and distributing digital
medical images.
3. One key advantage of PACS over film-based systems is:
A. Higher radiation doses
B. Faster image retrieval and sharing
C. Requirement for physical storage space
D. Slower communication
Rationale: PACS allows quick electronic access to images.
4. Which imaging modality first introduced PACS?
A. Ultrasound
B. CT
, C. X-ray
D. Mammography
Rationale: CT introduced digital image management earlier than X-
ray.
5. Digital radiography eliminates the need for:
A. Radiation exposure
B. Film cassettes and darkrooms
C. Patient positioning
D. Image receptors
Rationale: Images are digitally acquired and no chemical processing
is required.
6. Which standard allows interoperability between imaging
systems and PACS?
A. JPEG
B. DICOM
C. PDF
D. HL7
Rationale: DICOM (Digital Imaging and Communications in Medicine)
is the standard for image exchange.
7. The main goal of PACS is to:
A. Replace radiologists
B. Store, retrieve, distribute, and present medical images
C. Reduce patient waiting time only
D. Act as an electronic medical record
Rationale: PACS manages imaging workflow.
8. Which component of PACS stores image data long-term?
A. Archive servers
B. Display monitors
