CIIP Regulatory Compliance and Quality Assurance 2 — Questions and Answers
Question 1: Which standard defines the structure and content of radiology reports to enable structured data exchange across imaging informatics systems?
- RadLex Playbook and LOINC codes (Correct answer)
- HL7 v2.x ADT messages only
- SNOMED CT for anatomical pathology
- ICD-10 billing codes
Correct answer: RadLex Playbook and LOINC codes
RadLex Playbook provides standardized procedure naming while LOINC codes enable structured radiology report data exchange across informatics systems.
Question 2: What is the purpose of the ACR's Dose Index Registry (DIR) in imaging informatics compliance?
- Benchmark CT radiation dose indices against national and peer norms (Correct answer)
- Store all radiology images in a national repository
- Certify radiologists for advanced imaging procedures
- Manage billing codes for radiation therapy
Correct answer: Benchmark CT radiation dose indices against national and peer norms
The ACR DIR collects CT dose index data (CTDI, DLP) from participating facilities and provides benchmarking against national norms to support dose optimization.
Question 3: In a PACS implementation, which quality assurance step ensures that images are stored and retrieved without data corruption?
- Bit-exact verification of stored vs. retrieved DICOM files (Correct answer)
- Visual inspection of images by radiologists after archiving
- Checking network packet loss statistics only
- Verifying DICOM AE title configurations
Correct answer: Bit-exact verification of stored vs. retrieved DICOM files
Bit-exact verification (checksum comparison) confirms that stored DICOM files are retrieved without any data corruption or loss.
Question 4: Which federal regulation requires hospitals to report certain adverse events related to medical devices, potentially including failures of imaging informatics systems?
- FDA Medical Device Reporting (MDR) regulation 21 CFR Part 803 (Correct answer)
- OSHA bloodborne pathogen standards
- EPA environmental reporting requirements
- DOT hazardous materials transport rules
Correct answer: FDA Medical Device Reporting (MDR) regulation 21 CFR Part 803
FDA MDR regulation (21 CFR Part 803) requires hospitals to report device malfunctions and adverse events, including failures of FDA-cleared medical device software like PACS.
Question 5: What is the primary purpose of a Service Level Agreement (SLA) between a healthcare organization and a PACS vendor from a compliance perspective?
- Define measurable uptime, response time, and support commitments to ensure regulatory compliance (Correct answer)
- Specify the aesthetic design of the PACS user interface
- Limit the vendor's liability for all data breaches regardless of cause
- Set fixed pricing for all future system upgrades
Correct answer: Define measurable uptime, response time, and support commitments to ensure regulatory compliance
An SLA defines enforceable performance metrics including uptime and support response times, helping organizations meet regulatory availability requirements for clinical systems.
Question 6: Which quality improvement methodology is commonly used in radiology informatics to analyze and reduce repeat imaging studies caused by technical failures?
- Six Sigma DMAIC process (Correct answer)
- Agile sprint planning
- Critical Path Method (CPM)
- Earned Value Management (EVM)
Correct answer: Six Sigma DMAIC process
Six Sigma's DMAIC (Define, Measure, Analyze, Improve, Control) methodology is widely applied to reduce defects and variability, including technical repeat rates in radiology.
