What is the difference between PACS and RIS?

PACS handles the images—storing, displaying, and distributing medical images for interpretation. RIS handles the workflow—scheduling exams, tracking orders, managing worklists, and processing billing. They work together: RIS manages what needs to happen, PACS manages the images produced. Modern systems increasingly integrate both into unified platforms, sometimes called radiology workflow solutions.

How is AI changing radiology?

AI assists radiologists by flagging potential findings in images—detecting lung nodules on CT, identifying fractures on X-ray, and prioritizing urgent cases like stroke and pulmonary embolism. AI does not replace radiologists but helps them work more efficiently and catch subtle findings. Current FDA-cleared algorithms serve as clinical decision support tools that augment radiologist expertise rather than replacing it.

Should an imaging center use cloud or on-premise PACS?

Cloud PACS offers lower upfront costs, automatic updates, disaster recovery, and easier multi-site access. On-premise provides maximum control, potentially lower long-term costs for large volumes, and independence from internet connectivity. Small to mid-size imaging centers increasingly choose cloud for cost and convenience. Large health systems may prefer on-premise or hybrid models for control and performance with massive image volumes.

What is Radiology Software?

Radiology software manages the imaging workflow of radiology departments and imaging centers, from order management and patient scheduling through image acquisition, interpretation, reporting, and distribution. Picture Archiving and Communication Systems (PACS) store and display medical images—X-rays, CT scans, MRIs, ultrasounds, and mammograms—for radiologist interpretation. Radiology Information Systems (RIS) handle the administrative workflow including scheduling, tracking, billing, and reporting. Diagnostic viewing workstations provide specialized tools for image manipulation, measurement, comparison, and annotation. AI-assisted diagnosis tools help detect abnormalities like lung nodules, fractures, and breast lesions. Voice recognition and structured reporting accelerate report generation. Integration with hospital EHR systems ensures imaging results are available to ordering physicians promptly.

Key Features to Look For

PACS Image Management

Stores, retrieves, and displays medical images from all modalities in diagnostic quality.

Diagnostic Workstation

Provides specialized viewing tools for image manipulation, measurement, and comparison.

AI-Assisted Detection

Uses machine learning to flag potential abnormalities for radiologist review.

Voice Recognition Reporting

Converts radiologist dictation to structured reports with template-based formatting.

RIS Workflow

Manages scheduling, tracking, worklist management, and billing for imaging operations.

Image Sharing

Distributes images to referring physicians through viewer links and EHR integration.

How Much Does Radiology Cost?

Radiology software involves significant investment. Cloud PACS solutions start at $500–$2,000/month for small imaging centers—Ambra Health, Intelerad, and PostDICOM offer cloud options. On-premise PACS from GE, Philips, or Fujifilm cost $100,000–$500,000+ for implementation. RIS systems run $200–$800/month for cloud or $50,000–$200,000 on-premise. AI tools cost $1–$5/study for algorithms like Aidoc or Viz.ai. Voice recognition (PowerScribe) costs $200–$400/radiologist/month. Enterprise imaging platforms range from $500K–$5M for large health systems.
