2. PICOM365

PICOM365 operates on a pay-per-study pricing model targeted at smaller radiology practices seeking usage-based billing. This approach appeals to teams that want to avoid fixed monthly fees while maintaining access to enterprise imaging tools. The platform supports viewing, reporting, and distribution for various specialties including radiology and cardiology.
Per-Study Pricing Model
PICOM365 charges per imaging study rather than monthly subscription, with costs typically ranging from $1 to $5 per study depending on volume and modality. Charges accrue when studies are uploaded to the system. Different modalities like CT, MRI, or X-ray may carry varying fees based on complexity and data size.
There are no fixed monthly minimums required, making this model attractive for practices with fluctuating study volumes. Storage fees may apply beyond the initial retention period if additional space is needed for archived images. This structure allows radiology departments to budget based on actual usage rather than estimated capacity needs.
Storage and Workflow Limitations
Pay-per-study platforms like PICOM365 often include storage limits and workflow constraints that impact growing radiology departments. Common limitations include capped study counts per month, which can restrict expansion during busy periods. Limited concurrent user access may also affect multi-physician practices that need simultaneous system availability.
Basic viewer functionality provides essential diagnostic tools but may lack advanced features found in premium solutions. Restricted modality support can limit the types of studies that integrate seamlessly with the platform. Minimal API access for integrations often requires manual workarounds when connecting with existing EHR systems or third-party radiology software.
