Digital pathology for CROs: The right IMS is a competitive advantage

May 12, 2026

A practical guide for contract research organizations evaluating image management infrastructure for preclinical pathology services

‍

Contract research organizations (CROs) occupy a uniquely demanding position in the digital pathology landscape. Where a single-discipline lab can optimize its image management infrastructure around one workflow type, one regulatory environment, and one client relationship, a CRO has to do all of it simultaneously — across toxicologic pathology studies, discovery research, mIF and spatial biology datasets, GLP and non-GLP work, and a rotating cast of biopharma sponsors with their own expectations for data access, security, and compliance documentation.

That breadth means that CROs are some of the most sophisticated digital pathology users in the industry. It's also what makes the IMS decision more consequential for a CRO than for almost any other organization type. The platform that works for a single-modality, single-client, single-regulatory-framework lab will not work for a CRO. The platform that works for a CRO needs to be enterprise-grade across every dimension — integration breadth, compliance infrastructure, collaboration capabilities, storage economics, and the flexibility to adapt as client needs evolve.

This article is for CRO leaders, lab directors, and informatics teams who are either evaluating their first enterprise IMS or questioning whether the platform they're on is equipped for the demands of modern preclinical pathology services.

The CRO challenge: breadth without compromise

Most digital pathology software is designed with a primary use case in mind. Scanner-bundled IMS software is designed for the scanner vendor's format. GLP-compliance-focused platforms are optimized for regulated tox workflows. Spatial biology tools are built around high-plex imaging. Each makes tradeoffs that reflect a narrower set of requirements than a CRO actually has.

The consequence, for CROs that have tried to stitch together multiple specialized tools, is predictable: format compatibility gaps, inconsistent compliance posture across study types, parallel infrastructure for different workflow categories, and the IT overhead of maintaining integrations between systems that weren't designed to work together.

The more durable solution is a single platform capable of handling the full spectrum of preclinical research without meaningful compromise on any dimension. That's a high bar — and it's the right bar for a CRO to set.

What CRO workflows actually require from an IMS

Support for the full scanner and modality landscape

A CRO's scanner environment reflects its client base and service portfolio — which means it typically includes hardware from multiple vendors, covering brightfield (H&E, IHC, ISH, FISH) and fluorescence (mIF, multiplexed spatial biology) modalities. New scanner platforms get added as new service lines are developed or as clients bring specific equipment requirements.

An IMS that doesn't support the full range of formats in that environment creates friction at the point of image ingestion — the very first step in every study. Format conversion workarounds add time and introduce quality risk. Proprietary format dependencies constrain scanner selection and lock the CRO into specific vendor relationships.

Scanner and format agnosticism — the ability to ingest images from any scanner, in any format, without conversion — is a foundational requirement for a CRO's IMS. It's the capability that protects the organization's flexibility to serve clients who use different imaging platforms and to adopt new scanning technology as the market evolves.

GLP and non-GLP studies on a single platform

Many CROs run both regulated (GLP, GCP) and non-regulated studies. Managing these on separate platforms — one with full compliance infrastructure, one without — creates operational complexity, staff training overhead, and data governance challenges when studies cross regulatory environments.

The better model is a single platform where compliance controls are configurable at the study level: GLP audit trails, reason-for-change tracking, access controls, and validation documentation applied to regulated studies, with a simplified workflow available for discovery and non-regulated research. This approach reduces IT and administrative overhead while maintaining a consistent compliance posture across the portfolio.

For CRO clients that require documented evidence of GLP or GCP compliance — which is most biopharma sponsors for nonclinical safety studies — the ability to provide that documentation from a single, validated platform is a meaningful credibility signal. It's the difference between saying "we have compliance controls" and being able to show an auditor exactly what those controls are and how they performed across a specific study.

Toxicologic pathology workflows: peer review today, primary reads when you're ready

Toxicologic pathology is a core service for most preclinical CROs, and the IMS experience during pathology review directly affects study throughput and pathologist satisfaction. The key capabilities — high-performance image streaming, efficient study navigation, keyboard-driven slide progression, and metadata visible in context — determine whether pathologists experience digital workflows as an improvement over glass-based review or an impediment to it.

For CROs currently establishing or expanding digital tox path workflows, peer review is the natural entry point: enabling distributed, multi-site review without the logistical complexity of shipping glass slides, while building the organizational confidence and validated infrastructure to scale toward fully digital primary reads when the team is ready. PathcoreFlow is built to support both — effortlessly enabling digital peer reviews today, and scaling to accommodate primary reads as your program matures — so the infrastructure investment you make now continues to pay forward.

Multiplex IF and spatial biology: serving a growing client demand

Spatial biology is one of the fastest-growing service areas in preclinical CRO work. Biopharma sponsors are increasingly requesting mIF and high-plex imaging as part of nonclinical study packages, and CROs that can deliver these services on a platform built for the data are in a significantly stronger position than those trying to manage high-plex datasets on general-purpose infrastructure.

The requirements are distinct from conventional brightfield workflows: file sizes routinely reach 50–100GB per image, visualization requires channel-level controls and histogram manipulation that general viewers don't support, and format fragmentation across multiplex platform vendors means that scanner compatibility needs to be validated for each platform in use.

A CRO that can offer clients browser-based access to their mIF datasets — with render settings saved and shared for consistent interpretation across sites — is delivering a service experience that reflects genuine infrastructure investment, not a workaround.

Sponsor collaboration: the capability clients increasingly expect

For a CRO, the relationship with a biopharma sponsor doesn't end when the study is complete. Sponsors want visibility into study progress. Scientific advisors want to review key tissue findings. Project managers want access to images during the study for monitoring and milestone sign-off. And all of these stakeholders want that access to be frictionless — no software installation, no VPN, no file downloads measured in gigabytes.

The IMS is the platform through which all of this collaboration happens. Its collaboration capabilities — or lack of them — directly shape the service experience a CRO can offer.

A platform with secure, browser-based external access, granular permission controls, and the ability to grant and revoke access at the study level transforms sponsor collaboration from a logistics challenge into a differentiating service capability. Sponsors who can access images from anywhere, at any time, with a clean interface and reliable performance, have a fundamentally different experience of working with a CRO than those who receive periodic file transfers and status update emails.

This is increasingly the expectation, not the exception. CROs that can meet it have a tangible competitive advantage in client acquisition and retention.

Storage economics at CRO scale

CROs accumulate image data at a rate that reflects their study volume — which for high-output organizations can mean petabytes of whole slide images across a study portfolio spanning years. The long-term economics of storing that data are a significant operational consideration, particularly for studies conducted under GLP, where regulatory retention requirements may extend for decades.

General-purpose cloud storage pricing at petabyte scale represents a substantial ongoing cost. Hierarchical storage management (HSM) — the automatic movement of data between high-performance and lower-cost archival tiers based on access patterns — is the mechanism that makes that cost manageable without sacrificing data accessibility. Active studies and recently completed datasets remain on fast storage; older data migrates automatically to archival tiers and is retrievable on demand when needed for regulatory submission or sponsor audit.

For CROs, predictable, volume-based storage pricing is also a practical requirement for study costing and client proposals. Storage costs that are transparent, stable, and directly correlated with data volume are far easier to build into service pricing than variable or opaque cloud storage fees.

Integration: connecting the CRO's digital pathology ecosystem

A CRO's digital pathology stack typically includes multiple components that need to work together: whole slide scanners from several vendors, a LIMS or LIS for study and sample management, image analysis platforms for quantitative endpoints, and increasingly, AI-powered tools for specific detection or classification tasks.

The IMS is the hub through which these components connect. Its integration architecture — the openness of its APIs, the breadth of its validated connectors, and the reliability of its data exchange — determines how much of this connectivity is automatic and how much requires manual process management.

For CROs in particular, the LIMS integration question deserves careful evaluation. Study metadata — animal IDs, tissue types, dose groups, staining protocols — needs to be associated with the correct images at ingestion, not entered manually by staff managing a growing study queue. Bidirectional LIMS integration, where metadata flows in and findings flow out automatically, is the standard that eliminates the manual overhead and data integrity risk of parallel data entry.

On the analysis side, open APIs and support for both commercial platforms and custom integrations protect a CRO's ability to offer clients the analysis tools they prefer — rather than being constrained to whatever the IMS vendor has chosen to support natively.

Turnkey infrastructure: what it means for CRO IT teams

CRO IT teams are not typically resourced to build and maintain specialized digital pathology infrastructure. They're managing broader enterprise IT requirements — networking, security, endpoint management, enterprise software — alongside whatever specialized systems the lab has acquired. The expectation that IT will also deploy, validate, and maintain a custom digital pathology platform is rarely realistic.

A turnkey, fully managed IMS deployment changes that dynamic. Cloud-native, SaaS-delivered infrastructure means there's no hardware to procure, no platform to install, and no ongoing maintenance burden for internal IT. Pathcore manages infrastructure reliability, security patching, backup, and disaster recovery. The CRO's IT team gains the benefits of enterprise-grade digital pathology infrastructure without the cost or complexity of building or maintaining it.

For organizations at earlier stages of digital pathology adoption, this model also significantly reduces implementation risk. Rather than a multi-year internal build project with uncertain outcomes, a managed deployment gets teams operational quickly — with a validated, production-tested platform — and scales with the organization as study volume grows.

Evaluating an IMS as a CRO: questions that matter most

The general IMS evaluation criteria apply here, but several deserve particular emphasis for CROs:

Multi-modality and multi-scanner support. Test format compatibility against every scanner platform currently in use — and against the platforms you anticipate adding. This validation needs to be specific, not general.

Support for multiple workflows. CROs have clients and studies across the preclinical research landscape. Make sure your IMS excels at the full spectrum of preclinical digital pathology: peer review, primary reads, spatial biology, device pathology, reporting, etc.

Compliance configurability. Can GLP controls be applied at the study level, with non-regulated studies running on the same platform without those controls? Validate that the compliance architecture actually supports mixed-regulatory environments rather than requiring separate infrastructure.

Third party integrations. With clients using every scanner, analysis, and LIS/LIMS platform in the digital pathology environment, it's vital that your IMS has an open API and multiple native integrations to sync data bidirectionally.

External access quality. Evaluate the sponsor collaboration experience from the outside in — specifically, what a biopharma client actually sees and experiences when they access study images. Performance, interface clarity, and the absence of installation requirements all matter to the client relationship.

Validation support. For GLP work, ask specifically about the validation documentation package — IQ, OQ, and the process for producing study-specific validation records. A vendor with a clear, well-documented CSV support process is a materially different partner than one that treats validation as the customer's problem.

Storage pricing transparency. Get a written, per-terabyte pricing model that covers active storage, archival tiers, and retrieval costs — and model it against projected study volume growth. The total cost of storage over a five-year horizon should be a factor in the platform decision, not a surprise after deployment.

The platform that grows with your practice

The CROs best positioned in the digital pathology market are not necessarily those that made the technology transition earliest. They're the ones that made it on the right infrastructure — platforms capable of handling the full range of preclinical services, supporting compliance requirements across study types, and delivering the sponsor collaboration experience that biopharma clients increasingly expect as standard.

The IMS is where that positioning starts. It's the infrastructure decision that determines which services you can offer, how efficiently you can deliver them, and how your clients experience working with you. Getting it right is one of the highest-leverage investments a CRO can make in its digital pathology program.
