The Background

A Cardiologist Who Built the Infrastructure First Then Saw What Was Still Missing

Dr. Martin Kloosterman is a specialist in cardiac electrophysiology with deep clinical expertise in cardiac implantable electronic devices (CIEDs) - pacemakers, ICDs, loop recorders, and leadless devices. Over his career, he personally witnessed the coordination failures that occur when a CIED patient is scheduled for an MRI without device compatibility having been verified in advance.

To solve this at the coordination level, Dr. Kloosterman built Smart-Praxis - a multi-role healthcare SaaS platform at mrisafemode.com - now serving 243 registered users across hospitals, MRI centers, device manufacturers, and clinical experts. The platform digitizes the full MRI Konditionierung (MK) workflow: pre-scan device programming, multi-party coordination, and post-scan reprogramming.

But one critical gap remained. While Smart-Praxis handled institutional coordination, clinicians at the bedside still had no fast, reliable tool to answer the foundational question before scheduling began: Is this specific cardiac device system actually MRI-conditional? That gap became MRI Logic.

Adrian Chung, Founder of Carevation

Cardiac Electrophysiology Expert

CIEDs, pacemakers, ICDs, and leadless devices

"The manual process for checking MRI conditionality was slow, fragmented, and completely dependent on the individual clinician's knowledge. I needed a tool that gave any clinician the right answer in seconds - regardless of their familiarity with specific device models."

Core Problem

The Old Reality

What clinicians were actually using before MRI Logic:

The real consequences of this fragmentation:

Last-minute scan cancellations after patient prep - wasted clinical time every single day

Incomplete audit trails - no formal documentation of compatibility decisions

Knowledge-dependent accuracy - no standardized logic across different clinicians

Cross-manufacturer combinations handled inconsistently with no defined protocol

Delayed diagnosis for patients genuinely needing MRI imaging

MRI Safety Checks Were Slow, Manual, and Clinically Fragmented

Before MRI Logic, there was no single tool to verify cardiac device MRI compatibility at the point of care. The consequences were not minor inconveniences they were clinical risks and significant operational waste happening daily across every MRI center in the country.

Manufacturer Websites

Four separate portals, different formats, no cross-reference capability

MRI Compatibility Check: Before vs. After MRI Logic

Before

Manual website lookups across four manufacturer portals. 20-45 minutes per patient. No structured documentation. Scans cancelled after patient prep. Accuracy entirely dependent on individual knowledge. Cross-manufacturer cases handled with no defined process.

After

Single OCR scan or manual entry in the app. Color-coded result in under 10 seconds. Instant PDF report generated automatically. Compatibility confirmed before scheduling begins. Standardized logic ensures consistent decisions regardless of who performs the check.

What Triggered This Project

The Moment It Became Undeniable

Three clinical realities converged to make MRI Logic both urgent and necessary:

Scans Were Being Cancelled at the Last Minute

MRI centers routinely discovered too late that a patient's cardiac device was not MRI-conditional - after the patient had already been scheduled, prepped, and brought to the suite. A 10-second check before scheduling would prevent hours of wasted clinical time and unnecessary patient distress.

Manual Multi-Source Lookups Were Creating Accuracy Risks

Staff relied on manual checks across four separate manufacturer portals - each with different formats and update cadences. Accuracy depended entirely on individual knowledge, not a standardized system. For a life-critical clinical decision, that was not acceptable.

Smart Praxis Had the Infrastructure But Not the Point of Care Tool

The Smart-Praxis web platform could coordinate the MRI workflow between institutions - but it couldn't answer the pre-scheduling compatibility question that triggered the whole process. MRI Logic was designed as the mobile front door: the instant check that feeds into the broader Smart-Praxis ecosystem.

Business Process Reengineering

We Didn't Digitize the Old Process. We Replaced It.

MRI Compatibility Check: From 45 Minutes to 10 Seconds

Manual lookup across four separate manufacturer websites. 20-45 minutes per patient. Accuracy entirely dependent on the individual clinician's knowledge of specific device model generations and manufacturer update cycles.

OCR scan or manual entry in the app. Standardized logic engine delivers a color-coded result in under 10 seconds. Consistent, accurate, and independent of who is performing the check.

Documentation: From No Audit Trail to Instant PDF

No structured documentation of the compatibility decision. Manual notes, if made at all. Audit trails incomplete. Patient records without any formal evidence of the check having been performed.

Every check generates a formal PDF report - patient details, device models, result, restrictions, and timestamp. Shareable in seconds. Added directly to the patient file with one tap.

Finding MRI Centers: From Google Searches to In App Discovery

Patients and referring clinicians searched Google, called hospital switchboards, or relied on word of mouth to find nearby MRI centers. No way to filter by machine type or verify center details quickly.

Full US MRI center database searchable directly in the app. Filter by location, machine type, and distance. Complete center profiles with directions, hours, website, and contact info - all in one place.

Scan Cancellations: From Last Minute Discovery to Pre Scheduling Prevention

Incompatibility discovered after the patient was already scheduled, prepped, and in the MRI unit. Wasted clinical time, distressed patients, and disrupted scan schedules.

Compatibility checked before scheduling begins. Only MRI-conditional patients enter the queue. Scan cancellations due to device incompatibility are eliminated at the source.

Results

Early Access Validated Real Clinicians. Real Impact.

MRI Logic is currently in active deployment with its initial clinical user base providing structured feedback. Qualitative outcomes from early use have validated the platform's design against the most critical pain points in cardiac MRI safety workflows.

What Early Access Users Are Reporting

Clinicians report feeling significantly more confident about MRI conditionality decisions - the guesswork has been removed entirely

MRI center staff describe the compatibility check as faster and more reliable than any manual method they had previously used

The OCR scanning feature is consistently rated the highest-value interaction - eliminating the most error-prone step in the workflow

Having a formal PDF report generated automatically is described as the single biggest improvement to the documentation process

The color-coded result system is immediately intuitive - no training required to interpret and act on the result with confidence

Social Impact Potential at Scale

FOR MRI CENTERS

Fewer cancelled scans, faster patient throughput, and a standardized safety process that no longer depends on individual staff knowledge or availability

01

FOR CARDIAC PATIENTS

Faster access to MRI imaging they previously waited weeks for - simply because device compatibility could not be confirmed quickly enough

02

FOR HEALTHCARE SYSTEMS

Reduced clinical waste, stronger audit trails, and a consistent safety protocol that scales across every unit, every clinician, and every shift

Key Learnings

What Building MRI Logic Taught the ForNex Health Team

Targeting
Product Insights

Medical logic engines require domain first thinking, not technology first.

"The conditionality rules engine is the entire value of this product. Investing heavily in understanding the clinical logic - manufacturer rules, cross-device combinations, SAR limits, exclusion zones - before writing a single line of code was the prerequisite for everything else being trustworthy."

Ideal For Organizations Like Yours

If Any of These Sound Like You,
ForNex Health Is the Right Partner

You're a physician founder with deep domain expertise and a defined product vision.

The most impactful clinical tools are built by people who have experienced the problem firsthand. If you have the clinical knowledge, ForNex provides the full technical execution - from architecture to app store - with a team that understands healthcare at a clinical level, not just a technical one.

You're building a clinical decision support tool that requires a complex logic engine, not just a UI.

MRI Logic's conditionality rules engine - encoding four manufacturers' datasets into a precise, clinically validated decision system - is exactly the kind of rule-based medical architecture ForNex specializes in. Clinical logic applications demand a fundamentally different level of accuracy than standard consumer apps.

You need a mobile first product on both platforms with an enterprise grade backend.

MRI Logic was built in React Native for cross-platform mobile with a .NET + MS SQL Server backend on Windows Server - selected specifically for clinical-grade reliability, structured data integrity, and compatibility with existing healthcare IT environments.

You're building an MVP with a roadmap that expands significantly in subsequent phases.

We architected MRI Logic's database schema and API contracts to be category - agnostic from day one. Adding the MRI Centers module in Phase 2 required no rebuild. Phase 3's AI chatbot and booking system build on the same foundation - not alongside it.

You're integrating AI into a clinical workflow where speed and accuracy both matter.

MRI Logic uses Groq AI as its intelligence layer - and Phase 3 will introduce an AI chatbot assistant for clinical queries. ForNex Health integrates AI into medical workflows with accuracy as the non-negotiable constraint, not an afterthought.
