Technology
From a routine scan to actionable intel.
PROMEDX quantifies the standard nuclear liver–spleen scan, converting routine imaging into validated, reproducible measures of organ function.
Scan
Patients receive a standard quantitative liver–spleen scan at a local imaging center. Non-invasive, widely available, reimbursable.
Quantify
PROMEDX FDA approved software analyzes the study and computes the six functional indices with validated algorithms.
Stage
Your physician receives a clear report: index values, trends over time, and a physiologic stage H0–H5.
Perfused hepatic mass
Functional reserve, imaged directly.
PHM measures the mass of working, perfused liver tissue. Patients with normal-range PHM can carry advanced fibrosis yet remain compensated: exactly why function, not scarring, drives prognosis.
- Reproducible and operator-independent
- Sensitive to change — ideal for longitudinal monitoring
- Performance maintained in obesity and ascites, where elastography struggles
The signature model
Physiologic staging, H0–H5.
A staging system built on measured physiology — from normal function to decompensated disease.
Stages reflect quantitative functional thresholds associated with clinical outcomes in the published evidence base.
Why quantitative
Where common tools fall short.
Blood-panel scores
Indirect and insensitive in key populations. Published comparative data show limited ability to identify patients at real risk.
Elastography
Measures stiffness, not function; published series report unreliable cirrhosis detection in important settings.
Biopsy
Invasive, sample-limited and impractical for monitoring — the reference standard nobody wants to repeat.
