Radioactive water (O-15 H2O) is the gold standard for quantifying blood flow. We’re making it practically available for routine use.

More accurate

Simpler kinetics compared to other known tracers

Better safety

Increased safety for patients and reduced staff risk

Faster turnaround

Three double exams (stress and rest) per hour, eight hours or more per day!


MedTrace (Denmark) has developed several novel safety features, which combined will revolutionize blood flow imaging in PET. Our solution automates bedside production and infusion of radioactive water in the PET scanner suite – just in time for medical demands. The solution consists of a remote operated unit producing the radioactive water and two disposable kits, including a daily kit for production, and a patient kit for infusion.

The MedTrace system is considered a platform technology. Our first priority is the heart study application, subsequently brain and tumor vascularization and diabetes studies. Micro-vascular applications will be considered as well.

“The flow of water through the tissues is essentially what makes life possible. All diseases affect the flow of water one way or another. This opens up powerful opportunities of diagnosis using 15O-water and PET”

Professor Jens Soerensen MD PhD, PET Centre, Uppsala University Hospital, Sweden



Today’s myocardie perfusion exams use TC99m, Rb-82 and NH3 to treat patients. The globally recognized gold standard tracer for blood flow analysis is O-15 H2O (radioactive water), which is used in most clinical studies as the benchmark. The short half-life of radioactive water as well as lack of regulatory approved equipment has limited its use in clinical practice so far. MedTrace is a Danish life science startup that has developed a fully automated water system with unique and patent- pending safety features. Connected to an in-house cyclotron, the MedTrace water system will efficiently produce radioactive water and inject it into the patient in the PET scanner.


Access to gold standard tracer (O-15 H2O) for routine blood flow exams
Faster patient turnaround (2-3 double-tests/hour)
Absolute safety for patients and staff
In-house production of the tracer- no 3rd party logistics dependencies
Oncology Tumor microvasculature
Neurology   Functional bloodflow – Apoplexy, Alzheimer’s
Diabetes Diabetec foot
Cardiology Take out “the gold standard”
Clinical physiology Organ blood supply
Tissue perfusion Ischemic muscle, collateral blood supply
Tumor microvasculature.
Blood flow to selected brain domains, incl. quantification of apoplexy, alzheimer, dementia, schizophrenia etc.
Diabetec foot.
Myocardial perfusion – the gold standard.
Clinical Physiology
General organ specific blood perfusion, for organ functionality assessment.
Tissue perfusion
Ischemic muscle, collateral blood supply.



We are a Danish based startup with an international agenda. Having experienced the challenges with false results in myocardial perfusion imaging, we are determined to make radioactive water (O-15 H2O) practically available for clinical use allowing doctors to use the gold standard in the clinic.


MedTrace currently collaborates with Scandinavian university hospitals and global industry partners within nuclear medicine. We are still looking for interested clinical, technological and commercial international partners.

“The availability of a reliable CE approved system for bed-side production of O-15 water could change O-15 water PET from an exotic research tool to a clinical workhorse”
