Dynamic PET scans with noninvasive blood sampling
A noninvasive method of blood sampling for dynamic PET scans has been invented at McGill University.
Market Need
During a Positron Emission Topography (PET) scan, radioactive tracers are used to visualize certain biological processes in diseases and physical trauma. In some cases, more information is needed and the level of excess tracers in the blood are measured. This procedure requires invasive blood sampling, though, which puts an additional strain on its clinical benefits. With the added time and expertise necessary for blood sampling, many clinics do not utilize dynamic PET scans even though they provide more quantitative information for many of the labeled peptides currently in use.
Technology Summary
This technology is a plastic scintillating fiber detector that is placed directly on the wrist of the patient over the radial and ulnar arties. As this is a non-magnetic and portable sleeve on the arm, the clinician will receive data in real-time while the patient is undergoing a scan. By distinguishing between venous and arterial blood flow, this method will be similar to arterial blood sampling without the need to draw blood.
Advantages
- Noninvasive method of measuring radioactive tracers in blood
- Portable and non-magnetic so the detector can produce real-time data
- Clinician will be able to utilize Dynamic PET scans with greater ease
