FIU’s portable preterm imaging device faces clinical testing
FIU doctoral students Jenny Pei and Amanda Sanchez are leading PPRIM’s commercialization effort as PolarDoc.
Key Takeaways
- •FIU says a clinical trial and FDA clearance are future steps.
- •A 2024 prototype paper reported imaging tests on nonpregnant volunteers.
- •The device’s accuracy in predicting preterm birth has not been established by that paper.
Florida International University researchers are developing a portable imaging device intended to help study signs associated with preterm birth. A clinical trial and FDA clearance remain future steps, the university said in a November 10 update. Read FIU’s update.
The device, called PPRIM for Portable Preterm Imaging, uses polarized light to capture images of cervical tissue.
What the earlier study tested
A 2024 Journal of Biomedical Optics paper reported that the portable system could image a healthy, nonpregnant cervix and measure polarization properties of test materials. That study did not establish how accurately the device predicts preterm birth in pregnant patients. Read 2024 research paper.
An earlier imaging approach used a larger colposcope. The portable device was designed to work without a speculum, according to the 2024 research paper.
What comes next
FIU says researchers plan a clinical trial to connect device measurements with patient outcomes. The university also identifies FDA clearance and scaled manufacturing as steps before the device could reach patients.
For South Florida clinicians and health technology teams, those milestones would determine whether an experimental imaging concept can become a practical clinical tool.
