In a groundbreaking achievement, Polish researchers from the Jagiellonian University in Krakow and the Medical University of Warsaw have developed an innovative approach to cancer diagnostics that could transform how tumors, especially brain cancers, are detected and studied. By employing a unique imaging technique involving “positronium lifetime” with the J-PET tomography scanner, this technology aims to enhance diagnostic accuracy and potentially phase out invasive biopsy procedures.
At the heart of this innovation is the J-PET (Jagiellonian Positron Emission Tomography) scanner, an advanced PET imaging device designed by Professor Paweł Moskal’s team at Jagiellonian University. Unlike conventional PET scans, which focus solely on the distribution of radioactive tracers, the J-PET system introduces an additional measurement of the positronium atom’s lifetime. Positronium, an exotic atom composed of an electron and a positron, plays a key role in detecting cancerous tissue. Research has shown that positronium atoms have a shorter lifespan in cancerous tissues than in healthy ones, a phenomenon that J-PET measures with unprecedented precision.
Professor Ewa Stępień, a collaborator on the project, highlighted this feature as a major breakthrough, explaining that standard imaging devices have been unable to measure positronium lifetimes, making J-PET uniquely capable of providing a more nuanced view of cancerous tissue. This capability is particularly promising for gliomas, a type of aggressive brain tumor that has historically been challenging to diagnose and monitor.

The J-PET technology recently underwent clinical testing on glioma patients at the Medical University of Warsaw, under the guidance of Professor Leszek Królicki and Professor Jolanta Kunikowska. Initial results have been encouraging, demonstrating J-PET’s potential to deliver highly detailed three-dimensional images of brain tumors, helping physicians to identify malignant tissue without invasive biopsies. While the device’s current version focuses on brain imaging, Professor Moskal’s team is already working on a full-body version anticipated to be available by 2028. This next-generation J-PET will further expand diagnostic possibilities, including tracking drug metabolism and examining quantum photon entanglement for more sophisticated imaging.
Beyond diagnostic precision, J-PET brings practical advantages in cost, weight, and accessibility over traditional PET scanners, making it more feasible for widespread clinical use. Testing conducted at the University Hospital in Krakow confirmed that J-PET is not only effective but also significantly less expensive and lighter than conventional PET machines, positioning it as a versatile option for medical facilities.
Cancer remains a significant health issue in Poland, where 100,000 people die from cancer annually, and over 1.17 million individuals are affected by the disease. The potential for J-PET to replace invasive biopsies with virtual ones, coupled with its affordability, holds promise for improving cancer diagnostics and care accessibility. While the technology will require more testing and refinement before it reaches broader clinical application, its development marks a significant step forward in non-invasive cancer diagnostics, potentially paving the way for better patient outcomes worldwide.
If successful in its future applications, J-PET could set a new global standard for cancer diagnostics, reducing the need for invasive procedures and making advanced diagnostics more accessible to hospitals and clinics worldwide.
