World’s First Three-Photon PET Scan Paves Way for New Cancer Diagnostic Techniques

The world’s first three-photon PET scan has been has been produced using the J-PET scanner that differs significantly from the currently used PET scanners, which only produce images based on two photons.

This innovative method was developed by an interdisciplinary and international group including physicists, chemists, electronic engineers, computer scientists, quantum information physicists as well as bio and medical physicists at Jagiellonian University (Kraków, Poland). The technology paves the way for new techniques of cancer diagnostics as well as possibilities of testing the symmetry between matter and antimatter.

The aim of the Jagiellonian PET project (J-PET) is to develop a device capable of scanning the entirety of a patient’s body at the same time. It could serve not only as a tool for locating cancer, but also determining the level of its malignancy and investigating the dynamics of metabolism and drug distribution. J-PET is a unique and innovative solution that will allow for the introduction of treatment methods based on precise diagnostics that will be continually improved at the JU Centre for Theranostics (a combination of therapeutics and diagnostics: a new approach to medicine focused on developing new technological solutions for simultaneous detection and treatment of diseases). The scientists have now created an image based solely on three-photon positronium annihilations. The ability to reconstruct these phenomena not only opens up new possibilities for unconventional techniques in PET imaging, but may also provide new perspectives for basic research.

In (E) 2022, a new mass developed in the left breast at the 6-o’clock position (arrow), with a (F) corresponding irregular mass at US (arrow). Subsequent US-guided core needle biopsy yielded invasive ductal carcinoma, grade 2. The deep learning 5-year risk scores gradually increased from 2.0 (2015) to 2.1 (2018), 3.4 (2019), 3.6 (2021), and 15.3 (2022).

The analysis only requires the patient to hold their breath for seven seconds for a sequence of images of their heart to be taken. The images are then analyzed and extracted into a waveform that can show the severity of PR. The new technique\\\'s detection accuracy of severe PR is 93%, with a sensitivity of 93% and a specificity of 94%. (Photo courtesty of Kyushu University/Yuzo Yamasaki)$
