Le Spectral Photon CT Counting (SPCCT) est un projet européen visant à développer une nouvelle génération de scanner spectral en utilisant la technologie de comptage de photons. Ce projet multidisciplinaire est à l’interface de la médecine, la biologie et la technologie de pointe.
Ce projet inclut le développement de détecteurs et le traitement de données, mais aussi la reconstruction d’images, le développement d’agents de contraste spécifiques dédiés à un large éventail d’applications notamment en neurologie, mais aussi pour les maladies cardiovasculaires. Les applications en imagerie seront testées chez le petit animal, puis chez les grands animaux et l’homme, pendant les deux dernières années du projet.

Context / Contexte

Computed Tomography is the most widely used imaging method in the world and has transformed patient care. Spectral Photon Counting CT is a new imaging modality based on the usual CT concept with the key difference of energy resolving detector technology. The additional spectral information can be used for material separation and can deliver additional, new contrast with clinically relevant new information. The most important novel capability of Spectral CT is K-Edge imaging for selective and quantitative detection of specific elements including among others iodine, gold, bismuth, gadolinium or ytterbium. The full potential of Spectral CT can be exploited in combination with targeted contrast materials carrying a payload with a compatible K-edge.
Whereas today, the imaging agent market is dominated by contrast agents (65% of the market for 35% to SPECT/TEP tracers) for cardiovascular and brain imaging, development of new targeted imaging agents is anticipated. It is expected to continue its increase ($10.4 million of global pharmaceutics in 2010, and estimated $14.1 million in 2015). The main challenge is however to keep the application spectrum large enough for sales turnover. Imaging agents are also envisaged as new biomarkers and test companions for drug clinical trials, enabling faster transfer of innovative treatment to patients by a more personalized approach.

Objectives / Objectifs

The objective of the SPCCT is to develop and validate a widely accessible, new quantitative and analytical in vivo imaging technology combining Spectral Photon Counting CT and contrast agents, to accurately and early detect, characterize and monitor neurovascular and cardiovascular disease. This transversal project addresses one of the main challenges for molecular imaging agents, i.e. the scale-up process from lab chemistry to production to enabling successively proof-of-concept (PoC) studies, pre-clinical and clinical trials.

Expected impact and results / Impact et résultats attendus

This project will overcome the actual limitations of all the current available imaging modalities used in CV by developing a non-radioactive molecular imaging technique using SPCCT in human. This will be achievable with a high spatial resolution combined with the newly developed vascular inflammation specific contrast agent detected with high quality K-edge technique that can only be provided by a multispectral X-ray system.
Another important element of this project is that the concept can be further extended to other fields that need specificity and spatial resolution, in particular oncology.
Constrast agent production and PoC will be an essential step, but only for a limited number of candidates. The first step, human cell culture test will be obtained with a minimal production concern, but testing in small animals implies a scale-up for synthesis, with various issues depending on the platform (macromolecule,nanoparticles) and on the target moiety. After the termination of the project, effective translational research with first in-man evaluations can be anticipated in the neuro and cardiovascular diseases.
