The objective of the SPCCT project 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. Spectral Photon Counting Computed Tomography (SPCCT) is a new imaging modality, currently in development, with a totally new type of detection chain designed to provide high count-rate capabilities while offering energy discrimination with high spatial resolution of 200m. Based on this discrimination, SPCCT can detect and quantify accurately a large variety of atoms (including Gadolinium, Gold, Bismuth) by using the K-edge technique. SPCCT, by a more accurate, less invasive (in comparison with IVUS and coronary angiography) and reliable evaluation of vascular inflammation will allow earlier disease diagnosis such as plaque inflammation before rupture, leading to improved clinical decisions and outcomes. This will be achievable with a high spatial resolution combined to the newly developed vascular inflammation specific contrast agent detected with high quality K-edge technique that can only be provided by a multi-spectral X-ray system. The project will therefore provide a complete tool (acquisition system and specific probes) dedicated to CV imaging. It will finally contribute to: Improved early diagnosis of atherosclerosis, prevention of acute event (MI, stroke) and personalized preventive treatment; Improved management of patient presenting with an acute CV event and clinical validation of treatment efficiency; Sustainability and harmonization of healthcare systems, as costly disorders of heart failure and stroke-related disability would be better prevented and efficiently treated; Economic growth in the EU diagnostics sector, through the development of new targeted contrast materials for SPCCT by SMEs.

Cancer is one of the most devastating diseases the world is currently facing, accounting for 7.6 million deaths in 2008 (WHO). Cancer is usually detected through advanced medical imaging. Early detection is very important as it increases the chances of survival and the potential for full recovery. Further, The high level of sophistication in treating cancer has led to a new unsolved problem, the differentiation between treatment effect, regrowth or pseudo-progression of the tumour. Here, we aim to develop and bring to the clinic a potentially disruptive new technology to characterize and image glucose delivery, uptake and metabolism in cancer. Recently we managed to demonstrate the sensitivity of a technique, named glucose-based Chemical Exchange Saturation Transfer (glucoCEST), to detect native (-D-glucose) glucose uptake in tumours. In addition, recent developments have shown glucose analogues, such as 3-oxy-methyl-D-glucose (3OMG) can be used as potential non-metabolisable tracers using the same technique. In this proposal, we aim to bring the combination of native D-glucose and 3-oxy-methyl-D-glucose as a combined examination to the clinic to assess cancer glucose uptake and metabolism, thereby providing a cheap, widely available, more comprehensive, non-invasive alternative to nuclear medicine techniques currently used for cancer assessment within Europe.


The present invention discloses a process for the preparation of gadobenate dimeglumine complex in a solid form. In particular, said solid form is conveniently obtained by spray-drying a corresponding liquid suspension at a given temperature and concentration. The present invention is particularly advantageous for the industrial scale as the solid form may be obtained by employing water as a solvent, which is a non-toxic solvent, easy to handle and basically not requiring troublesome health or safety precautions.

A fluid delivery system may include a container that houses a medical fluid, a fluid pressurizing unit, and a fluid transfer set that transfers the medical fluid from the container to the fluid pressurizing unit. To validate the integrity and sterility of the fluid delivery system, the system may undergo testing protocols to evaluate the susceptibility of the system to pathogenic ingress, chemical degradation, and/or fluid cross-contamination between patient fluid delivery procedures. The testing protocols may help ensure that delivery system components used during multiple different fluid delivery procedures perform as well as if the components were replaced after each fluid delivery procedure.
