Garibaldi Franco (Italian Institute of Health and INFN - Roma1, gr. Sanita')11/05/2006, 08:30S5-S6 medecineoralProstate cancer is the most frequently occurring cancer in men. Considerable improvements have been implemented in the diagnosis with the Magnetic Resonance Imaging (MRI) technique, and with nuclear medicine techniques of scintigraphy and Positron Emission Tomography (PET). Unfortunately, the presently used standard clinical nuclear medicine imagers for single gamma imaging (gamma...Go to contribution page

Dr Francesco Cusanno (Istituto Nazionale Fisica Nucleare)11/05/2006, 09:00S5-S6 medecineoralDedicated high resolution detectors are needed for detection of small tumors by molecular imaging with radionuclides. Absorptive collimation typically used for imaging single photon emitters, results in a strong reduction in efficiency. System based on electronic collimation is offering higher efficiency but is complex and expensive. For these reasons, the simulations and measurements...Go to contribution page

Prof. Joao Varela (LIP)11/05/2006, 09:15S5-S6 medecineoralThe Clear-PEM scanner for positron emission mammography under development is described. The detector is based on pixelized LYSO crystals optically coupled to avalanche photodiodes (APD) and readout by a fast low-noise electronic system. A dedicated digital trigger and data acquisition system is used for on-line selection of coincidence events with high efficiency, large bandwidth and...Go to contribution page

Dr Claude Comtat (Frédéric Joliot Hospital Facility, CEA/DSV/DRM, Orsay, France)11/05/2006, 09:30S5-S6 medecineoralHigh resolution PET imaging is now a well established technique not only for small animal, but also for human brain studies. The ECAT HRRT brain PET scanner (Siemens Molecular Imaging) is characterized by an effective isotropic spatial resolution of 2.5 mm, about a factor of 2 better than for state-of-the-art whole-body clinical PET scanners. Although the absolute sensitivity of the HRRT...Go to contribution page

Dr Eric Guedj (Service Central de Biophysique et Médecine Nucléaire CHU Timone APHM)11/05/2006, 09:45S5-S6 medecineoralFibromyalgia (FM) syndrome is a chronic pain illness characterized by widespread musculoskeletal aches, pain and stiffness, soft tissue tenderness, general fatigue and sleep disturbances, without clinically demonstrable peripheral nociceptive cause. If a psychogenic trouble has been initially postulated, recent fMRI studies clearly demonstrated a global dysfunction of central pain...Go to contribution page

Prof. Dimitris Maintas (Institute of Isotopic Studies, Athens)11/05/2006, 10:00S5-S6 medecineoralThe use of external positron emitting sources or single photon emitting sources at energies similar to annihilation photons seems to give acceptable results permitting the quantification of PET data. The attenuation correction based on CT data generates artefacts around metallic prostheses, after use of contrast media and in the pulmonary region near calcifications and on dense...Go to contribution page

Prof. Jean-Philippe VUILLEZ (CHU GRENOBLE)11/05/2006, 11:00S5-S6 medecineoralInternal targeted radiotherapy consists in the in situ irradiation of tumour cells using an appropriate radiolabelled agent. Such an agent should be sufficiently tumour-specific in order to accumulate and be retained for a long time in the tumour, while its elimination from normal tissues should occur quickly. Such an approach has already proved to be efficient for the treatment of...Go to contribution page

Dr Slobodan Devic (McGill Univeristy)11/05/2006, 11:30S5-S6 medecineoralPurpose: To test the feasibility of FDG based PET/CT data on target volume delineation in radiotherapy treatment planning of NSCLC patients, and impact of these outlined biological target volumes (BTV) for IMRT treatment. Materials and methods: Patient diagnosed with non-operable NSCLC in the right upper lobe had a 3D conformal planning based on CT data with our hypo-fractionated...Go to contribution page

Neal Clinthorne (University of Michigan)11/05/2006, 11:45S5-S6 medecineoralSeveral years ago we presented the idea that PET resolution better than the intrinsic range of the positron at good sensitivity was achievable by placing a high resolution detector—ideally taking the form of a small diameter ring—within the bore of a conventional PET detector ring (J. Nucl. Med. Supp. 2000, 41(5):20P, 2001, 42 (5):55P, 102P). While we examined constructing the inner...Go to contribution page

Dr Philippe Tellier (CMNA Clinique Sainte Catherine)11/05/2006, 12:00S5-S6 medecineoralBackground. Whole body exercise thallium scintigraphy can detect silent or symptomatic PAD. Whether exercise thallium perfusion muscular asymmetry in the legs has prognostic value is unknown. Methods and Results –Three hundred fifty-eight consecutive patients (mean age 58.8±10.2 year; coronary artery disease, 202/358; 56.4 %) were prospectively followed after thallium 201...Go to contribution page

Prof. Francesco Scopinaro (University "La Sapienza", Rome, Italy)11/05/2006, 12:15S5-S6 medecineoralAim. Radio-isotope guidance is useful in several fields of surgery, such as sentinel node biopsy, parathyroid adenoma and of some neuroendocrine tumours, withdrawal of laterocervical lymph nodes invaded by thyroid cancer. Radioguided surgery (RGS) is generally performed with a gamma probe (GP) providing an acoustic signal proportional to the detected activity. The Imaging Probe (IP) is...Go to contribution page
