ORBi Open Repository and Bibliography (173,725 recursos)
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

104. New method for 3D reconstruction of the human cranial vault from CT-scan data - Laurent, Cédric; JOLIVET, Erwan; HODEL, Jérôme; DECQ, Philippe; SKALLI, Wafa
This study presents a new method for the 3D reconstruction of the human cranial vault from routine Computed Tomography (CT) data. The reconstruction method was based on the conceptualization of the shape of the cranial vault with a parametric description. An initialization was first realized with the identification of anatomical landmarks and contours on Digitally Reconstructed Radiographs (DRR) in order to obtain a pre-personalized reconstruction. Then an optimization of the reconstruction was performed to segment the internal and external surfaces of the cranial vault for thickness computation. The method was validated by comparing final reconstructions issued from our approach and from a manual sliceby- slice segmentation method...

106. PET radiopharmaceuticals in Europe : Current use and data relevant for the formulation of summaries of product characteristics (SPCs) - Meyer, G. J.; Waters, S. L.; Coenen, H. H.; Luxen, André; Maziere, B.; Langstrom, B.
The increasing use of radiopharmaceuticals for positron emission tomography (PET) has come to the attention of regulatory bodies. In order to help authorities in all aspects, the EANM has formed a task group for licensing PET radiopharmaceuticals; this group has surveyed the use of these compounds in Europe by a questionnaire. The number of PET centres that responded to the questionnaire was 26, which included more than 90% of the larger European PET centres. The survey showed that 2-[18F]fluoro-2-deoxyglucose is by far the most important PET radiopharmaceutical with more than 200 applications per week, followed by [15O]water, [15O]carbonmonoxide, [13N]ammonia, [11C]-l-methionine,...

108. (111)Indium-oxine labelling for evaluating the homing process of autologous osteoblasts implanted percutaneously in atrophic nonunion fractures. - Hauzeur, Jean-Philippe; Bernard, Claire; Egrise, Dominique; Kurth, William; Van Cauwenberge, Henry; Lechanteur, Chantal; Gillet, Philippe; Beguin, Yves; MALAISE, Michel; HUSTINX, Roland
PURPOSE: The aim of the study was to control the in vivo localisation of implanted cells in cell-based therapies. Labelling cells with (111)indium-oxine is one of the most interesting methods proposed. We evaluated this method in the setting of autologous osteoblast implantation in nonunion fractures. METHODS: An in vitro study of osteoblasts was conducted after (111)indium-oxine labelling. Radioactivity retention and viability, proliferation and the ability to produce alkaline phosphatase were evaluated in a seven-day culture. In vivo labelling of implanted osteoblastic cells was conducted during a therapeutic trial of atrophic nonunion fractures, with the leakage outside the nonunion site and...

111. Stereotaxic Needle-Core Biopsy and Fine-Needle Aspiration Biopsy in the Diagnosis of Nonpalpable Breast Lesions: Controversies and Future Prospects - Lifrange, Eric; Kridelka, Frédéric; Colin, Claude
OBJECTIVE: To determine the advantages and limitations of a combined stereotaxic fine-needle aspiration biopsy and needle-core biopsy in the diagnosis of 353 nonpalpable breast lesions with special attention given to the collection of follow-up data. METHODS AND MATERIAL: 353 nonpalpable breast lesions underwent 'one pass' stereotaxic fine-needle aspiration (21 gauge needle) and needle-core biopsy (18 gauge needle) at our institution from January 1990 to October 1993. Stereotaxic biopsies were carried out by means of an 'add-on unit'. Surgical biopsy was usually recommended for highly suspicious radiologic patterns and/or needle biopsy reports classified as atypical or malignant. In all other cases...

112. Performance Measurements of the microPET FOCUS 120 for Iodine-124 Imaging - Taleb, Dounia; Bahri, Mohamed Ali; Seret, Alain
This study aimed to evaluate the performance of the microPET FOCUS 120 for 124I in terms of counting rate capability and image quality using the NEMA NU 4-2008 methodology. Scanner sensitivity was measured for 124I for comparison and reached 75 cps/kBq, respectively, with the usual 350-650 keV energy window (EW) and 6 ns time window (TW). The noise equivalent count rate (NECR) index was defined as: NECR = RT2/(RP+RGP) (T = true, P = prompt, GP = γ-prompt). A rat phantom maximum NECR of 48 kcps was obtained for the 250-590 keV EW with 6 ns TW. An almost identical...

114. Percutaneous stereotactic en bloc excision of nonpalpable breast carcinoma: a step in the direction of supraconservative surgery. - LIFRANGE, Eric; Dondelinger, Robert; Foidart, Jean-Michel; Bradfer, J.; Quatresooz, Pascale; COLIN, Claude
Recently, the advanced breast biopsy instrumentation (ABBI) system has been introduced as an alternative to conventional breast biopsy techniques. This study was prospectively conducted to evaluate the potential of the ABBI method in locoregional management of a consecutive series of patients with nonpalpable mammographically detected breast carcinomas. Sixty-one consecutive patients underwent an ABBI procedure as a first step before possible surgery for nonpalpable breast lesions that would in any case require complete excision. For the 27 patients in whom the ABBI biopsy revealed malignancy further surgery was recommended, including re-excision of the biopsy site and axillary dissection in cases of...

115. Stereotactic breast biopsy with an 8-gauge, directional, vacuum-assisted probe: initial experience. - LIFRANGE, Eric; Dondelinger, Robert; Quatresooz, Pascale; Vandevorst, Geraldine; Colin, Claude
This study was prospectively conducted to assess the feasibility, safety and accuracy of an 8-G directional vacuum-assisted biopsy (DVAB) probe in the diagnostic management of nonpalpable breast lesions (NPBL). Of 170 planned procedures which were indicated for investigation of BI-RADS category-3 to category-5 lesions, 153 were performed in 138 consecutive patients. The probe was targeted by the stereotactic unit of a prone table (United States Surgical Corporation, Norwalk, Conn.; and Lorad, Danbury, Conn.). Four to 18 (mean 8) core specimens were obtained for each lesion. In case of complete removal of the lesion, a localizing clip was deployed at the...

117. Hormonosubstitution postmenopausique et risque de cancer mammaire: une mise a jour. - van den Brule, F.; LIFRANGE, Eric; Pintiaux, A.; Foidart, Jean-Michel; Gaspard, Ulysse
Numerous studies have examined the risk of breast cancer in patients with postmenopausal hormone substitution. Most of these studies are retrospective, and a few recent studies are prospective. The observed results present with weak variations from baseline and major heterogeneity. Some studies highlight a slightly increased relative risk of breast cancer. A reanalysis of 51 studies demonstrates a relative risk of 1.35 for developing breast cancer during hormone substitution, with a 2.3% increased risk per year of use. Recently, the results of the WHI study have shown a slight increase of some risks of disease, including breast cancer (relative risk,...

118. En Bloc Excision of Nonpalpable Breast Lesions Using the Advanced Breast Biopsy Instrumentation System: An Alternative to Needle Guided Surgery? - Lifrange, Eric; Dondelinger, R. F.; Fridman, Viviana; Colin, Claude
This study was prospectively conducted to evaluate the clinical potential of the advanced breast biopsy instrumentation (ABBI) system as an alternative to needle localization and open surgery in the management of nonpalpable breast lesions (NPBL). One hundred and eighty-six consecutive patients were referred for management of NPBL. Thirty-six underwent an ABBI procedure, offered as a first step before possible surgery for lesions which would in any case have required complete excision. The 18 patients with a malignant ABBI biopsy underwent re-excision of the biopsy site and axillary dissection was carried out in cases of infiltrating carcinoma. The other 150 patients...
