Application neurochirurgicale de la tractographie et de la stimulation corticale et sous corticale by Pierre-Yves Borius( Book )

2 editions published in 2015 in French and held by 2 WorldCat member libraries worldwide

Tractography and intraoperative stimulation would optimize tumor resection preserving the quality of life. The principles of diffusion tensor, tractography and brain stimulation are shown. A study of tractography of optic radiation and validation on a lesion model was able to confirm the feasibility of the reconstruction. Among the tested algorithms, the most effective was the "Tensor Line" predicting a risk of quadrantanopia when more than 5% of the trajectories have an intersection with the lesion volume. The second part focused on the cognitive process of language whose translation by cortical stimulation during awake surgery for 7 bilingual patients. Twenty-six interference tasks area were found but none was specific to the translation, which is complex to study. Finally, the prospects for integration of these 2 techniques are discussed through three clinical cases

Apport de l'imagerie multimodale dans la caractérisation de la distribution de sources radioactives de 166Ho dans un contexte de dosimétrie en microcuriethérapie by Jonathan Tranel( Book )

2 editions published in 2019 in French and held by 2 WorldCat member libraries worldwide

The aim of targeted radiotherapy is the destruction of tumors thanks to radioactive sources located inside the body. Several sorts of targeted radiotherapy may be defined regarding properties of employed radioactive sources and the mode of administration: * The molecular radiotherapy (MRT) uses unsealed sources in a systemic way. * The selective internal radiation therapy (SIRT) uses unsealed sources (radioactive microspheres) of small dimensions delivered through the arteries, diffused at the vicinity of hepatic tumors. * The brachytherapy uses sealed sources directly located nearby the tumors or directly inside. The microbrachytherapy, considered as a hybrid between SIRT and brachytherapy, is under development. With this technique, microspheres are directly injected inside the tumor. This work is part of the TheraneaM project, which aimed to treat glioblastoma through microbrachytherapy with intracranial injection of radioactive microparticles with holmium-166. Our contribution concerns absorbed dose determination, namely the energy deposition in biological tissues. In order to optimize the calculation, the primary step before this calculation is the localization and quantification of the radioactive activity sources. This task is performed with acquisitions from quantitative imaging. Holmium displays all the properties of a multimodal agent, making its interesting for tissue quantification. Firstly, this work inquires the multimodal detection capability of holmium with three modalities (MRI, CT and SPECT) in order to obtain activity distribution maps. A quantification protocol is applied on a microbrachytherapy preclinical trial with intracranial injection of microparticles with holmium-166 into a glioblastoma pork model. The second part is dedicated to absorbed dose calculation, performed according to the MIRD formalism through algorithms implementation, with the consideration of tissues heterogeneities such as lungs and bone. A global study is undertaken with MRT treatments using 166Ho, 131I, 177Lu and 90Y at micro or macroscopic scale, in addition of the microbrachytherapy with holmium-166. The goal is a comparison of implemented algorithms performance regarding Monte Carlo simulation, taken as reference. These results might allow to express recommendations suitable for a clinical routine context. The final aim is to encourage global practice towards a precise and personalized dosimetry for targeted radiotherapy

Familiarity and recollection vs representational models of medial temporal lobe structures: A single-case study( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: Although it is known that medial temporal lobe (MTL) structures support declarative memory, the fact these structures have different architectonics and circuitry suggests they may also play different functional roles. Selective lesions of MTL structures offer an opportunity to understand these roles. We report, in this study, on JMG, a patient who presents highly unusual lesions that completely affected all MTL structures except for the right hippocampus and parts of neighbouring medial parahippocampal cortex. We first demonstrate that JMG shows preserved recall for visual material on 5 experimental tasks. This finding suggests that his right hippocampus is functional, even though it appears largely disconnected from most of its MTL afferents. In contrast, JMG performed very poorly, as compared to control subjects, on 7 tasks of visual recognition memory for single items. Although he sometimes performed above chance, neither familiarity nor recollection appeared fully preserved. These results indicate that extrahippocampal structures, damaged bilaterally in JMG, perform critical operations for item recognition; and that the hippocampus cannot take over that role, including recollection, when these structures are largely damaged. Finally, in a set of 3 recognition memory tasks with scenes as stimuli, JMG performed at the level of control participants and obtained normal indices of familiarity and recollection. Overall, our findings suggest that the right hippocampus and remnants of parahippocampal cortex can support recognition memory for scenes in the absence of preserved item-recognition memory. The patterns of dissociations, which we report in the present study, provide support for a representational account of the functional organization of MTL structures. Highlights: Unusual pattern of medial temporal lobe lesion. Dissociation between preserved recall but impaired recognition memory for single item. Impaired recognition memory for single item, preserved recognition memory for scenes. Familiarity and recollection results did not easily fit with dual-process accounts of the MTL but in this case are in agreement with representational account of the MTL
