Deruelle, Tristan. „Magnetic Resonance Elastography : towards prostate cancer imaging and slow compression wave imaging in softtissues“. Electronic Thesis or Diss., Lyon, 2022. http://www.theses.fr/2022LYSE1068.
Der volle Inhalt der QuelleProstate cancer is the second most prevalent cancer in men worldwide. It is suspected when the PSA density is high or/and the superficial prostate feels hard during digital rectal examination. Multiparametric MRI is now recommended prior biopsy when detecting for cancer. However, image interpretation is challenging, even for specialists, and brings many false-positive. Elastography is a technique to assess tissue stiffness by inducing small vibrations. It could provide a 3D map of the stiffness of the prostate. We believe that MR elastography could complement the current multiparametric MRI. Given prostate location and consitution, wave propagation is difficult though. The current work presents the design of a non-invasive wave generation device for the prostate. Then, a new field separation algorithm is presented. This algorithm provides a better estimation of the stiffness, and the correction of artefact generated by common vibrators. Finally, this algorithm can have applications in porous media. Indeed, in poro-elastic materials, a slow compression wave propagates. We observe such a wave in an agar gel, in a foam phantom, and in vivo in human kidney graft. In addition to the classic shear wave velocity estimation, it is now possible to estimate the compression wave velocity. This is an additional piece of information that the operator can use in its diagnostic. In the future, more porous parameters could be derived

Der volle Inhalt der QuelleMagnetic Resonance Imaging of myocardical tissue. In patients with known or suspected cardiac desease, an "all-in-one" cardiac imaging modality should theoretically include morphological and functional analysis of the heart, but also information on myocardical tissue in order to detect its infiltration by abnormal tissues or substances and to study its perfusion and viability in ischemic disease. The specific magnetic properties with changes of relaxations times (and thereby increased or decreased signal intensities) induced by some tissues such as fatty infiltration, fibrosis, edema or inflammation allow a characterization of the myocardical tissue. Magnetic Resonance (MR) imaging also offers the potential for a complete functional study of the myocardium including contractility as well as perfusion and viability using cotrasts agents (Gadolinium-DTPA). The aim of this work was to demonstrate the ability of MR imaging to non-invasively characterize myocardical tissue and to assess its function. MR capacities of imaging the myocardical tissue have been applied to myocardical ischemia and to some specific cardiomyopathies

Der volle Inhalt der QuelleObjectives: Cardiac regenerative therapies have grown considerably over the past 10 years. Despite positive effects demonstrated in animals, the clinical benefits obtained in humans are still relatively modest. The objective of this work was to better understand the factors associated with implantation of stem cells through the cell detection techniques in magnetic resonance imaging (MRI) and to improve cardiac stem cell therapy in a murine model of myocardial infarction.Materials and methods: A protocol for cell detection with gradient echo T2* sequences in cardiac MRI in vivo and a method for detection of microvessels in cardiac MRI ex vivo with high resolution Susceptibility Weighted Imaging sequences (SWI) were developed and implemented for the study of vectorization of intravenously injected endothelial progenitors cells (EPC) and the integration and evaluation of the impact of mesenchymal stem cells (MSC) administered via cellularized fibrin patches. A permanent ligation of the left anterior coronary artery was performed in adult rats. The stem cells were magnetically labeled with iron oxide nanoparticles by endocytosis.Results: Cell detection imaging showed no cell implantation in the myocardium and no improvement in cardiac functional parameters after intravenous injection of EPC, despite the aid of magnetic vectorization (n = 16 rats). With a local administration of MSC via cardiac patches (n = 37 rats), the left ventricular ejection fraction (LVEF) was improved in cellularized patches groups compared to controls. Microvascular density was increased in the infarcted and peri – infarcted areas in cellularized patches groups compared to controls in immunohistochemistry and in MRI on SWI sequences. The MRI showed no migration of cells into the myocardium from the patch, as confirmed by immunohistochemistry and Perls staining. The persistence of MSCs on the epicardial surface at D21 after implantation and flow cytometry profiling of cytokines and growth factors produced by MSC argue for cell therapy effectiveness related to the secretion of paracrine factors by stem cells.Conclusion: Susceptibility imaging allows: (1) to study myocardial vessels on SWI sequences ex vivo and (2) to assess the implementation of stem cells on gradient echo sequences T2 * in vivo. These techniques have shown that cardiac patches act as a reservoir of soluble mediators which paracrinally target the angiogenesis in the treatment of heart failure in a murine model. This is in favor of a move towards “cell free” biomaterials containing only molecules of interest such as cytokines or growth factors to circumvent immunogenic and teratogenic constraints related to the use of stem cells

Der volle Inhalt der QuelleImaging allows HCC diagnosis without histological examination in case of typical imaging appearance (association of hypervascularization and washout). However this appearance is not sensitive for the diagnosis of early HCC. We showed the potential of functional imaging for characterization of nodules in the cirrhotic liver. In a rat model of multinodular cirrhosis, the diffusion MRI technique with oscillating gradients (OGSE), performed ex vivo, showed potential for identification of high grade dysplastic nodules and well differentiated HCC. The classic diffusion technique with pulsed gradients (PGSE) was able to separate HCC according to histological grade. The viscoelastic properties of HCC, evaluated by magnetic resonance elastrography in the same rat model and in patients, are different from those of the cirrhotic liver. The increase of loss modulus in HCC only in vivo suggests the importance of perfusion in determining mecanical properties. We have also shown that the delayed venous phase allowed superior washout detection compared to the portal venous phase in HCC explored by MRI. The inter-observer agreement was moderate. Finally, we have shown that viable tumor regions within liver tumors could be differentiated from fibrotic and necrotic regions by measuring the pure diffusion coefficient D, but not the apparent diffusion coefficient ADC, suggesting the applicability of D in tumor characterization and monitoring after treatment

Der volle Inhalt der QuelleScience has evolved since the 19th century. New tools have appeared such as optical microscopy which gives us the vision of cells and electronic microscopy which leads us into their hearts. The magnetic resonance imaging appeared in the seventies. Evolving over time, the MRI has taken us farther and farther into the secret depths of our brains. The possibility of observing the neuronal activity thanks to the functional imaging is a major evolution. This thesis will show the possibility we have to observe the activity of a single neuron without modification of its network thanks to the manganese enhanced magnetic resonance imaging technique. The study was done on the Aplysia at very high field magnet (17T). These animals are marine gastropod mollusks with a peculiarity: their neurons are of important size and can reach 1 mm in diameter. Their neurons are grouped into several ganglia. My study concerns the buccal ganglion which is the most studied ganglia in the research in electrophysiology. Before making any acquisitions, I had to conceive several microscopic coils adapted to the size of the ganglions. By reducing the size of the coils, the signal of the noise ratio increases. Then, a double coil allowing the simultaneous acquisition of two samples was built. This antenna required the construction of pre-amplifiers operating at 730 MHz. The first series of experiments helped observe the evolution of the neuronal activity according to different stimuli linked to the eating habits of the Aplysia in vivo. Thanks to the technique implemented, I shall show that, using MRI, it is possible to distinguish the activity of each neuron with respect to a stimulus. Afterwards, to continue this work, a second series of experiments was made in vitro. I studied the behavior of neurons when perfused with neural stimulators: dopamine and serotonin, both naturally present in the Aplysia. Generally, all neurons were activated but when observing them individually, I noticed some differences. Studies in electrophysiology will allow us to get a better understanding and a confirmation of the results of this study. The MEMRI technique can be used in the future to study various disorders such as compulsive behaviors, which are present in the Aplysia, and probably have the same origins as in humans, given that many fundamental processes (such as memory studied by Eric Kandel who he demonstrated that human and Aplysia memories works with the same mechanism) are similar between the two species
