Cette thèse traite de certains aspects analytiques liés aux coefficients de Fourier des formes modulaires de poids demi-entier. On étudie en particulier deux problèmes a priori bien différents mais que l’on reliera.Tout d’abord, on s’intéresse aux sommes des coefficients d’une forme cuspidale de poids demi-entier dans les progressions arithmétiques. Un tel problème fut étudié précédemment dans un article de Fouvry, Ganguly, Kowalski et Michel mais dans le cas d’une forme de poids entier. Les auteurs montrent notamment que, dans un certain régime de convergence, on a une équirépartition gaussie

Abstract:

Cancer is one of the major causes of worldwide mortality. Imaging plays a vital role in the staging, follow-up, and evaluation of therapeutic response in cancer patients. Whole-body (WB) magnetic resonance imaging (MRI), as a non-ionizing imaging technique, is a promising procedure to assess tumor spreading in a single examination. New MRI technological developments now enable the application of diffusion-weighted imaging (DWI) of the entire body. DWI reflects the random motion of water molecules and provides functional information of body tissues. DWI can be quantified with the use of the app

The construction and application of the FV-WENO scheme and codes will be described. Also the effects of the grid coefficients as well as the effect of the Gaussian Quadrature on the solution have been tested and discussed. WENO schemes are high order accurate schemes designed for problems with piecewise smooth solutions containing discontinuities. The key idea lies at the high approximation level, where a convex combination of all the candid

Trabalho final de mestrado integrado em Medicina área científica de Imagiologia, apresentado á Faculdade de Medicina da Universidade de Coimbra<br>Purpose: To measure apparent diffusion coefficient (ADC) values of liver parenchyma and focal hepatic lesions (FHL), investigate the utility of ADC for the differential diagnosis of hepatic findings, and determine the influence of region of interest (ROI) characteristics in the overall ADC measurements. Materials and Methods: Ninety-three patients (47 men, 46 women; mean age, 58 years) with at least one FHL ≥ 10 mm, or parenchyma abnormalities,

Trabalho final de mestrado integrado em Medicina, apresentado à Faculdade de Medicina da Universidade de Coimbra.<br>Purpose: To assess the relevance of diffusion-weighted imaging (DWI) in the hepatocellular carcinoma (HCC) detection as a stand-alone procedure or in combination to conventional magnetic resonance imaging (MRI). Methods: Medical records from nineteen patients with pathological confirmation of HCC, who have been submitted to conventional MRI and DWI in a time frame 3 months prior and 3 months after diagnosis, were retrospectively reviewed. For each patient, apparent diffusion

Abstract:

碩士<br>國立彰化師範大學<br>統計資訊研究所<br>97<br>Many studies in medical, industry and business fields commonly use questionnaires and diagnoses reported by different raters or instruments to evaluate the agreement of multiple ratings. The most popular indices of agreement for a categorical response are the kappa measures, Cohen’s kappa for binary outcomes and weighted kappa for ordinal outcomes (Cohen 1960, 1968). However, when raters assess the same observation on two or more occasions, these ratings are dependent, and, therefore one must take into account the correlation between the kappa estimates for m

碩士<br>國立臺灣大學<br>生醫電子與資訊學研究所<br>103<br>Intravoxel incoherent motion diffusion-weighted magnetic resonance imaging (IVIM DW MRI) is a technique that can quantitatively assess both the water molecular diffusion in static tissues (true diffusion coefficient, D) and the incoherent motion of blood water molecules in capillary networks due to perfusion (pseudo-diffusion coefficient, D*). However, D* value in liver parenchyma appears to be of high uncertainty among literatures. The aim of this study is to determine the reproducibility of D* in normal liver at 3T, considering SNR, b value sampling numb

Abstract:

Breast cancer is a major global health problem and the most common form of cancer among women. Major advances in the technologies of imaging provide improved detection and sensitivity with fewer unnecessary biopsies. Commonly used imaging modalities include mammography, ultrasonography, magnetic resonance imaging (MRI), scintimammography, single photon emission computed tomography (SPECT) and positron emission tomography (PET). The current study is focused on breast MRI imaging, especially one of the most promising recent techniques, i.e. the Diffusion Weighted Imaging breast MRI (DWI). DWI
