Automatic detection of cardiac contours on MR Images using fuzzy logic and dynamic programming
1997
International audience; Abstract: This paper deals with the use of fuzzy logic and dynamic programming in the detection of cardiac contours in MR Images. The definition of two parameters for each pixel allows the construction of the fuzzy set of the cardiac contour points. The first parameter takes into account the grey level, and the second the presence of an edge. A corresponding fuzzy matrix is derived from the initial image. Finally, a dynamic programming with graph searching is performed on this fuzzy matrix. The method has been tested on several MR images and the results of the contouring were validated by an expert in the domain. This preliminary work clearly demonstrates the interes…
Comparison of the Enhancement Pattern of Hepatic Hemangioma on Magnetic Resonance Imaging Performed With Gd-EOB-DTPA Versus Gd-BOPTA
2019
Abstract Purpose To compare magnetic resonance imaging (MRI) findings with gadoxetic acid and gadobenate dimeglumine for the diagnosis of hepatic hemangiomas. Materials and Methods In this retrospective study, we included 26 hemangiomas (mean size was 14 mm ± 10 mm) in 19 patients (mean age 60 ± 14 years) scanned with both gadobenate dimeglumine MRI and gadoxetic acid MRI. For each patient, we collected multiple lesion variables including location, number, size and enhancement pattern on arterial, portal venous, 3-minute and hepatobiliary phases with both gadoxetic acid and gadobenate dimeglumine. The enhancement pattern with the two contrast agents was then compared. Results The typical en…
Hepatobiliary phase hypointensity predicts progression to hepatocellular carcinoma for intermediate-high risk observations, but not time to progressi…
2020
Purpose: To determine whether hepatobiliary phase hypointensity, enhancing “capsule” and size provide prognostic information regarding the risk of progression to hepatocellular carcinoma (HCC), as well as the time to progression, of intermediate to high risk observations ≥ 10 mm with arterial phase hyperenhancement (APHE). Method: This retrospective dual-institution study included 160 LR-3 and 26 LR-4 observations measuring more than 10 mm and having APHE in 136 patients (mean age [SD], 57 [11] years old). A composite reference standard of pathologic analysis and imaging follow-up was used. The prognostic performance of hepatobiliary phase hypointensity, enhancing “capsule” and size (cut-of…
Utility of Cardiac Magnetic Resonance to assess association between admission hyperglycemia and myocardial damage in patients with reperfused ST-segm…
2008
Abstract Aims to investigate the association between admission hyperglycemia and myocardial damage in patients with ST-segment elevation myocardial infarction (STEMI) using Cardiac Magnetic Resonance (CMR). Methods We analyzed 113 patients with STEMI treated with successful primary percutaneous coronary intervention. Admission hyperglycemia was defined as a glucose level ≥ 7.8 mmol/l. Contrast-enhanced CMR was performed between 3 and 7 days after reperfusion to evaluate left ventricular function and perfusion data after injection of gadolinium-DTPA. First-pass images (FP), providing assessment of microvascular obstruction and Late Gadolinium Enhanced images (DE), reflecting the extent of in…
Avoiding Pitfalls in the Interpretation of Gadoxetic Acid-Enhanced Magnetic Resonance Imaging
2016
Gadoxetic acid is extensively used in the following 3 main clinical situations: characterization of small nodules in patients with cirrhosis, preoperative staging of liver metastases, and characterization of incidentally discovered focal liver lesions. Owing to the rapid entry of gadoxetic acid into hepatocytes, the traditional features of liver tumors are modified on magnetic resonance (MR) imaging, especially during delayed phase sequences. Thus, although the added value of gadoxetic acid for the detection and characterization of focal liver lesions is now clear, its unique pharmacokinetics as well as the presence of mimicking and atypical lesions may lead to misdiagnoses. The goal of thi…
Vicent Garcia, poeta europeu
2012
Després de repassar la bibliografia crítica i els textos poètics derivats, es procedeix a l’anàlisi d’un conegut sonet de Francesc Vicent Garcia, rector de Vallfogona (1578/1579-1623): «A una hermosa dama de cabell negre, que es pentinava en un terrat ab una pinta de marfil», que comença «Ab una pinta de marfil polia», en què l’autor mostra una habilitat poètica excepcional. S’insereix després el text en el seu context estètic i històric, el barroc europeu, i finalment se’l compara amb una sèrie de sonets equivalents, sobre el mateix motiu, produïts per autors castellans, portuguesos, italians i francesos. S’hi conclou que el de Garcia és molt original, tot i la forta codificació de la sèri…
Bilateral Monopoly: A Contribution by Francesco Ferrara
2009
In this paper, we propose an interpretation of the application of "cost of reproduction" of Francesco Ferrara to the exchange between two agents to highlight its relevance for the theory of bilateral monopoly. In the Teoria delle Mercedi (1863), Ferrara gives a numerical example to explain price determination in the exchange between one buyer and one seller. Here, this example is translated into a mathematical model that reproduces the fundamental issues of the neoclassical debate on the indeterminacy of price in the Cournot model (1938), and anticipates the solutions proposed by Edgeworth (1881) at the end of this debate.
S2-lukija tulkitsijana selkomukautetun kaunokirjallisuuden lukupiirissä

This article discusses reading circles of adult Finnish as a second language (L2) readers. The books that were read and discussed in the circles were easy-to-read fiction. The study focuses on how the readers interpret what they read and what kind of support they need for their interpretations. The analysis utilizes the concept of scaffolding, used in socio-cultural learning theory. The readers’ reading stances vary from what is literally said in the text to creating their own interpretations of the hidden meanings of the text. The latter are not very common in the reading circles, although many participants express a wish to create and discuss interpretations too. The analysis shows that i…
Los principios generales del derecho en la interpretación. (Una aproximación desde J. Bms. Vallet de Goytisolo)
2011
RESUMENEl artículo comienza haciendo mención al papel de la interpretación en el campo del Derecho así como su alcance en esta área. A continuación, se analiza el concepto de principio general del Derecho. Una vez centradas estas cuestiones, el artículo continúa con una panorámica general de la visión de Vallet de Goytisolo en el tema que se plantea, haciendo una pequeña referencia a la particularidad de la aplicación de la analogía iuris en la proyección de los principios generales del Derecho. La exposición finaliza con unas notas a modo de conclusiones ABSTRACT The article begins by explaining the role and scope of interpretation in Law. Next, it explores the concept of General Principle…
Supporting fine-grained generative model-driven evolution
2010
Published version of an article in the journal: Software and Systems Modeling. Also available on SpringerLink:http://dx.doi.org/10.1007/s10270-009-0144-1 In the standard generative Model-driven Architecture (MDA), adapting the models of an existing system requires re-generation and restarting of that system. This is due to a strong separation between the modeling environment and the runtime environment. Certain current approaches remove this separation, allowing a system to be changed smoothly when the model changes. These approaches are, however, based on interpretation of modeling information rather than on generation, as in MDA. This paper describes an architecture that supports fine-gra…
