Résumé

Background: Quantification of the T2 signal by means of T2 mapping in acute pancreatitis (AP) has the potential to quantify the parenchymal edema. Quantitative T2 mapping may overcome the limitations of previously reported scoring systems for reliable assessment of AP. Purpose: To evaluate MR-derived pancreatic T2 mapping values in AP and correlate them with markers of disease severity. Study Type: Prospective single-center study. Population: 76 adults with AP (20-91 years, females/males: 39/37). Field Strength/Sequence: Fat suppressed multiecho spin-echo prototype sequence to quantify T2 signal at 3T MRI. Assessment: The severity of AP was assessed clinically, biologically, and by contrast-enhanced CT (CECT) performed 48-72 hours after symptom onset. MRI was then performed

Pancréatite aiguë

La pancréatite aiguë est une maladie consistant en une inflammation rapide du pancréas. En fonction de sa gravité, elle peut avoir de graves complications et une grande mortalité malgré le traitement. Alors que les cas modérés se normalisent grâce à des mesures conservatives ou à l’endoscopie, les cas graves nécessitent une chirurgie (souvent plus d’une intervention) pour endiguer l’évolution de la maladie. La maladie était connue avant le , mais son mécanisme non élucidé.

Test de Student

En statistique, un test de Student, ou test t, désigne n'importe quel test statistique paramétrique où la statistique de test calculée suit une loi de Student lorsque l’hypothèse nulle est vraie. gauche|vignette|Façade de la brasserie historique Guinness de St. James. vignette|William Sealy Gosset, qui inventa le test t, sous le pseudonyme Student.

Pancréatite

Pancreatitis is a condition characterized by inflammation of the pancreas. The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. There are two main types: acute pancreatitis, and chronic pancreatitis. Signs and symptoms of pancreatitis include pain in the upper abdomen, nausea and vomiting. The pain often goes into the back and is usually severe. In acute pancreatitis, a fever may occur, and symptoms typically resolve in a few days.

Weak correlations between visual abilities in healthy older adults, despite long-term performance stability

Michael Herzog, Simona Adele Garobbio

Using batteries of visual tests, most studies have found that there are only weak correlations between the performance levels of the tests. Factor analysis has confirmed these results. This means that a participant excelling in one test may rank low in ano ...
