Vascular calcifications are frequent in chronic renal disease and are associated to significant cardiovascular morbidity and mortality. The long term predictive value of coronary artery calcifications detected by multi‐layer spiral computed tomography for major cardiovascular events was evaluated in non‐diabetic Caucasian patients on maintenance hemodialysis free of clinical cardiovascular dise...

  ABSTRACT   Background: While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk free. CT is a device with higher patient dose in comparison with other conventional radiological procedures. Is the reduction of exposures by requiring optimization of CT procedures [a principle concern in radiological protection]? In this study, the radiatio...

Consider the initial value problem for the three dimensional Navier-Stokes equations with rotation in the half-space R+ subject to Dirichlet boundary conditions as well as the Ekman spiral which is a stationary solution to the above equations. It is proved that the Ekman spiral is nonlinearly stable with respect to L2-perturbations provided the corresponding Reynolds number is small enough. Mor...

CONTEXT Colonic complications are rare but lethal events in acute pancreatitis. CASE REPORT We report the case of a 42-year-old man who suffered from a pancreatico-colonic fistula following a necrosectomy for severe pancreatitis; the fistula was demonstrated by spiral computed tomography using rectal water soluble contrast media. CONCLUSION Computed tomography with rectal contrast detects p...

Objective: To evaluate the diagnostic accuracy of the spiral-CT in patients with clinically suspected acute appendicitis. Material and Methods: A total of 124 patients referred for CT scan with suspected appendicitis between January 2005 and October 2006 were assessed for the appendiceal size and the presence of signs of appendicitis. The findings were correlated with surgical histopathology. R...

There is a paucity of scientific literature regarding the utility of computed tomography in the diagnosis of acute pericarditis. This report may be the first in the English language literature to document a diagnosis of clinically unsuspected acute pericarditis made using computed tomography. Spiral computed tomography has the capacity to diagnose acute pericarditis, since lymphadenopathy and h...
