Effect of digital edge-enhancement on the visibility of normal parenchymal lung markings.

Abstract：

:Digital 'conventional-like' (C-L) and edge-enhanced (E-E) posteroanterior chest roentgenograms of 42 healthy individuals were ranked twice (interval of at least 5 days) in the order of increasing lung parenchymal markings (a total of four rankings). This was done by three radiologists, two residents, one medical student and one radiographer. There was a good general consistency of rankings for both the C-L and E-E images. The correlation coefficients were best (median 0.600) (P < 0.05) between the consequent rankings of C-L images compared to the subsequent rankings of E-E images (median 0.440) and to the various combinations between the rankings of both kinds of images. Subtle differences in normal lung parenchyma could, therefore, generally (five of the seven observers) best be demonstrated in C-L images, but two observers managed best with the E-E images.

  • Imaging-therapy computed tomography with quasi-monochromatic X-rays.

    abstract：INTRODUCTION:Computed tomography (CT) is a widespread and highly precise technique working in the energy range around 50-100 keV. For radiotherapy, however, the MeV energy range enables a better dose distribution. This gap between diagnosis and therapy can be overcome by the use of a modified CT machine in combination ...

Endoscopy is the most precise method for the assessment of mucosal healing, but is considered overly invasive for patients with CD. In contrast, CT enterography (CTE) is less invasive, but little is known about the correlati...
