Ability for visualization, reasons for nonassessable image, and diagnostic accuracy of 16-slice multidetector row helical computed tomography for the assessment of the entire coronary arteries.

It was demonstrated that 16-slice multidetector row helical computed tomography may permit more accurate assessment of entire coronary arteries, with a low rate of arteries unable to be evaluated. The detection of coronary artery stenoses with this modality was applicable to assessable segments.

[Physical imaging properties of a flat panel X-ray detector system].

We report the physical imaging properties of a flat panel detector (FPD) designed for radiographic imaging applications (Revolution XQ/i digital chest imaging system, G.E. Medical Systems).
