Lancet ;— Please try after some time. All statistical analyses were performed using the SPSS The scanning covered the length from the aortic arch to the cranial base with acaudal-to-rostral direction. PLoS One ;8:e Slender and normal weight patients imaged with 80 kV also produced images of diagnostic quality. In addition, computed tomography CT examination has been associated with an increased risk of cancer. Thought you might appreciate this item s I saw at Medicine. This scanning protocol can produce vascular and brain tissue images of high quality, as well as lower radiation dose for better patient safety.

A ring of electrodes may be placed in a single plane around the object, to define a two-dimensional problem, or in several layers of such rings, to define a three-dimensional problem. The use of computed tomography in pediatrics and the associated radiation exposure and estimated cancer risk. Typically, currents are injected into the object through electrodes placed on its surface, and the resulting electrode voltages are measured.
