Ionizing Radiation Exposure from Radiologic Imaging

Background The increased use of diagnostic imaging requiring the use of “ionizing radiation,” the rapidly expanding use of computed tomography in the emergency setting, the introduction of multi-detector CT units and newly reported concerns related to the human consequences of low-level radiation exposure have revitalized a long-standing concern over the quantification and management of an indi...

[Radiation exposure in computed tomography].

The axial dose profile of various scans of different CTs was determined to obtain specification on radiation geometry by collimation. The dose was measured "free-in-air" by thermoluminescent dosimeters at the axis of rotation. Considerable differences between the various CTs were observed. The scans of different CTs had narrow and wide fields. It seems to be possible to reduce the energy transm...

Exposure to low-dose ionizing radiation from medical imaging procedures.

BACKGROUND The growing use of imaging procedures in the United States has raised concerns about exposure to low-dose ionizing radiation in the general population. METHODS We identified 952,420 nonelderly adults (between 18 and 64 years of age) in five health care markets across the United States between January 1, 2005, and December 31, 2007. Utilization data were used to estimate cumulative ...
