BACKGROUND AND PURPOSE: Temporal bone CT is performed frequently in clinical
practice. At the same time, the eye lens are exposed to ionizing radiation without any useful …

BACKGROUND AND PURPOSE: Some recent studies on radiation lens injuries have
indicated much lower dose thresholds than specified by the current radiation protection …

BACKGROUND AND PURPOSE: To our knowledge, there has been no study that compares
the radiation dose delivered to the eye lens by 16-and 64-section multidetector CT (MDCT) …

Lenses are always exposed to radiation in brain computed tomography (CT) scans.
However, the lens dose can be reduced by excluding lens from scanning area by optimising …

Cataracts are the leading cause of blindness and visual disability worldwide. Of the known
contributing factors to this condition, ionising radiation is considered the primary concern in …

OBJECTIVE. The purpose of this study was to study different optimization methods for
reducing eye lens dose in head CT. MATERIALS AND METHODS. Two anthropomorphic …

Eye lenses lie within the radiation field during computed tomography (CT) procedures of the
brain. Therefore, patients are at risk of forming eye lens opacity when exposures exceed the …

Standard CT examinations of the orbit and the petrous bone were simulated with a tissue-
equivalent human skull phantom on a Somatom DR 2 scanner. The orientation of the scan …

Objective: Computed Tomography (CT) is the leading contributor to medical exposure to
ionizing radiation. Although the use of CT brain scans for patients with head injuries and …

Objectives: The aim was to define image quality and radiation exposure in the recently
introduced 320-row CT of the temporal bone (tb) in comparison to a 16-row tb CT. Methods …
