Radiation dose to the thyroid gland and breast from multidetector computed tomography of the cervical spine: does bismuth shielding with and without a cervical collar reduce dose?

Abstract

PURPOSE This study aimed to assess the radiation dose reduction that could be achieved using an in-line bismuth shielding over the thyroid gland and breast and to determine the effect of a cervical spine collar on thyroid dose reduction and image noise when performing computed tomography of the cervical spine using automatic tube current modulation… (More)
