Introduction

The threat of a terroristic attack with a Radiological Dispersal Device is imminent and comes along with an immense challenge especially regarding medical treatment of combined injuries with incorporated radioactive fragments [1,2,3]. In such scenarios the identification and surgical exploration of radioactive fragments is a major issue to prevent further radiation induced effects like wound healing disorders, onset of acute radiation syndrome, and as a late effect cancer [4,5]. However, in a usual emergency setting it is unclear how this task can be achieved. Within this study we evaluated the feasibility of different radiological methods to identify and locate an incorporated radioactive fragment.

PhotoFig. 2: Cs137 sealed in plastic in axial orientation (arrow/asterisk, A-D) and matching sham controls (E-H) scanned with different CT scanners and protocols, respectively. Cs137 source was placed in quadrant 4 and showed sham control in quadrant 1 (Setup 2). PhotoFig. 1: Depicted are Cs137 sources in axial orientation (arrow, A-D) and matching sham controls (E-H) scanned with different CT scanners and protocols, respectively. Cs137 source was placed in quadrant 4 and showed sham control in quadrant 5 (Setup 1).
