New method for fast spiral CT of trauma patients: RUSH CT

Abstract

Aim: The purpose of this study was to develop a fast scanning protocol for spiral CT of emergency trauma patients (RUSH-CT) in order to accelerate the diagnostic work-up. Method: In a consecutive series 446 trauma patients underwent spiral CT; of these, 51 emergency patients underwent a modified protocol (RUSH-CT) on a recent technology scanner (Somatom Plus 4). Scanning time was compared between the RUSH-CT and the regular protocols. Results: The average time for RUSH-CT, comprising one pilot scan and three spiral scans, including preparation time and monitor reading was 15 min (range 12–18 min; n = 51). Using regular organ protocols comprising two pilot scans and four spiral scans, the control group had an average scanning time of 35 min. In comparison to the conventional organ protocols, total scanning time could be reduced by the RUSH-CT by 57 % (P < 0.01). Conclusion: Fast spiral CT (RUSH-CT) significantly reduces the time needed for diagnostic work-up and allows early therapeutic intervention. CT diagnosis can be completed within the first 30 min after the patient's admission.
