| 520 | 3 | |a Purpose: The aim of this study was to evaluate the impact of a reduced tube potential (100kVp) for non-enhanced abdominal low-dose CT on radiation dose and image quality (IQ) in the detection of body packing. Methods: This retrospective study was approved by the local research ethics committee of our clinic. From March 2012 to July 2014, 99 subjects were referred to our institute with suspected body packing. 50 CT scans were performed using a 120kVp protocol (group A), and 49 CTs were performed using a low-dose protocol with a tube voltage of 100kVp (group B). Subjective and objective IQ were assessed. DLP and CTDIvol were analyzed. Results: All examinations were of diagnostic IQ. Objective IQ was not significantly different between the 120kVp and 100kVp protocol. Mean density of solid and liquid body packets was 210±60.2 HU at 120kVp and 250.6±29.7 HU at 100kVp. Radiation dose was significantly lower in group B as compared to group A (p<0.05). In group A, body packs were detected in 16 (32%) of the 50 patients. In group B, packets were observed in 15 (31%) of 49 patients. Laboratory analysis detected cocaine in all smuggled body packs. Conclusions: Low-tube voltage 100kVp MDCT with automated tube current modulation in screening of illegal drugs leads to a diagnostic IQ and significant dose reduction compared to 120kVp low-tube voltage protocols. Despite lower radiation dose, liquid and solid cocaine containers retain high attenuation and are easily detected. | |
