X-ray computed tomography (CT) images are used for diagnostic and therapeutic purposes in various medical disciplines. In Japan, the number of facilities that own diagnostic CT equipment, the number of CT examinations and the number of CT scanners increased by ~1.4-fold between 2005 and 2011. CT operators (medical radiological technologists, medical physicists and physicians) must understand the effective doses for examinations at their own institutions and carefully approach each examination. In addition, the patients undergoing the examination (as well as his/her family) must understand the effective dose of each examination in the context of the cumulative dose...

Radiologic technologists often perform diverse roles throughout the workday, and they should have at least a minimal understanding of the responsibility and effects of these roles on the patient and organization. Although technologists can practice independently or as part of a work group, individuals should be prepared to improve patient care and to function as a servant, follower, and leader for the overall success of the organization. This article examines those roles, emphasizing servantship.

Hideo Nose, Junji Shiraishi
The use of digital radiographic systems has decreased the frequency of image retakes due to over/underexposure in general radiography. However, image retakes owing to patient positioning errors are likely to increase because of the convenience of a real-time image check on a console table. The purpose of the present study is to propose a novel radiographic examination procedure with an ultra-low-dose pre-test exposure that may be utilized to check patient positioning prior to taking an actual image, thereby reducing unnecessary patient exposure owing to image retakes...

BACKGROUND: Our health system orders a high number of STAT priority portable chest radiographs (62%) compared to Routine (35%) and Today (3%). Retrospective chart review of 1000 chest radiographs ordered with the STAT priority revealed that 38% of studies did not indicate clinical urgency. Given the high number or STAT priority portable chest radiographs ordered, prioritizing acquisition and interpretation of true STATs has become challenging for technologists and radiologists, leading to process inefficiencies, long turnaround times (TATs), communication failures, and patient-safety errors...
