Automatic Exposure Control During Computed Tomography Scans Of The Head: Effects On Dose And Image Quality, Stephen D. Osborne
Automatic Exposure Control During Computed Tomography Scans Of The Head: Effects On Dose And Image Quality, Stephen D. Osborne
Electronic Theses and Dissertations
Automatic exposure control (AEC) is effective at reducing potentially harmful radiation doses without sacrificing image quality for many types of computed tomography (CT) scans. However, there is a need for more information regarding the use of AEC for CT head scans. This study was conducted at Johnson County Community Hospital in Mountain City, TN. Preexisting adult CT head scans (n)60 were randomly selected to form 2 stratified samples, (n)30 each. One sample used a standard protocol, and the other used a protocol with a mA-modulated AEC system, Siemens CARE Dose 4D. Causal-comparative analyses were conducted, and …

Assessment Of Magnetic Resonance Imaging Safety: Allied Health Professional Clinical Competence, Tiffany Houser
Electronic Theses and Dissertations
Magnetic resonance imaging is a major advancement in the diagnostic imaging field. Most patients can tolerate an MRI however, there are some who are unable to complete a lengthy scan while lying completely still without sedatives or anesthesia. Non-MRI healthcare providers are trained to use equipment that is “unsafe” in the MRI suite due to the strong magnetic field. Staff who are not fully knowledgeable and trained in MRI safety measures can endanger staff and patients.
The purpose of this study was to determine the knowledge level of non-MRI healthcare providers regarding safety risks associated with MRI and to determine …
