Use of computed tomography (CT) as a medical diagnostic imaging tool has increased in recent decades because of its technical advances in data acquisition speed and image reconstruction technology. The increased reliance on CT was accompanied by increased patient exposure to ionizing radiation, however, and concerns among radiologic professionals and the public regarding CT dose resulted in increasing attention to dose reduction. Research and education efforts have addressed many of these concerns, and radiologic technologists play a critical role in optimizing image quality and radiation dose in CT for individual patients and for the industry in general.

- Radiol Technol 2014 Jul; 85(6):655-82.
Radiologic technologists are likely to image a wide variety of foreign bodies in the course of their careers and should know which techniques work best in different circumstances. This article reviews the strengths and limitations of radiography, ultrasonography, computed tomography, and magnetic resonance imaging for visualizing foreign bodies and describes the imaging appearance of some common foreign-body materials, including glass, metal, wood, plastic, stone, and rubber. Several special types of foreign bodies also are discussed, such as medical devices, concealed packets of illegal drugs, and self-embedded items. The intraoperative role of imaging during removal of foreign bodies also is described.
- Hospital-Acquired Methicillin-Resistant Staphylococcus aureus: Status and Trends. [Journal Article]
- Radiol Technol 2014 Jul; 85(6):623-48.
Methicillin-resistant Staphylococcus aureus (MRSA) has been a pathogen of serious concern to both the health care and public health communities since the 1960s. This article focuses on the most serious strains of MRSA, hospital-acquired/health care-associated MRSA. Signs and symptoms of MRSA infection are described, in addition to the modes of transmission, laboratory techniques for identifying MRSA, and treatment options. Global MRSA rates are presented and prevention technologies are discussed. Finally, multiagency suggestions for eradicating MRSA are presented, such as strict adherence to standard contact precautions and hand hygiene practices within the medical community.
- Effects of radiographic techniques on the low-contrast detail detectability performance of digital radiography systems. [Journal Article]
- Radiol Technol 2014 Jul; 85(6):614-22.
To evaluate the effects of the radiation exposure factors kilovolt peak and tube current time (milliampere seconds) on the low-contrast detail detectability performance of 3 types of planar digital radiography systems. Detectability performance of an imaging system refers to its ability to detect and present the low-contrast details of organs in the acquired image. The authors also compare detectability performance between computed radiography, indirect digital radiography, and direct digital radiography by evaluating low-contrast details of the obtained images.A low-contrast detail phantom was inserted within 10-cm thicknesses of Perspex plastic sheets. The images were obtained with various kilovolt peak and milliampere second settings for each of the 3 digital radiography systems. Artinis CDRAD Analyser software was used to score the images and calculate the inverse image quality figure (IQFinv).The higher milliampere second levels in each kilovolt peak selection resulted in higher IQFinv in computed radiography and indirect and direct digital radiography. IQFinv values significantly increased in indirect digital radiography with increasing kilovolt peak in only 1 and 2 mAs. There were insignificant differences in IQFinv values when altering kilovolt peak in each milliampere second level in direct digital radiography. The indirect digital radiography system generally demonstrated better detectability performance than computed radiography and direct digital radiography. However, direct digital radiography demonstrated better detectability performance than indirect digital radiography at lower kilovolt peak and milliampere second settings, as did computed radiography at lower kilovolt peak settings.Higher milliampere second settings increase photon count, which results in a higher signal-to-noise ratio and thus increased detectability. Lower milliampere second settings increase noise level on images, which increases the risk of diagnostic detail loss. Changing the kilovolt peak at the different milliampere second settings essentially did not affect the IQFinv of the different digital radiography systems.Increasing milliampere seconds in all digital imaging systems generally improves detectability performance. However, altering the kilovolt peak setting does not significantly change the IQFinv and detectability of objects in a digital radiograph. Imaging system selection should be based on typical radiographic examinations. Indirect digital radiography systems are better for studies that require higher kilovolt peak, such as large organs, and direct digital radiography is better for studies that require low kilovolt peak, such as small organs and mammography, which is used to examine fine tissue details.
