Actinomycosis is a rare, chronic, slowly progressive granulomatous disease caused by filamentous gram-positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). It has become a rare condition because of the widespread use of antibiotics. When clinical symptoms are not typical, diagnosis of this condition becomes difficult. This report describes a case involving an 82-year-old woman who was diagnosed with actinomycotic osteomyelitis of the mandible using matrix assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS)...

Indirect immunofluorescence (IIF) is considered by the American College of Rheumatology (ACR) and the international consensus on ANA patterns (ICAP) the gold standard for the screening of anti-nuclear antibodies (ANA). As conventional IIF is labor intensive, time-consuming, subjective, and poorly standardized, there have been ongoing efforts to improve the standardization of reagents and to develop automated platforms for assay incubation, microscopy, and evaluation. In this study, the workflow and performance characteristics of a fully automated ANA IIF system (Sprinter XL, EUROPattern Suite, IFA 40: HEp-20-10 cells) were compared to a manual approach using visual microscopy with a filter device for single-well titration and to technologist reading...

After years of establishment of computed radiography (CR) and digital radiography (DR), manufacturers have introduced exposure indicator/index (EI) as a feedback mechanism for patient dose. However, EI consistency is uncertain for CR. Most manufacturers recommended EI values in a range of numbers for all examination, instead of giving the exact range for a specific body part, raising a concern of inappropriate exposure given to the patient in clinical practice. The aims of this study were to investigate the EI consistency in DR systems produced in constant exposure parameters and clinical condition, and to determine the interaction between the anatomical part and EI...

BACKGROUND: Several studies have shown a linkage between intraplaque neovascularization (IPN) and plaque instability. Although contrast-enhanced ultrasonography (CEUS) may help visualize IPN in the carotid artery, its benefits are limited in Japan, where there is no health insurance coverage for contrast agents in medical imaging. Superb microvascular imaging (SMI), however, enables the depiction of low-velocity blood flow. The current study compares the diagnostic accuracy of SMI and CEUS in the evaluation of IPN...

Traditionally, radiologists have been responsible for the protocol of imaging studies, imaging acquisition, supervision of imaging technologists, and interpretation and reporting of imaging findings. In this article, we outline how radiology needs to change and adapt to a role of providing value-based, integrated health-care delivery. We believe that the way to best serve our specialty and our patients is to undertake a fundamental paradigm shift in how we practice. We describe the need for imaging institutes centered on disease entities (eg, lung cancer, multiple sclerosis) to not only optimize clinical care and patient outcomes, but also spur the development of a new educational focus, which will increase opportunities for medical trainees and other health professionals...

There are two aspects of immunohistochemistry (IHC) that are relevant to practicing pathologist: (1) understanding of IHC biomarker panels that are suitable for diagnostic, prognostic and predictive testing, and (2) understanding of IHC quality assurance (QA), which makes sure that the tests in these panels work as they should. The two aspects are closely linked together and call for collaborative approach between pathologists and IHC laboratory technologists as both need to be involved in developing and maintaining IHC biomarkers that are "fit-for-purpose"...

Osteoporosis is a systemic skeletal disease involving reduced bone mass and structural deterioration of bone tissue. The use of dual-energy x-ray absorptiometry (DXA) for evaluating bone mass in geriatric patients is well established. However, radiologic technologists also might conduct DXA examinations on younger adults and children. This article discusses diagnosis of osteoporosis and alternative indications for clinical use of DXA.

Earthquakes are a devastating phenomena of nature, causing significant destruction and extensive damage. Most earthquake-related injuries result from collapsing buildings, flying debris, and falling objects. Medical imaging modalities, in particular digital radiography, computed tomography, and sonography, are used to help manage and treat patients injured during an earthquake. Therefore, health care providers, including radiologic technologists, must be aware of the imaging considerations associated with earthquake-related injuries...
