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...

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...

Medical staffs like radiological technologists, doctors, and nurses are at an increased risk of exposure to radiation while assisting the patient in a position or monitor contrast medium injection during computed tomography (CT). However, methods to protect medical staff from radiation exposure and protocols for using radiological protection equipment have not been standardized and differ among hospitals. In this study, the distribution of scattered X-rays in a CT room was measured by placing electronic personal dosimeters in locations where medical staff stands beside the CT scanner gantry while assisting the patient and the exposure dose was measured...

ST-elevation myocardial infarction (STEMI) is a fatal condition. Prompt primary percutaneous coronary intervention is associated with lower mortality. However, community hospitals in Japan lack human and medical resources, and implementation of the same strategies as those used in the USA, such as an on-call cardiologist at the hospital, to achieve a door-to-balloon time of ≤ 90 min appears particularly challenging. Therefore, we used Training for Effective and Efficient Action in Medical Service-Better Process (TEAMS-BP) to develop a new process and assessed its effectiveness in reducing door-to-balloon time...

Positioning of an intraoperative C-arm to achieve clear visualization of a particular anatomical feature often involves repeated fluoroscopic views, which cost time and radiation exposure to both the patient and surgical staff. A system for virtual fluoroscopy (called FluoroSim) that could dramatically reduce time- and dose-spent "fluoro-hunting" by leveraging preoperative computed tomography (CT), encoded readout of C-arm gantry position, and automatic 3D-2D image registration has been developed...

We created the device, which can conduct a radiological technologist's voice to a subject during CT scanning. For 149 lung cancer, dynamic respiratory CT were performed. 92 cases were performed using this device, the others were without this device. The respiratory cycle and respiratory amplitude were analyzed from the lung density. A stable respirating cycle was obtained by using the audio indicator system. The audio indicator system is useful for respiratory dynamic CT.

Many facets of an image acquisition workflow leave a digital footprint, making workflow analysis amenable to an informatics-based solution. This paper describes a detailed framework for analyzing workflow and uses acute stroke response timeliness in CT as a practical demonstration. We review methods for accessing the digital footprints resulting from common technologist/device interactions. This overview lays a foundation for obtaining data for workflow analysis. We demonstrate the method by analyzing CT imaging efficiency in the setting of acute stroke...
