Lu Anne V Dinglasan, Mary H Scanlon
The primary goal of any radiology residency program is to train clinically competent radiologists. However, some radiology programs go above and beyond basic ACGME requirements and produce highly productive radiologists who contribute to the field in research, education and technology. At the core of such residencies are the people who comprise it, including self-motivated, personable residents and faculty who can facilitate excellence from their trainees. Indeed, radiology residencies which create unique programs in response to evolving resident interests can help foster resident-driven research, advocacy, technological innovation and early leadership...

AIM: The most ubiquitous chest diagnostic method is the chest radiograph. A common radiographic finding, quite often incidental, is the nodular pulmonary lesion. The detection of small lesions out of complex parenchymal structure is a daily clinical challenge. In this study, we investigate the efficacy of the computer-aided detection (CAD) software package SoftView™ 2.4A for bone suppression and OnGuard™ 5.2 (Riverain Technologies, Miamisburg, OH, USA) for automated detection of pulmonary nodules in chest radiographs...

Although image-based human stereotaxis began with Spiegel and Wycis in 1947, the major principles of radiographic stereotaxis were formulated 50 years earlier by the French scientific photographer Gaston Contremoulins. In 1897, frustrated by the high morbidity of bullet extraction from the brain, the Parisian surgeon Charles Rémy asked Contremoulins to devise a method for bullet localization using the then new technology of x-rays. In doing so, Contremoulins conceived of many of the modern principles of stereotaxis, including the use of a reference frame, radiopaque fiducials for registration, images to locate the target in relation to the frame, phantom devices to locate the target in relation to the fiducial marks, and the use of an adjustable pointer to guide the surgical approach...

The increasing availability of dual-energy computed tomography (DECT) has set the stage for an exciting era in CT technology. This technique is extensively used throughout the world with numerous centres working on the applications of DECT in various radiology subspecialty areas. DECT provides many advantages over the conventional single-energy scan. Instead of a single set of images, radiologists have access to multiple sets of images from a single acquisition. The DECT workstation enables the reader to generate images, according to the clinical setting, in order to answer a specific clinical question...

BACKGROUND: In a preliminary experience, we claimed the potential value of 3D printing technology for pre-operative counseling and surgical planning. However, no objective analysis has ever assessed its additional benefit in transferring anatomical information from radiology to final users. We decided to validate the pre-operative use of 3D-printed anatomical models in patients with solid organs' diseases as a new tool to deliver morphological information. METHODS: Fifteen patients scheduled for laparoscopic splenectomy, nephrectomy, or pancreatectomy were selected and, for each, a full-size 3D virtual anatomical object was reconstructed from a contrast-enhanced MDCT (Multiple Detector Computed Tomography) and then prototyped using a 3D printer...

There has been a resurgence of interest in defining the optimal treatment for severe pulmonary embolism (PE), fueled by pivotal and provocative trials, new catheter-based medical devices, and growing evidence of deleterious short- and long-term outcomes. In this environment, and especially given the multidisciplinary nature of PE care, the interventional radiologist (IR) needs to become an astute, disease-specific expert. This review article describes the following "steps" an IR can take to reach this level: (1) understand PE stratification and epidemiology; (2) recognize the treatment goals for massive PE; (3) recognize the wide range of attitudes toward therapeutic escalation for submassive PE; (4) recognize what we do not know about the treatment of submassive PE and the limitations of current studies; (5) know the literature surrounding inferior vena cava filter insertion for severe PE; (6) integrate into the longitudinal care of the patient; and (7) be at the leading edge of new trials and technologies...

OBJECTIVES: Long-term follow-up care after total joint arthroplasty is essential to evaluate hip and knee arthroplasty outcomes, to provide information to physicians and improve arthroplasty performance, and to improve patients' health condition. In this paper, we aim to improve the communication between arthroplasty patients and physicians and to reduce the cost of follow-up controls based on mobile application technologies and cloud computing. METHODS: We propose a mobile-based healthcare system that provides cost-effective follow-up controls for primary arthroplasty patients through questions about symptoms in the replaced joint, questionnaires (WOMAC and SF-36v2) and the radiological examination of knee or hip joint...

We previously developed an animal model of calcium oxalate (CaOx) deposition on the Malphigian tubules of Drosophila melanogaster as a model of urolithiasis. Here, we introduce a new tool for the study of anatomical structure for Drosophila. As a consequence of technical development, the invention of micro-computerized tomography (CT) has been introduced to the small animal, such as rat and mice. We used Drosophila as a model organism and fed the flies 0.5% lithogenic agent ethylene glycol for 3 weeks. Samples were simply prepared for further scanned by micro-CT to scan samples at 800 nm resolution...

Incidental findings are part of the routine radiological reporting workflow and describe findings which are not primarily the focus of the clinical context or the request of the referring physician. The clinical implications of such incidental findings can be very different, for example simple renal cysts or space-occupying lesions suspected of being tumors. A categorization of clinical findings according to the clinical relevance is therefore recommended. Documentation and communication of clinically relevant incidental findings are a part of the radiological reporting process and essential for reduction of the medicolegal risk...

The primary goal of comparative effectiveness research (CER) is to define the optimal choice among alternative diagnostic and interventional strategies for a given clinical scenario among major stakeholders in the health care system. In an era where health care decision makers are demanding greater evidence of improved patient outcomes from the use of medical technologies, musculoskeletal (MSK) imagers must be more engaged in generating quality CER. We provide an overview of CER and its expanding role in U...

Rapidly rising health care costs coupled with variability in pricing and patient service have led to intense public scrutiny and pressure for health care providers to demonstrate value. Recent changes in legislation and payment models have intensified a shift from volume-based to value-based care, transferring risk from payers to providers. The American College of Radiology's Imaging 3.0 initiative encourages radiologists to become leaders in this changing health care landscape, helping to redefine value relative to health outcomes that matter to patients...

REVIEW
Ruth C Wilkins, Matthew A Rodrigues, Lindsay A Beaton-Green
Biodosimetry methods, including the dicentric chromosome assay, the cytokinesis-block micronucleus assay and the γH2AX marker of DNA damage are used to determine the dose of ionizing radiation. These techniques are particularly useful when physical dosimetry is absent or questioned. While these assays can be very sensitive and specific, the standard methods need to be adapted to increase sample throughput in the case of a large-scale radiological/nuclear event. Recent modifications to the microscope-based assays have resulted in some increased throughput, and a number of biodosimetry networks have been, and continue to be, established and strengthened...
