Congenital Anomalies of the Superior Vena Cava: Embryological Correlation, Imaging Perspectives, and Clinical Relevance
There is a wide spectrum of congenital anomalies of the superior vena cava, which are more increasingly recognized in cross-sectional imaging. Although some of these anomalies are asymptomatic, others have important clinical and interventional implications. Imaging modalities such as computed tomography and magnetic resonance imaging play an important role in the accurate characterization of these anomalies, which is essential for mapping prior to surgeries or interventions. In this article, we review a wide range of anomalies of the superior vena cava, including the embryological basis, cross-sectional imaging findings, a...

Managing Incidentalomas Safely: Do Computed Tomography Requisitions Tell Us What We Need to Know?
Technological advancements and the ever-increasing use of computed tomography (CT) have greatly increased the detection of incidental findings, including tiny pulmonary nodules. The management of many “incidentalomas” is significantly influenced by a patient's history of cancer. The study aim is to determine if CT requisitions include prior history of malignancy.

Canadian Association of Radiologists: Guide on Computed Tomography Screening for Lung Cancer
The past several years have seen the publication of the results of several major studies, evaluating the use of low-dose computed tomography (LDCT) scanning in the screening of high-risk individuals for lung cancer. Many major U.S. organizations have issued guidelines in support of performing lung cancer screening in appropriate populations, and organized screening programs are becoming well established in the United States. In Canada, however, there are currently very few documents outlining screening recommendations. (Source: Canadian Association of Radiologists Journal)

A Pictorial Review of Hepatobiliary Magnetic Resonance Imaging With Hepatocyte-Specific Contrast Agents: Uses, Findings, and Pitfalls of Gadoxetate Disodium and Gadobenate Dimeglumine
Magnetic resonance imaging (MRI) has a well-established role as a highly specific and accurate modality for characterizing benign and malignant focal liver lesions. In particular, contrast-enhanced MRI using hepatocyte-specific contrast agents (HSCAs) improves lesion detection and characterization compared to other imaging modalities and MRI techniques. In this pictorial review, the mechanism of action of gadolinium-based MRI contrast agents, with a focus on HSCAs, is described. The clinical indications, protocols, and emerging uses of the 2 commercially available combined contrast agents available in the United States, ga...

Imaging Intra-abdominal Burkitt's Lymphoma: From Discrete Bowel Wall Thickening to Diffuse Soft Tissue Infiltration
Burkitt's lymphoma is a highly aggressive non-Hodgkin's B-cell lymphoma, which often presents with intra-abdominal involvement. The purpose of this pictorial review is to illustrate the various intra-abdominal imaging findings of Burkitt's lymphoma. Extranodal disease at presentation is common, including involvement of the bowel, stomach, pancreas, spleen, and mesentery. (Source: Canadian Association of Radiologists Journal)

Clinical Decision Support in Computerized Providers' Order Entry for Imaging Tests in Canada
Despite its considerable contributions to patient care, utilization of medical imaging is a cost driver in health care [1]. In diagnostic imaging increasing utilization is related to rapid technological change allowing clinicians to achieve rapid, accurate diagnosis [2]. This rapid expansion has also led to some inappropriate utilization, as referring physicians find it progressively challenging to keep up with complex, new imaging technologies. Physicians' decisions directly and indirectly account for approximately 80% of overall healthcare expenditures [3]. (Source: Canadian Association of Radiologists Journal)

Development of an Undergraduate Radiology Curriculum: Ten-Year Experience From the University of British Columbia
Exposing medical students to the specialty of radiology is essential for recruiting excellent residents and cultivating an early understanding of the value of radiology in clinical practice. Several studies have demonstrated that medical student engagement at the undergraduate level —through teaching, research, and mentorship—plays an important role in determining students' choice of residency [1–4]. However, undergraduate medical curriculum development teams across the country often do not include a radiologist. (Source: Canadian Association of Radiologists Journal)

Radiology Exposure in the Undergraduate Curriculum: A Medical Student Perspective on Quality and Opportunities for Positive Change
This article is a continuation of a qualitative study designed to explore how radiology exposures can impact medical student opinions and perceptions of radiology and radiologists. We focused on: 1) conducting a radiology exposure inventory from the perspective of the medical student; 2) student evaluation of the quality of the radiology exposures and suggestions for positive change; and 3) development of a framework to address the needs of medical students as it relates to radiology education in the undergraduate medical curriculum.

Greening the Radiology Department: Not a Big Mountain to Climb
An environmental-friendly radiology department should be a requirement of the future era. The aim of this article is to make radiologists aware of their responsibilities for a greener world. We have suggested a number of minor but important changes in various sections of a radiology department that can make the radiology department more environmentally friendly. These small steps require relatively little effort on our part but cumulatively, may have a huge positive impact on our environment. (Source: Canadian Association of Radiologists Journal)

Early Radiographic and Tomographic Manifestations of Legionnaires' Disease
Legionnaires' disease (LD) may occur sporadically or in the course of outbreaks, where the typical radiological manifestations of the disease may better be delineated. We took advantage of a rare community-based epidemic of LD (181 patients) that occurred in 2012 in Quebec City, Canada, to describe the radiographic features of LD and compare the its tomographic presentation with that of community-acquired pneumonia caused by common bacteria other than Legionella pneumophila.

Intradiscal O2O3: Rationale, Injection Technique, Short- and Long-term Outcomes for the Treatment of Low Back Pain Due to Disc Herniation
The management of low back pain should always start with a conservative approach; however, when it fails, intervention is required and at that moment the most appropriate choice remains unclear. Before invasive surgery, minimally invasive techniques can be adopted. In European trials and in a trans-Canadian clinical trial 03 ozone has been used successfully. In total over 50,000 patients have been treated safely. Ozone is a gas normally present in the atmosphere with potent oxidizing power; it has been used for percutaneous intradiscal injection combined with oxygen (O2O3) at very low concentrations for 15  years in Europ...

Fungal Rhinosinusitis: A Radiological Review With Intraoperative Correlation
The interaction between fungi and the sinonasal tract results in a range of clinical presentations with a broad spectrum of clinical severity. The most commonly accepted classification system divides fungal rhinosinusitis into invasive and noninvasive subtypes based on histopathological evidence of tissue invasion by fungi. Invasive fungal rhinosinusitis is subdivided into acute invasive and chronic invasive categories. The chronic invasive category includes a subcategory of chronic granulomatous disease.

The Paradigm Shift
Don't underestimate the power of your vision to change the world. Whether that world is your office, your community, an industry or a global movement, you need to have a core belief that what you contribute can fundamentally change the paradigm of way of thinking about problems.Leroy Hood, American biologist (b. 1938) (Source: Canadian Association of Radiologists Journal)
