Tomosynthesis-Directed Coaxial Core Biopsy of Tomosynthesis-Detected Architectural Distortion: Indications and Logistics
As digital breast tomosynthesis has become more widely integrated into clinical practice for both screening and diagnostic evaluation, the need to biopsy suspicious findings only visible on tomosynthesis has increased. Based on multiple reports, the most frequent imaging feature that presents in this way is architectural distortion, which carries a 21%-36% chance of malignancy [1 –3]. Several centres have reported on the accuracy of tomosynthesis-directed needle localization and vacuum assisted biopsy for obtaining a diagnosis for these lesions [4–6].

Gender Identity and Bone Densitometry
An adult transgendered person was referred for dual energy x-ray absorptiometry (DXA). At the time there was no guidance for technologists faced with entering either the patient's birth sex or transgender sex into the instrument's database. Technologists have indicated a need for direction on this practical matter. (Source: Canadian Association of Radiologists Journal)

Can Apparent Diffusion Coefficient Predict the Clinical Outcome in  Drowned Children?
Pediatric cerebral hypoxic-ischemic injury frequently results in severe neurological outcome. Imaging with diffusion-weighted magnetic resonance imaging (DWi) demonstrates that the acute cerebral injury and apparent diffusion coefficient (ADC) allow the assessment of the severity of brain damage. The main objective was to examine if spatial distribution of reductions in ADC values is associated with clinical outcome in drowned children. (Source: Canadian Association of Radiologists Journal)

Central Nervous System Tuberculosis: An Imaging Perspective
The increasing prevalence of tuberculosis in both immunocompetent and immunocompromised individuals in recent years makes the disease a topic of universal concern. It has insidious onset and can affect virtually any organ system in the body, including the central nervous system (CNS). CNS tuberculosis (TB) is becoming more and more complex and atypical with onset of multidrug-resistant TB. Routine diagnostic techniques using serology and body tissue are time consuming and may delay the definitive management. (Source: Canadian Association of Radiologists Journal)

Guidelines for Use of Computed Tomography Angiogram as an Ancillary Test for Diagnosis of Suspected Brain Death
Neurological determination of death (NDD) or brain death is primarily a clinical diagnosis. Ancillary testing is used in situations where clinical criteria of brain death cannot be completed fully and is used to support the clinical diagnosis. Global absence of cerebral blood flow by catheter angiography or nuclear medicine perfusion (Tc99) is the recommended gold standard for confirmation by ancillary testing. Computed tomography angiography (CTA) is a recommended ancillary test in Ontario for evaluation of absence of intracranial flow [1]. (Source: Canadian Association of Radiologists Journal)

Diffusion-Weighted Imaging of the Brain: Beyond Stroke
Diffusion-weighted imaging provides image contrast that is different from that provided by conventional magnetic resonance imaging techniques. It is highly sensitive for detection of cytotoxic oedema, and as such has gained favor in the detection of acute infarcts. However, diffusion-weighted imaging is underrepresented in the characterisation of many other disease processes. Our objective is to differentiate diseases that manifest with various neurological disorders, based on diffusion contrast and apparent diffusion coefficient values and review of hyper- and hypointense lesions on diffusion-weighted imaging.

Posterior Reversible Encephalopathy Syndrome: A Review
Radiologists may be the first to suggest the diagnosis of posterior reversible encephalopathy syndrome (PRES). PRES is associated with many diverse clinical entities, the most common of which are eclampsia, hypertension, and immunosuppressive treatment. Radiologists should be aware of the spectrum of imaging findings in PRES. When promptly recognized and treated, the symptoms and radiological abnormalities can be completely reversed. When unrecognized, patients can progress to ischemia, massive infarction, and death. (Source: Canadian Association of Radiologists Journal)

Rapid Endovascular Treatment of Acute Ischemic Stroke: What a General Radiologist Should Know
Stroke is the second leading cause of mortality and the third leading cause of disability-adjusted life-years worldwide. For each minute of an ischemic stroke, an estimated 1.9 million brain cells die. The year 2015 saw the unprecedented publication of 5 multicentre, randomized, controlled trials. These studies showed that patients with acute ischemic stroke caused by large-vessel thrombus occlusion of the proximal anterior circulation had significantly reduced disability at 90  days when treated with endovascular thrombectomy and usual stroke care compared to usual stroke care alone.
