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...

PURPOSE: The aim of this study was to evaluate the association between vertebral endplate morphology and the degree of lumbar intervertebral disc degeneration via magnetic resonance imaging (MRI). METHODS: In total, 150 patients who met the inclusion criteria and were 20-60 years of age were retrospectively evaluated. Patients were evaluated for the presence of intervertebral disc degeneration or herniation, and the degree of degeneration was assessed at all lumbar levels...

PURPOSE: The study sought to determine if the Quality Initiative Program (QUIP) has become part of the radiology culture at our institution. METHODS: After Research Ethics approval, QUIPs from January 2009 to December 2014 were assessed. We evaluated the response rates of radiologists receiving QUIPs to ensure they reviewed them. We performed a survey of radiologists and trainees to gain feedback regarding their perception of QUIPs in February 2014 and in June 2015...

PURPOSE: The study sought to assess the feasibility of performing adult abdominal examinations using a telerobotic ultrasound system in which radiologists or sonographers can control fine movements of a transducer and all ultrasound settings from a remote location. METHODS: Eighteen patients prospectively underwent a conventional sonography examination (using EPIQ 5 [Philips] or LOGIQ E9 [GE Healthcare]) followed by a telerobotic sonography examination (using the MELODY System [AdEchoTech] and SonixTablet [BK Ultrasound]) according to a standardized abdominal imaging protocol...

REVIEW

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...

REVIEW
Jai Shankar, Jillian Banfield
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...

REVIEW
Elizabeth H Y Du, Jai J S Shankar
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...

BACKGROUND AND AIMS: Laparotomy can detect bowel and mesenteric injuries in 1.2%-5% of patients following blunt abdominal trauma. Delayed diagnosis in such cases is strongly related to increased risk of ongoing sepsis, with subsequent higher morbidity and mortality. Computed tomography (CT) scanning is the gold standard in the evaluation of blunt abdominal trauma, being accurate in the diagnosis of bowel and mesenteric injuries in case of hemodynamically stable trauma patients. Aims of the present study are to 1) review the correlation between CT signs and intraoperative findings in case of bowel and mesenteric injuries following blunt abdominal trauma, analysing the correlation between radiological features and intraoperative findings from our experience on 25 trauma patients with small bowel and mesenteric injuries (SBMI); 2) identify the diagnostic specificity of those signs found at CT with practical considerations on the following clinical management; and 3) distinguish the bowel and mesenteric injuries requiring immediate surgical intervention from those amenable to initial nonoperative management...

PURPOSE: Increasing demand has led to questions regarding the appropriateness of advanced imaging exams, particularly for magnetic resonance imaging (MRI). The study aimed to explore variability in MRI service provision and request variation within Canadian academic medical imaging departments, particularly factors potentially affecting appropriate MRI service provision. METHODS: All Canadian academic centres with medical imaging residency programs were invited to participate...

PURPOSE: The study sought to assess the frequency and prognostic value of hyperattenuating adrenal glands on contrast-enhanced computed tomography (CT) scans of surgical intensive care unit (ICU) patients with acute clinical deterioration. METHODS: Eighty-eight consecutive ICU patients (63.2 ± 14.5 years of age) were included in this retrospective analysis. All patients underwent biphasic contrast-enhanced CT due to an acute clinical deterioration. Hyperattenuation of the adrenal glands was assessed subjectively and objectively...

Pablo Caro-Domínguez, Juan Bass, Julie Hurteau-Miller
In 1981, Currarino et al described a triad of findings that consist of partial sacral dysgenesis, presacral mass (anterior meningocele, enteric cyst, or presacral teratoma) and anorectal malformation. Currarino syndrome exhibits variable expressivity and the clinical presentation tends to vary with the age of the subject such as spinal anomaly detected in the fetus, imperforate anus in the newborn, and intractable constipation or neurologic symptoms in the infant and older child. At any age, meningitis can be the presenting symptom and imaging is required for proper investigation...

REVIEW
Anirudh Mirakhur, Justin P McWilliams
Prostate artery embolization has garnered much attention as a promising treatment for lower urinary tract symptoms secondary to benign prostatic hyperplasia. We aim to provide an up-to-date review of this minimally invasive technique, including discussion of potential benefits and technical challenges. Current evidence suggests it is a safe and effective option for patients with medication-refractory urinary obstructive symptoms who are poor surgical candidates or refuse surgical therapy. Larger, randomized studies with long-term follow-up data are needed for this technique to be formally established in the treatment paradigm for benign prostatic hyperplasia...
