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...

The pterygopalatine fossa is an important anatomic crossroads that is connected with numerous intra- and extracranial spaces via foramina and fissures. Although this fossa is small, its central location in the skull base and its communications provide clinical, radiological, and anatomical significance. In this pictorial review, we aimed to describe the radiologic anatomy of the pterygopalatine fossa, as well as to give some pathologic examples to better understand this major conduit.

PURPOSE: The study sought to assess and compare the prevalence of narrowing of the major extracranial veins in subjects with multiple sclerosis and controls, and to assess the sensitivity and specificity of magnetic resonance venography (MRV) for describing extracranial venous narrowing as it applies to the chronic cerebrospinal venous insufficiency theory, using catheter venography (CV) as the gold standard. METHODS: The jugular and azygos veins were assessed with time-of-flight MRV in this assessor-blinded, case-control study of subjects with multiple sclerosis, their unaffected siblings, and unrelated controls...

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...

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...

RATIONALE AND OBJECTIVES: Preservation of patient privacy and dignity are basic requirements for all patients visiting a hospital. The purpose of this study was to perform an audit of patients' satisfaction with privacy whilst in the Department of Medical Imaging (MI) at the Civic Campus of the Ottawa Hospital. MATERIALS AND METHODS: Outpatients who underwent magnetic resonance imaging (MRI), computed tomography (CT), ultrasonography (US), and plain film (XR) examinations were provided with a survey on patient privacy...

PURPOSE: The study sought to assess how academic interventional radiologists determine and disclose to patients the intraprocedural role of radiology residents in the interventional radiology (IR) suite. METHODS: A qualitative study consisting of in-person interviews with 9 academic interventional radiologists from 3 hospitals was conducted. Interviews were transcribed, and underwent modified thematic analysis. RESULTS: Seven themes emerged...

PURPOSE: The study sought to evaluate the potential of diffusion-weighted magnetic resonance imaging to detect changes in liver diffusion in benign and malignant distal bile duct obstruction and to investigate the effect of the choice of b-values on apparent diffusion coefficient (ADC). METHODS: Diffusion-weighted imaging was acquired with b-values of 200, 600, 800, and 1000 s/mm(2). ADC values were obtained in 4 segments of the liver. The mean ADC values of 16 patients with malignant distal bile duct obstruction, 14 patients with benign distal bile duct obstruction, and a control group of 16 healthy patients were compared...

Peritoneal malignancies are a rare occurrence in children, often metastatic and rarely originating primarily in the peritoneum. The imaging findings of these entities in the pediatric age have not been recently reviewed or they have been previously described or depicted mostly as part of articles discussing each entity separately. This is a review of the most relevant peritoneal malignancies in childhood emphasizing imaging features. Knowledge of these appearances may facilitate diagnosis and staging of these neoplasms...

OBJECTIVES: Per the Breast Imaging Reporting and Data System (BI-RADS) manual, a lesion designated as BI-RADS 3 should have less than a 2% chance of becoming malignancy. With this study, we evaluated the outcome of patients given a BI-RADS 3 designation in the community hospital. Specifically, whether our cancer detection rate for BI-RADS 3 lesions was less than 2% and comparable to rates obtained at other institutions. METHODS: The records of 1037 patients given a BI-RADS 3 on screening mammogram were reviewed over a 1-year period between May 2007 and May 2008...

Chee Hwee Lee, Chih Feng Tan, Okwha Kim, Kyung Jin Suh, Min-Szu Yao, Wing P Chan, Jim S Wu
One of the most common knee injuries is ligament tear, which may initially manifest as an osseous injury in radiographs. Radiologists should therefore be able to recognize ligament tears of the knee as osseous abnormalities in images. This review focuses on the imaging features of knee ligament injuries and their related osseous injuries: anterior cruciate ligament (ACL) tear with Segond fracture; associated marrow contusion; ACL avulsion fracture; posterior cruciate ligament (PCL) tear with osseous avulsion of the ligament including arcuate sign; reverse Segond fracture; PCL avulsion fracture; medial collateral ligament tear with Pellegrini-Stieda disease; lateral collateral ligament tear with avulsion fracture of the fibular head; and patellar ligament injuries with Osgood-Schlatter and Sinding-Larsen-Johansson...

PURPOSE: The study sought to compare performance indicators of computed radiography (CR) using different plate readers, digital direct radiography (DR), and screen-film mammography (SFM) in a population-based screening program. METHODS: This analysis involved women 50-69 years of age who participated in the breast screening program of Quebec (Canada) and who had screening mammogram between January 1, 2007, and September 30, 2012. The detection rate, recall rate, and positive predictive value of CR (n = 672,125 mammograms) and DR (n = 60,023) were compared to SFM (n = 782,894) using mixed-effect logistic regression, adjusting for potential confounders...

The radiology report is the culmination of image acquisition, meticulous interpretation, and the generation of deliberate and thoughtful recommendations. It is essentially a translation of images into words, and as such must convey as much pertinent detail needed by the clinician in as concise a format as possible. Several important factors affect the overall quality of the finished report. Active voice helps to convey information more confidently, and in a manner that is easier to read and understand. The use of several words and phrases is frowned upon, as it makes the radiologist sound uncertain...
