Management of Breast Magnetic Resonance Imaging-Detected Lesions
Canadian Association of Radiologists Journal - Tập 63 - Trang 192-206 - 2012
Jean M. Seely
Breast magnetic resonance imaging (MRI) has become an essential component of breast imaging. Whether it is used as a problem-solving tool or a screening test or for staging patients with breast cancer, it detects many lesions in the breast. The challenge for the radiologist is to distinguish significant from insignificant lesions and to direct their management. A brief summary of the terminology a... hiện toàn bộ

Imaging Manifestations of Acute and Chronic Renal Infection That Mimics Malignancy: How to Make the Diagnosis Using Computed Tomography and Magnetic Resonance Imaging
Canadian Association of Radiologists Journal - Tập 70 - Trang 424-433 - 2019
Amar Udare, Jorge Abreu-Gomez, Satheesh Krishna, Matthew McInnes, Evan Siegelman, Nicola Schieda
Purpose To review the computed tomography and magnetic resonance imaging manifestations of acute and chronic renal infections that may mimic malignancy and to provide useful tips to establish an imaging diagnosis. Conclusion Acute and chronic bacterial pyelonephritis are usually readily diagnosed clinically and on imaging when the diagnosis is suspected based upon clinical presentation. When unsus... hiện toàn bộ
Superolateral Hoffa's Fat Pad Edema and Trochlear Sulcal Angle Are Associated with Isolated Medial Patellofemoral Compartment Osteoarthritis
Canadian Association of Radiologists Journal - Tập 69 - Trang 450-457 - 2018
Sara Weintraub, Ronnie Sebro
PurposeTo evaluate whether mediopatellar plica and knee morphometric measurements obtained from magnetic resonance imaging (MRI) studies are associated with isolated medial patellofemoral osteoarthritis in young adults.MethodsMRI studies from 60 patients with isolated medial patellofemoral osteoarthritis and 90 control patients with normal knee MRI studies were reviewed. The presence of mediopatel... hiện toàn bộ
The Efficacy of Computed Tomography-Guided Percutaneous Spine Biopsies in Determining a Causative Organism in Cases of Suspected Infection: A Systematic Review
Canadian Association of Radiologists Journal - Tập 70 - Trang 96-103 - 2019
Madeleine Sertic, Leighanne Parkes, Sabrina Mattiassi, Kenneth Pritzker, Michael Gardam, Kieran Murphy
Purpose In suspected spondylodiscitis and vertebral osteomyelitis, computed tomography (CT)-guided biopsies are often performed to determine a causative organism and guide antimicrobial therapy. The aim of this study is to determine the diagnostic culture yield of CT-guided biopsies performed in cases of suspected spinal infections. Methods A literature search of PubMed and MEDLINE up to April 201... hiện toàn bộ
Gadolinium-Based Contrast Agents in Kidney Disease: Comprehensive Review and Clinical Practice Guideline Issued by the Canadian Association of Radiologists
Canadian Association of Radiologists Journal - Tập 69 - Trang 136-150 - 2018
Nicola Schieda, Jason I. Blaichman, Andreu F. Costa, Rafael Glikstein, Casey Hurrell, Matthew James, Pejman Jabehdar Maralani, Wael Shabana, An Tang, Anne Tsampalieros, Christian van der Pol, Swapnil Hiremath
Use of gadolinium-based contrast agents (GBCAs) in renal impairment is controversial, with physician and patient apprehension in acute kidney injury (AKI), chronic kidney disease (CKD), and dialysis because of concerns regarding nephrogenic systemic fibrosis (NSF). The position that GBCAs are absolutely contraindicated in AKI, CKD stage 4 or 5 (estimated glomerular filtration rate [eGFR] <30 mL/mi... hiện toàn bộ
How Well Are We Respecting Patient Privacy in Medical Imaging? Lessons Learnt from a Departmental Audit
Canadian Association of Radiologists Journal - Tập 67 - Trang 339-344 - 2016
Marc Dilauro, Rebecca Thornhill, Najla Fasih
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), comput... hiện toàn bộ
The Relationship of Body Mass Index and Abdominal Fat on the Radiation Dose Received during Routine Computed Tomographic Imaging of the Abdomen and Pelvis
Canadian Association of Radiologists Journal - Tập 63 - Trang 260-266 - 2012
Victoria O. Chan, Shaunagh McDermott, Orla Buckley, Sonya Allen, Michael Casey, Risteard O’Laoide, William C. Torreggiani
Purpose To determine the relationship of increasing body mass index (BMI) and abdominal fat on the effective dose acquired from computed tomography (CT) abdomen and pelvis scans. Methods Over 6 months, dose-length product and total milliamp-seconds (mAs) from routine CT abdomen and pelvis scans of 100 patients were recorded. The scans were performed on a 64-slice CT scanner by using an automatic e... hiện toàn bộ
Perception of Radiation Exposure and Risk among Patients, Medical Students, and Referring Physicians at a Tertiary Care Community Hospital
Canadian Association of Radiologists Journal - Tập 64 - Trang 208-212 - 2013
Michelle L. Ricketts, Mark O. Baerlocher, Murray R. Asch, Andy Myers
Background It is important for physicians to be aware of the radiation doses as well as the risks associated with diagnostic imaging procedures that they are ordering. Methods A survey was administered to patients, medical students, and referring physicians from a number of specialties to determine background knowledge regarding radiation exposure and risk associated with commonly ordered medical ... hiện toàn bộ
Comparison of General Anesthesia and Conscious Sedation during Computed Tomography–Guided Radiofrequency Ablation of T1a Renal Cell Carcinoma
Canadian Association of Radiologists Journal - Tập 69 - Trang 24-29 - 2018
Hae Jin Kim, Byung Kwan Park, In Sun Chung
Purpose Percutaneous radiofrequency ablation is so painful that this treatment requires pain control such as conscious sedation or general anesthesia. It is still unclear which type of anesthesia is better for treatment outcomes of renal cell carcinoma. This study aimed to compare general anesthesia and conscious sedation in treating patients with renal cell carcinoma with radiofrequency ablation.... hiện toàn bộ
