Objectives Management of asymptomatic pancreatic cysts is challenging. Guidelines by the American Gastroenterological Association (AGA) and International Association of Pancreatology (Fukuoka) seek to identify high-risk patients. We assessed performance of these guidelines in selecting patients for endoscopic ultrasound (EUS) and/or surgery. Methods PART I - We retrospectively studied 143 asymptomatic cysts with magnetic resonance imaging (MRI) followed by EUS. Appropriate selection for EUS was defined as: malignant cytology or surgical pathology, or development of concerning features on MRI as defined by the guidelines...

BACKGROUND: Bilateral breast magnetic resonance imaging (MRI) is commonly used in the diagnostic workup of breast cancer (BC) to assess extent of disease and identify occult foci of disease. However, evidence for routine use of pre-operative MRI is lacking. Breast MRI is costly and can lead to unnecessary tests and treatment delays. Clinical care pathways (care paths) are value-based guidelines, which define management recommendations derived by expert consensus and available evidence based data...

PURPOSE: Herding is a phenomenon by which individuals follow the behavior of others rather than deciding independently on the basis of their own private information. A herding-like phenomenon can occur in multiple sclerosis (MS) when a neurologist follows a therapeutic recommendation by a colleague even though it is not supported by best practice clinical guidelines. Limited information is currently available on the role of herding in medical care. The objective of this study was to determine the prevalence (and its associated factors) of herding in the management of MS...

INTRODUCTION: Pulmonary hypertension (PH) is a potentially life-threatening condition characterised by elevated pulmonary artery pressure. Early stage PH patients are often asymptomatic. Disease progression is associated with impairment of right ventricular function and progressive dyspnoea. Current guidelines recommend exercise training (grade IIa, level B). However, many questions remain regarding the mechanisms of improvement, intensity of supervision and optimal frequency, duration and intensity of exercise...

While arteriovenous malformations (AVMs) are a common congenital or post-traumatic abnormality, male genital AVMs are rare and have been described in the scrotum or penis in pediatric patients.1,2 We describe a 34-year-old male presenting with recurrent spontaneous penile urethral bleeding found to have an AVM of the penile urethra. While angiography has traditionally been helpful, magnetic resonance imaging (MRI) can aid in the diagnosis and characterization of these lesions.3 Each case of male genital AVM provides a unique challenge to manage depending on the presenting complaint, as there are no guidelines to direct treatment...

BACKGROUND: Prostate cancer (PCa) is the second leading cause of cancer-related mortality and the most frequently diagnosed male malignant disease among men in the Nordic countries. The manifestation of PCa ranges from indolent to highly aggressive disease and due to this high variation in PCa progression, the diagnosis and subsequent treatment planning can be challenging. The current diagnostic approach with PSA testing and digital rectal examination followed by transrectal ultrasound biopsies (TRUS-bx) lack in both sensitivity and specificity in PCa detection and offers limited information about the aggressiveness and stage of the cancer...

: 109 Background: Disease Pathway Management (DPM) is used by Cancer Care Ontario (CCO) to set priorities for cancer control, plan cancer services, and improve the quality of care in Ontario by promoting standardization. The DPM approach applies a framework to examine the performance of the entire system from prevention to end of life care, and to identify any gaps within the system. In 2014, DPM began its breast cancer pathway initiative by mapping the patient journey, depicting evidence-based best practice along the breast cancer care continuum, identifying where further guidance is needed for clinical decision making, and identifying gaps in quality of care and performance measurement indicators...

High-grade glioma is the most aggressive and severe brain tumor that leads to death of almost 50% patients in 1-2 years. Thus, accurate prognosis for glioma patients would provide essential guidelines for their treatment planning. Conventional survival prediction generally utilizes clinical information and limited handcrafted features from magnetic resonance images (MRI), which is often time consuming, laborious and subjective. In this paper, we propose using deep learning frameworks to automatically extract features from multi-modal preoperative brain images (i...

Neuroimaging is commonly utilized in the evaluation of post-cardiac arrest patients, providing a unique ability to visualize and quantify structural brain injury that can complement clinical and electrophysiologic data. Despite its lack of validation, we would advocate that neuroimaging is a valuable prognostication tool, worthy of further study, and an essential part of the armamentarium when used in combination with other modalities in the assessment of the post-cardiac arrest patient. Herein, we discuss the data and its limitations for neuroimaging to date and how it is being studied prospectively...

A decade of research and development in resting-state functional MRI (RSfMRI) has opened new translational and clinical research frontiers. This review aims to bridge between technical and clinical researchers who seek reliable neuroimaging biomarkers for studying drug interactions with the brain. About 85 pharma-RSfMRI studies using BOLD signal (75% of all) or arterial spin labeling (ASL) were surveyed to investigate the acute effects of psychoactive drugs. Experimental designs and objectives include drug fingerprinting dose-response evaluation, biomarker validation and calibration, and translational studies...

While the guidelines for breast cancer screening in average-risk women are well established, screening in high-risk women is not as clear. For women with BRCA1 or BRCA2 mutations, current guidelines recommend screening by clinical breast examination and mammography starting at age 30. For certain high-risk women, additional screening with magnetic resonance imaging (MRI) is encouraged. This review focuses on differentiating imaging modalities used for screening women at high-risk for breast cancer over the age of 50 by discussing the different imaging techniques, cost versus benefit, detection rates, and impact on survival...

BACKGROUND: The National Comprehensive Cancer Network guidelines recommend axillary imaging prior to neoadjuvant chemotherapy (NAC) in breast cancer patients who are clinically node negative (cN0) by physical examination. However, the benefit of this approach remains uncertain. The purpose of this study was to determine whether abnormal axillary imaging pre-NAC predicts nodal metastases post-NAC (ypN+) in cN0 patients. METHODS: cN0 patients undergoing NAC followed by axillary surgery were identified...
