Major issues in the implementation of screening for lung cancer by means low-dose computed tomography (CT) are definition a positive result and management nodules detected on scans. We conducted population-based prospective study to determine factors predicting probability that first CT scans malignant or will be found follow-up.We analyzed data from two cohorts participants undergoing screening. The development set included Pan-Canadian Early Detection Lung Cancer Study (PanCan). validation...
IntroductionLung cancer risk prediction models have the potential to make programs more affordable; however, economic evidence is limited.MethodsParticipants in National Lung Cancer Screening Trial (NLST) were retrospectively identified with tool developed from Prostate, Lung, Colorectal and Ovarian Trial. The high-risk subgroup was assessed for lung incidence demographic characteristics compared those low-risk Pan-Canadian Early Detection of Study (PanCan), which an observational study that...
BackgroundCurrent lung cancer screening guidelines use either mean diameter, volume, or density of the largest nodule on previous CT scan appearance a new to ascertain timing next scan. We aimed develop an accurate protocol by estimating 3-year risk after two scans using deep learning radiologists' readings and other universally available clinical information.MethodsA algorithm (referred as DeepLR) was developed data from participants who had received at least up 2 years apart in National...
On March 11, 2020, the World Health Organization declared infection related to a novel coronavirus (SARS-CoV-2) pandemic. The role and impact of imaging predates this declaration continues change rapidly. This article is consensus statement provided by Canadian Society Thoracic Radiology Association Radiologists outlining in COVID-19 patients. objectives are answer key questions chest provide guidance for radiologists who interpreting such studies during radiography (CXR), computed...
It is estimated that millions of North Americans would qualify for lung cancer screening and billions dollars national health expenditures be required to support population-based computed tomography programs. The decision implement such programs should informed by data on resource utilization costs.Resource were collected prospectively from 2059 participants in the Pan-Canadian Early Detection Lung Cancer Study using low-dose (LDCT). Participants who had 2% or greater risk over 3 years a...
The purpose of this study is to establish provincial diagnostic reference levels (DRLs) and determine whether process may help reduce the patient radiation dose from most frequently performed CT examinations.We investigated following examinations: head, chest, low-dose abdomen pelvis, abdomen, pelvis examinations. sample for each protocol included 15 patients average body weight (mean [± SD], 70 ± 20 kg). differences in between scanners were evaluated using one-way ANOVA. Correlations dose,...
Plasma pro-surfactant protein B (pro-SFTPB) levels have recently been shown to predict the development of lung cancer in current and ex-smokers, but ability pro-SFTPB measures chronic obstructive pulmonary disease (COPD) severity is unknown. We evaluated performance characteristics as a biomarker function decline population ex-smokers. were measured 2503 ex-smokers enrolled Pan-Canadian Early Detection Lung Cancer Study. Linear regression was performed determine relationship changes forced...
Background and Objective: Incidental pulmonary nodules (IPNs) are common increasingly detected with the overall rise of radiologic imaging. Effective IPN management is necessary to ensure lung cancer not missed. This study aims describe current landscape in Canada, understand barriers optimal management, identify opportunities for improvement. Methods: We performed a narrative literature review by searching biomedical electronic databases relevant articles published between January 1, 2010,...
We evaluated the reliability of various multidetector computed tomography (MDCT) parameters for diagnosis and severity assessment pulmonary hypertension (PH) with consideration World Health Organization (WHO) classification.A total 172 patients were included in this retrospective study. One hundred fourteen had a PH (mean artery pressure ≥25 mm Hg), 58 without <20 Hg) served as control subjects. The grouped according to WHO classification based on etiology.The significantly greater main,...
There is a need to expand eligibility criteria for lung cancer screening beyond age and smoking history. In this study, we sought assess whether light-or-never-smokers heavy smokers differ in molecular immunologic markers based on conventional criteria.
Abstract RATIONALE: Appropriate management of low-dose computed tomography (LDCT) screening detected lung nodules will have significant implications for health care resource utilization and minimizing harm from radiation exposure related to imaging studies, invasive procedures clinically distress. OBJECTIVES We aimed to: provide a practical, evidence-based best practice framework healthcare professionals (HP) manage LDCT identify areas that require future studies. METHODS The Canadian...
The investigation of acute pulmonary embolism is a common task for radiologists in Canada. Technical image quality and reporting must be excellent; life-threatening disease that should not missed but overdiagnosis unnecessary treatment avoided. most frequently performed imaging investigation, computed tomography angiogram (CTPA), can limited by poor arterial opacification, technical artifacts interpretative errors. Image affected patient factors (such as body habitus, motion artifact cardiac...
Acute pulmonary embolism (APE) is a well-recognized cause of circulatory system compromise and even demise which can frequently present diagnostic challenge for the physician. The primarily due to frequency indeterminate presentations as well several other conditions have similar clinical presentation. This often obliges physician establish firm diagnosis potentially serious outcomes related this disease. Computed tomography angiography (CTPA) has increasingly cemented its role primary...
Guidelines aimed at improving care for lung cancer, the leading cause of cancer-related death in Canada and worldwide, require accurate knowledge diagnostic setting or pathway. We sought to determine how often cancer is initially diagnosed through emergency department.We performed a descriptive study that included all cases primary residents Nova Scotia 2014. Cancer registry data date Aug. 31, 2016. reviewed linked hospital records, including laboratory imaging results, identify first...
