Cardiac anatomy can be challenging to grasp because of its complex three-dimensional nature and remains one the most topics teach. In light some exciting technological advances in field virtual reality (VR), we sought test viability assess efficacy this computer-generated model for purposes teaching cardiac anatomy. Before learning anatomy, first-year undergraduate medical students participated an anatomically correct VR simulation heart. Students were randomly distributed into control...
BackgroundEngland and Wales have one of the highest frequencies autopsy in world. Implementation post-mortem CT (PMCT), enhanced with targeted coronary angiography (PMCTA), adults to avoid invasive would cultural, religious, potential economic benefits. We aimed assess diagnostic accuracy PMCTA as a first-line technique investigations.MethodsIn this single-centre (Leicester, UK), prospective, controlled study, we selected cases natural non-suspicious unnatural death referred Her Majesty's...
There is a paucity of studies comparing asthma and chronic obstructive pulmonary disease (COPD) based on thoracic quantitative computed tomographic (QCT) parameters.We sought to compare QCT parameters airway remodeling, air trapping, emphysema between asthmatic patients with COPD explore their relationship airflow limitation.Asthmatic (n = 171), 81), healthy subjects 49) recruited from single center underwent clinical characterization.Proximal percentage wall area (%WA) was significantly...
Background There are limited data on the incremental value of parametric mapping compared with core cardiac MRI protocols for suspected cardiomyopathy in routine clinical practice. Purpose To evaluate impact T1 and T2 practice respect to diagnostic accuracy, reader confidence, downstream imaging utilization. Materials Methods In this retrospective single-center study, consecutive scans obtained without evaluation between January 2017 October 2019 were evaluated. Diagnostic accuracy...
CT calcium scoring (CTCS) and cardiac angiography (CTCA) are widely used in patients with stable chest pain to exclude significant coronary artery disease (CAD). We aimed resolve uncertainty about the prevalence of obstructive long-term outcomes a zero-calcium score (ZCS).Consecutive symptoms referred for CTCS or CTCA from clinics tertiary cardiothoracic centre were prospectively enrolled. In those ZCS, CAD on was determined. A follow-up all-cause mortality obtained NHS tracer service. total...
Background CT-guided microcoil localization has been shown to reduce the need for thoracotomy or video-assisted thoracoscopic surgery (VATS) anatomic resection. However, only short-term follow-up after and lung resection previously reported. Purpose To assess diagnostic utility recurrence-free survival over a minimum of 2 years following VATS. Materials Methods Among 1950 VATS procedures performed in single tertiary institution from October 2008 through April 2016, 124 consecutive patients...
The use of post-mortem imaging is expanding throughout the world with increasing advanced techniques, such as contrast-enhanced CT and MRI. questions asked are complex can be very different, for example natural sudden death investigation will focus on cause, whereas trauma cause often clear, but injury patterns may revealing in investigating background to incident. Post-mortem different clinical regarding both appearance pathology information required, there much learn from many years...
The coronavirus disease 2019 (COVID-19) pandemic has led to widespread changes in all health care settings including academic radiology departments. purpose of this survey-based study was investigate the impact COVID-19 on resident training and education workflow Canada terms nature, scale, heterogeneity changes, preparedness adaptation, perceptions present future training.A 30-question web-based survey sent 17 residency program directors across Canada. A separate 32-question 460 residents...
Chronic lung allograft dysfunction (CLAD) limits long-term survival after transplantation (LTx). Early detection or prediction of CLAD can lead to changes in patient management that, turn, may improve prognosis. The purpose this study was investigate the utility quantitative computed tomography (CT) density analysis early CLAD.This retrospective cohort drawn from all consecutive adult, first LTxs performed between 2006 and 2011. Post-transplant monitoring included scheduled surveillance...
PURPOSE Lung cancer screening programs generate a high volume of low-dose computed tomography (LDCT) reports that contain valuable information, typically in free-text format. High-performance named-entity recognition (NER) models can extract relevant information from these automatically for inter-radiologist quality control. METHODS Using LDCT report data longitudinal lung program (8,305 reports; 3,124 participants; 2006-2019), we trained rule-based model and two bidirectional long...
Purpose: To evaluate the diagnostic utility of Look Locker inversion time (TI) sequence on cardiac magnetic resonance imaging in patients with suspected amyloidosis and to whether there are differences nulling pattern between amyloid types. Materials Methods: A total 144 who had undergone were included this retrospective study. Sixty-four (62.1±9.2 y, 70.3% male, 68.8% light chain [AL], 18.8% familial transthyretin caused by mutant genes [ATTRm], 12.5% wild-type [ATTRwt]) 80 did not have...
Abstract The aim of this study was to compare whole lung CT density histograms predict critical illness outcome and hospital length stay in a cohort 80 COVID-19 patients. chest images on segmented lungs were retrospectively analyzed. Functional Principal Component Analysis (FPCA) used find the main modes variations histograms. features, severity score, COVID-GRAM score patient clinical data assessed for predicting using logistic regression models survival analysis. ROC analysis predictors...
