Several paradigms for evidence-based practice (EBP) exist. One model proposes that specialist academic centers should primarily construct valid guidelines for various topics in medicine (top-down model). An alternative model integrates "the best research evidence with clinical expertise and patient values" (bottom-up model). Whereas the former model(More)
OBJECTIVE The purpose of this study was to investigate whether MRI can quantify the severity and extent of left ventricular noncompaction and detect trabecular delayed hyperenhancement and whether doing so can show a relationship with clinical stage of disease. MATERIALS AND METHODS In a retrospective blinded study, nine patients with left ventricular(More)
OBJECTIVE The purpose of our study was to evaluate the accuracy of cardiac 64-MDCT to quantify the grade of stenosis of nonculprit lesions. SUBJECTS AND METHODS Twenty-nine consecutive patients (23 men and six women; mean age, 62 +/- 10 years) presenting with acute coronary syndrome (ACS) had nonculprit coronary lesions of >or= 30% stenosis quantified on(More)
OBJECTIVE This article reviews the optimal cardiac MRI sequences for and the spectrum of imaging appearances of cardiac tumors. CONCLUSION Recent technologic advances in cardiac MRI have resulted in the rapid acquisition of images of the heart with high spatial and temporal resolution and excellent myocardial tissue characterization. Cardiac MRI provides(More)
OBJECTIVES Advances in computed tomography technology may permit the evaluation of coronary disease, aortic dissection, and pulmonary embolism with a single contrast bolus and breath hold. We sought to determine whether 64-slice computed tomography angiography (CTA) allows for simultaneous visualization of the coronary arteries, thoracic aorta, and(More)
The aim of this study was to show how evidence-based medicine (EBM) techniques can be applied to the appraisal of diagnostic radiology publications. A clinical scenario is described: a gastroenterologist has questioned the diagnostic performance of magnetic resonance cholangiopancreatography (MRCP) in a patient who may have common bile duct (CBD) stones.(More)
PURPOSE To assess the effect of a rapid needle-out patient-rollover time approach on the rate of pneumothorax after computed tomography (CT)-guided transthoracic needle biopsy of pulmonary nodules. MATERIALS AND METHODS The institutional review board approved the study, and all patients gave written informed consent. Between January 2008 and December(More)
Recent technologic advances in cardiac magnetic resonance (MR) imaging have resulted in images with high spatial and temporal resolution and excellent myocardial tissue characterization. Cardiac MR is a valuable imaging technique for detection and assessment of the morphology and functional characteristics of the nonischemic cardiomyopathy. It has gained(More)
Rheumatoid Arthritis (RA) is the most common Connective Tissue Disease (CTD) and represents an increasing burden on global health resources. Interstitial lung disease (ILD) has been recognised as a complication of RA but its potential for mortality and morbidity has arguably been under appreciated for decades. New studies have underscored a significant(More)
OBJECTIVE The objective of this study was to use high-resolution MDCT to assess the relation of the pulmonary vasculature to septic emboli with particular attention to the feeding vessel sign. MATERIALS AND METHODS The MDCT scans of nine patients with septic emboli were retrospectively, blindly evaluated by two observers. A control group of 10 patients(More)
