OBJECTIVE Cardiac CT angiography (CTA) is commonly performed after coronary artery bypass grafting surgery (CABG) to assess graft patency, but the images also include parts of the lungs, abdomen, and mediastinum. The purpose of our study was to retrospectively assess the prevalence of unsuspected disease identified on cardiac CTA examinations after CABG and(More)
An 8-year-old girl was evaluated for a mass in the left pulmonary lobe. Her clinical history was remarkable for an intermittent dry cough since the age of 2, with recurrent episodes of purulent sputum and fever. She underwent left lower lobectomy, which was found to be a bronchioloalveolar carcinoma arising in a type 1 congenital pulmonary airway(More)
The traditional treatment of severely impacted fractures of the distal radius involves bridging external fixation and maintaining reduction by applying continuous traction. The recent technique using fixed-angle screws within volar plates is reported restore the radial length and the articular profile whilst avoiding joint distraction. It is also believed(More)
Pleurodesis is frequently performed to prevent recurrence of pneumothorax or recurrent pleural effusion in benign or malignant conditions. In essence, it involves producing an area of adhesion between the parietal and the visceral layers of the pleura. The approach to this procedure can be divided into chemical and mechanical methods. Chemical pleurodesis(More)
BACKGROUND Aortic valve bypass (AVB, apicoaortic conduit) is an alternative to aortic valve replacement (AVR) for high-risk patients with aortic stenosis (AS). The redistribution of blood flow after AVB has been poorly characterized. In order to understand cardiovascular physiology after AVB, we performed cardiac magnetic resonance (CMR) imaging of AVB(More)
Mobile displays may have the ability to increase the flexibility of consulting radiologists if they can be shown not to negatively influence a reader's performance in clinical tasks. The authors report a comparison of a mobile display with a larger liquid crystal display for the task of making a binary decision for the diagnosis of tuberculosis on chest(More)
PURPOSE Cardiac ventricular diverticulum is a rare congenital malformation. The entity is usually asymptomatic but can rarely cause complications and mimic other severe cardiac diseases on imaging. We evaluated the incidence and imaging findings of left and right ventricular diverticula on electrocardiogram-gated 256-slice multidetector computed tomography(More)
Hemoptysis is defined as the expectoration of blood originating from the tracheobronchial tree or pulmonary parenchyma, ranging from 100 mL to 1 L in volume over a 24-hour period. This article reviews the literature on the indications and usefulness of radiologic studies for the evaluation of hemoptysis. The following recommendations are the result of(More)
RATIONALE AND OBJECTIVE The aim of this study was to compare image quality on dedicated and triple rule-out coronary computed tomographic (CT) angiography (CTA) with respect to motion artifacts and the quality of coronary artery opacification. MATERIALS AND METHODS Twenty dedicated coronary CT angiographic studies and 20 emergency department triple(More)
