AbstractPurpose18F-fluorodeoxyglocose positron emission tomography (FDG PET) plays a significant role in the diagnosis of cardiac sarcoidosis (CS). Texture analysis is a group of computational methods for evaluating the inhomogeneity among adjacent pixels or voxels. We investigated whether texture analysis applied to myocardial FDG uptake has diagnostic value in patients with CS.MethodsThirty-seven CS patients (CS group), and 52 patients who underwent FDG PET/CT to detect malignant tumors with any FDG cardiac uptake (non-CS group) were studied. A total of 36 texture features from the histogram, gray-level co-occurrence mat...

​Seventy-five percent of trauma injuries involve some kind of thoracic insult, a quarter of which need a procedural intervention like a chest tube. (Surg Clin North Am 2007;87[1]:95; Long-term illness, lung disease, and post-operative complications may cause pleural effusions or a pneumothorax, so treating these conditions quickly can significantly decrease patient morbidity and mortality. Other indications for chest tube placement include:Trauma: Pneumothorax, hemopneumothorax, or tension pneumothoraxLong-term illness: Pleural effusion (cancer, pneumonia)Infection: Empyema, purulent pleuriti...

ConclusionEPS may help with risk stratification in patients with CS and abnormal imaging, especially those without conventional indications for ICD placement. Among patients with LVEF>35% and no history of prior VA, a negative EPS has good positive and negative predictive value for future VA events.

Authors: Boutagy NE, Feher A, Alkhalil I, Umoh N, Sinusas AJ Abstract Multimodality cardiovascular imaging is routinely used to assess cardiac function, structure, and physiological parameters to facilitate the diagnosis, characterization, and phenotyping of numerous cardiovascular diseases (CVD), as well as allows for risk stratification and guidance in medical therapy decision-making. Although useful, these imaging strategies are unable to assess the underlying cellular and molecular processes that modulate pathophysiological changes. Over the last decade, there have been great advancements in imaging instrumenta...

AbstractPurpose of ReviewThe purpose of this paper is to provide an updated review of recent advances in protocols for positron emission tomography (PET) or PET/computed tomography (PET/CT) imaging in patients with sarcoidosis.Recent FindingsThere has been more research focused on developing newer and improved PET imaging modalities to diagnose and follow-up cardiac sarcoidosis (CS). Fluorine-18-fluorodeoxyglucose (18F- FDG)-PET are widely used to diagnose CS, with or without concurrent rest nuclear myocardial perfusion study. There have been various patient preparation strategies for FDG PET/CT in CS. Interpretation crite...

Authors: Yada H, Soejima K Abstract Sarcoidosis is a multisystem granulomatous disorder of unknown etiology. The annual incidence of systemic sarcoidosis is estimated at 10-20 per 100,000 individuals. Owing to the recent advances in imaging modalities, cardiac sarcoidosis (CS) is diagnosed more frequently. The triad of CS includes conduction abnormality, ventricular tachycardia, and heart failure. Atrial and ventricular arrhythmias are caused by either inflammation or scar formation. Inflammation should be treated with immunosuppression and antiarrhythmic agents and scar formation should be treated with antiarrhyth...
