Quantitative cardiac MR assessment of left ventricular diastology

Background Cardiac MR (CMR) is the accepted gold standard for the assessment of myocardial scar and biventricular systolic function. Bright blood cine imaging with phase-contrast mitral inflow assessment has shown promise for the evaluation of left ventricular (LV) diastology. The purpose of this study is to evaluate the accuracy of LV diastolic function grading by CMR, using Doppler echocardio...

Ultrafast Cine cardiac MRI in the assessment of left ventricular diastology

Methods 18 self-reported healthy volunteers (12 men, average age 35 years) and 6 patients with diastolic dysfunction (4 men, average age 52 years) underwent cardiac MRI on an investigational 1.5T cardiovascular magnet (Aera, Siemens Medical Solutions, Erlangen Germany). All subjects underwent ultrafast cine MR imaging in four and two chamber orientations (nominal TR 5.5 15.3 msec, heart rate de...

Ibn Sīnā’s Practical Philosophy

This article is a brief review of Ibn Sīnā’s practical philosophy. It begins with a discussion of the Platonic, Aristotelian, and Neo-Platonic influences on Ibn Sīnā’s practical philosophy, as well as the influence of Fārābī and of Islamic religious teachings. The creative synthesis invented by Ibn Sīnā requires a particular view of the relation between religion and philosophy in such a manner ...

The association among MDCT-derived three-dimensional visceral adiposities on cardiac diastology and dyssynchrony in asymptomatic population

BACKGROUND Visceral adipose tissue, a biologically active fat depot, has been proposed as a reliable marker for visceral adiposity and metabolic abnormalities. Effects of such adiposity on LV diastolic function and dyssynchrony remained largely unknown. METHODS We assessed pericardial fat (PCF) and thoracic peri-aortic fat (TPAF) by three-dimensional (3D) volume-vender multi-detector computed...
