Native myocardial T1 and ECV with age and gender developing normal reference ranges - a 94 healthy volunteer study
Background Measurement of native T1 and extracellular volume fraction (ECV) allow quantification of diffuse myocardial fibrosis. Normal references ranges are not definitively established. The concept of increasing fibrosis with age is widely held, despite a lack of supportive evidence from tissue studies some of which say the opposite (Olivetti 1991) or point to other age changes eg myocardial ...

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولAge and sex corrected normal reference values of T1, T2 T2* and ECV in healthy subjects at 3T CMR
BACKGROUND Myocardial T1, T2 and T2* imaging techniques become increasingly used in clinical practice. While normal values for T1, T2 and T2* times are well established for 1.5 Tesla (T) cardiovascular magnetic resonance (CMR), data for 3T remain scarce. Therefore we sought to determine normal reference values relative to gender and age and day to day reproducibility for native T1, T2, T2* mapp...
متن کاملAge-gender reference values of native myocardial T1 at 1.5T and 3T: comparison of MOLLI and shMOLLI
Methods Ninety-nine subjects with no history of cardiovascular or systemic disease or regular medication underwent native T1 imaging with modified (MOLLI; 3,3,5) and shortened modified look-locker inversion recovery sequence (shMOLLI; 1,1,5) at either 1.5T or 3T. The images were analyzed using an Osirix plug-in with manual motion correction of the ROI placed conservatively within the septal myo...
