the impact of using inspirational quotes on abstract vocabulary recall
the present study is an attempt to investigate the potential impact of inspirational quotes on improving english abstract vocabulary recall. to achieve this goal, a multiple choice language proficiency test of 60 items including vocabulary and grammar component was administered to a sample of 63 second-semester male and female students whose age ranged between 17 to 22 and they were studying en...
15 صفحه اولBlind estimation of the arterial input function in dynamic contrast-enhanced MRI using purity maximization.
Uncertainty in arterial input function (AIF) estimation is one of the major errors in the quantification of dynamic contrast-enhanced MRI. A blind source separation algorithm was proposed to determine the AIF by selecting the voxel time course with maximum purity, which represents a minimal contamination from partial volume effects. Simulations were performed to assess the partial volume effect...
متن کاملAutomatic selection of arterial input function on dynamic contrast-enhanced MRI images: comparison of different methods
gadolinium images by deconvolution given the arterial input function, AIF(t), and tissue concentration, C(t),: C(t)=CBF٠[AIF(t)⊗R(t)], where R(t) is the tissue residue function. Often AIF is found by manually inspecting tracer concentration maps which is very time consuming and operator dependent. In our study we compare 5 methods of AIF automatic selection, including a novel one. The performan...
متن کاملCorrection of arterial input function in dynamic contrast-enhanced MRI of the liver.
PURPOSE To develop a postprocessing method to correct saturation of arterial input function (AIF) in T1-weighted dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for quantification of hepatic perfusion. MATERIALS AND METHODS The saturated AIF is corrected by parameterizing the first pass of the AIF as a smooth function with a single peak and minimizing a least-squares error in f...
متن کاملFully-Automatic Determination of the Arterial Input Function for Dynamic Contrast-Enhanced Pulmonary MR Imaging
Recent studies have shown that dynamic contrast-enhanced pulmonary MR imaging (DCE-pMRI) is a very appropriate imaging technique for the clinical assessment of lung diseases. For the quantitative analysis of pulmonary blood flow (PBF), pulmonary blood volume (PBV), and mean transit time (MTT) an arterial input function (AIF) of the contrast agent entering the lung is required. The AIF is usuall...
