Fiber bundle length and cognition: a length-based tractography MRI study

Studies on length-weight and length-length relationships of a catfish Eutropiichthyes vacha Hamilton (Schilbeidae: Silurifo-

Present study describes the length-weight (LWR) and length-length (LLR) relationships of a freshwater catfish Eutropiichthyes vacha Hamilton from Indus River, Sindh, Pakistan. A total of 281 specimen of E. vacha were collected from fisherman?s catch from February 2005 to January 2006, are used for this study. The parameters a and b of the length-weight relationship were calculated as W= aLb are...

Anisotropic Smoothing Improves DT-MRI-Based Muscle Fiber Tractography

PURPOSE To assess the effect of anisotropic smoothing on fiber tracking measures, including pennation angle, fiber tract length, and fiber tract number in the medial gastrocnemius (MG) muscle in healthy subjects using diffusion-weighted magnetic resonance imaging (DW-MRI). MATERIALS AND METHODS 3T DW-MRI data were used for muscle fiber tractography in the MG of healthy subjects. Anisotropic s...

Application of a Novel Quantitative Tractography-based Analysis of Diffusion Tensor Imaging to Examine Fiber Bundle Length in Human Cerebral White Matter.

This paper reviews basic methods and recent applications of length-based fiber bundle analysis of cerebral white matter using diffusion magnetic resonance imaging (dMRI). Diffusion weighted imaging (DWI) is a dMRI technique that uses the random motion of water to probe tissue microstructure in the brain. Diffusion tensor imaging (DTI) is an extension of DWI that measures the magnitude and direc...

construction and validation of a computerized adaptive translation test (a receptive based study)

آزمون انطباقی رایانه ای (cat) روشی نوین برای سنجش سطح علمی دانش آموزان می باشد. در حقیقت آزمون های رایانه ای با سرعت بالایی به سمت و سوی جایگزین عملی برای آزمون های کاغذی می روند (کینگزبری، هاوسر، 1993). مقاله حاضر به دنبال آزمون انطباقی رایانه ای برای ترجمه می باشد. بدین منظور دو پرسشنامه مشتمل بر 55 تست ترجمه میان 102 آزمودنی و 10 مدرس زبان انگلیسی پخش گردید. پرسشنامه اول میان 102 دانشجوی س...
