Superselective pseudocontinuous arterial spin labeling.
A new technique for the imaging of flow territories of individual extra- and intracranial arteries is presented. The method is based on balanced pseudocontinuous arterial spin labeling but employs additional time-varying gradients in between the radiofrequency pulses of the long labeling train. The direction of the additional gradient vector is perpendicular to the selected artery and its azimu...
متن کاملReduction in Cerebral Perfusion after Heroin Administration: A Resting State Arterial Spin Labeling Study
Heroin dependence is a chronic relapsing brain disorder, characterized by the compulsion to seek and use heroin. Heroin itself has a strong potential to produce subjective experiences characterized by intense euphoria, relaxation and release from craving. The neurofunctional foundations of these perceived effects are not well known. In this study, we have used pharmacological magnetic resonance...
متن کاملVessel-encoded arterial spin-labeling using pseudocontinuous tagging.
A new signal-to-noise ratio (SNR) efficient method is introduced for the mapping of vascular territories based on pseudocontinuous arterial spin labeling (ASL). A pseudocontinuous tagging pulse train is modified using additional transverse gradient pulses and phase cycling to place some arteries in a tag condition, while others passing through the same tagging plane are in a control condition. ...
متن کاملfocus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes
چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولKinetic Study of Bone Marrow Perfusion Using Arterial Spin Labeling
Introduction: Dynamic contrast-enhanced MRI (DCE-MRI) studies have shown how bone perfusion is altered in some bone diseases, such as osteoporosis (1) and osteoarthritis (2). Kinetic modeling study of bone perfusion in osteoarthritis (2) showed how quantitative analysis increases our understanding of the pathophysiological processes behind the altered perfusion. However, contrast injection in D...
