Multi-Echo Spin-, Asymmetric Spin-, And Gradient Echo Echoplanar Imaging (Message-EPI) MRI

技術優勢
Only pulse-program of its kind to use quadruple spin-echo and echo-gradient pulses to generate quantitative T2, T2*, or R2' measurements Can easily and readily obtain vascular penetration, cerebral blood volume, vessel architecture, and vessel diameter, density and size data  Can measure tissue oxygenation Can be implemented on current MRI systems
詳細技術說明
UCLA researchers led by Prof. Benjamin Ellingson have developed a new multi component spin-echo and gradient echo pulse program for MR imaging related to brain disease such as stroke or tumor. This pulse program uses quadruple spin-echo and echo-gradient sequences to compute quantitative T2, T2*, or R2' measurements. This allows for direct measurement of several clinically relevant biomarkers for cancer or stroke including: vascular penetration, cerebral blood volume, vessel architecture, and vessel diameter, density and size simultaneously.
*Abstract

Background

Magnetic Resonance Imaging (MRI) relies on programed pulse-schemes (or pulse programs) to generate images. These pulse-programs dictate not only the type of information being obtained, but also the quality of the resultant images. Methods such as spin-echo, and gradient echo sequences are utilized to obtain magnetic resonance (MR) data on tissues samples, this information is then used to generate 2D and 3D images. While many advances in both MRI technology and pulse-program design have pushed the utility and resolution of MRI imaging, many yield limited, qualitative, or highly specific information. The development of a complex pulse-program that combines the power of spin-echo and gradient echo schemes could potentially revolutionize MR image and data acquisition.
