Inversion Recovery Balanced SSFP: T1 and T2 Measurement Simulation
In this report, inversion recovery (IR) balanced SSFP with the α/2 preparation pulse is simulated for the ideal case where the spin resonant frequency corresponds to the middle of the passband in the balanced SSFP steady-state signal profile. Simulation studies are presented to assess the effects of various choices of T1, T2, and flip angles on the transient signal responses of the IR balanced ...
متن کاملTrue T1 mapping with SMART1Map (saturation method using adaptive recovery times for cardiac T1 mapping): a comparison with MOLLI
Background SMART1Map is a new single-point technique for cardiac T1 mapping [1]. Unlike Look-Locker approaches, such as MOLLI, which yield an “apparent” T1 (T1*), SMART1Map directly measures true T1. Because T1* is a function of imaging parameters, it is always shorter than T1, and correction methods are required to obtain the true T1. This work compared the accuracy of SMART1Map with MOLLI in ...
متن کاملFurther Test and Validation of Saturation-recovery T1 MRI Measurement for Imaging Absolute CBF Change
Introduction: The feasibility for imaging and quantifying absolute change of cerebral blood flow (CBF) using saturation-recovery T1 MRI approach has been previously demonstrated using rat ischemia (decreasing CBF) and hypercapnia (increasing CBF) models at 9.4T. Briefly, the water exchange between the capillary and brain tissues through the blood perfusion will affect the apparent water T1, thu...
متن کامل3D saturation recovery imaging for free breathing myocardial T1 mapping
Background Longitudinal magnetization relaxation time (T1) mapping can overcome limitations of late gadolinium enhancement for the detection of diffuse fibrosis in the myocardium. Several T1 mapping methods have been proposed in recent years; however most of them are limited to 2D breath-hold acquisitions with associated limitations in signal-to-noise ratio (SNR) and spatial resolution. A MOdif...
