T2- and T2*-weighted High-resolution Fmri at 7t Using Non-balanced Ssfp

Introduction Non-balanced Steady-state free precession (nb-SSFP) has been proposed as an alternative sequence for T2-weighted BOLD fMRI at high field strength [1]. nb-SSFP is attractive because of low rf power deposition and low image distortion, and the possibility of acquiring the T2-weighted S2 signal together with the T2*-weighted S1 signal resembling SE and GE signal characteristics respec...

Transient Balanced SSFP Imaging with Increased Signal by Variable Flip Angles

INTRODUCTION: Often in balanced steady state free precession (bSSFP) acquisitions, physiological motion or use of contrast preparation mechanisms limit the acquisition block length. Therefore, acquisition occurs intermittently and during the transient (as opposed to steady state). This work presents a method for calculating variable flip angles for bSSFP acquisition to generate echoes at predef...

Cardiac and Hepatic T2*-Weighted Magnetic Resonance Imaging

Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...

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 ...

T2 mapping using T2prepared-SSFP: Optimizing echo time, flip angle and parameter fitting

Introduction: T2 Mapping using T2-prepared (T2p) Steady State Free Precession (SSFP) has become increasingly popular. In this technique, multiple images are acquired, each with a different T2p time; a mono-exponential decay curve is fit to the pixel-wise intensities to generate a map of the T2 relaxation times. The T2p consists of non-selective rf pulses and is robust against B0 and B1 inhomoge...
