Simultaneous dual contrast weighting using double echo rapid acquisition with relaxation enhancement (RARE) imaging

Abstract

2in1-RARE offers simultaneous acquisition of images of anatomical (PD) and functional (T2 *) contrast. It presents an alternative to address scan time constraints frequently encountered during sequential acquisition of T2 * or PD-weighted RARE.

How bold is blood oxygenation level‐dependent (BOLD) magnetic resonance imaging of the kidney? Opportunities, challenges and future directions

“…), explorations into simultaneous /T 2 ‐sensitized MRI to reduce scan times (Fuchs et al . ), application of mapping techniques free of image distortion (Niendorf , Heinrichs et al . ) and development of novel radiofrequency antennas to enhance the sensitivity of MR detectors (Dieringer et al .…”

Detailing the Relation Between Renal T2* and Renal Tissue pO2 Using an Integrated Approach of Parametric Magnetic Resonance Imaging and Invasive Physiological Measurements

“…Notwithstanding this success, our findings generated novel questions about the renal These efforts should make use of the advanced capabilities of MR-PHYSIOL by including parallel imaging techniques to improve the temporal resolution [59][60][61][62], by investing into dual contrast techniques for simultaneous T 2 */T 2 weighted MRI [63], by driving T 2 * mapping techniques free of image distortion [64] but also MR based assessment of renal blood volume [65] and by probing tubular volume fraction using diffusion weighted or intra-voxel incoherent motion techniques [43,[66][67][68][69], while blood sampling may be employed to examine the role of shifts in the oxyHb dissociation curve. These explorations are essential before the quantitative capabilities of parametric MRI can be translated from experimental research to improved clinical understanding of hemodynamics/oxygenation in kidney disorders.…”

High spatial resolution in vivo magnetic resonance imaging of the human eye, orbit, nervus opticus and optic nerve sheath at 7.0 Tesla

“…Due to the RF power deposition issues imaging techniques that include trains of RF refocusing pulses, e.g. fast spin-echo techniques can easily reach and exceed the SAR limits at 7.0 T. Therefore further research is required to extend the feasibility of ultrafast low angle spin-echo imaging techniques, as already established for functional and anatomical brain imaging, (Niendorf, 1999, Fuchs et al, 2013 to ophthalmic MRI.…”
