Multiple 3D inversion recovery imaging for volumeT1mapping of the heart

3D FLAIRED: 3D fluid attenuated inversion recovery for enhanced detection of lesions in multiple sclerosis.

Contrast optimization of a three-dimensional (3D) Fluid-attenuated inversion recovery (FLAIR) sequence is examined in the context of multiple sclerosis. In order to develop 3D FLAIR for enhanced detection of lesions, an iterative approach based on theoretical considerations was used. The 3D FLAIR sequence was systematically acquired with incremental parameter changes on a single subject with mu...

3D real inversion recovery MR imaging for the visualization of endolymphatic hydrops.

The effect of inversion times on the minimum signal intensity of the contrast agent concentration using inversion recovery t1-weighted fast imaging sequence

  Background :Inversion recovery (IR) pulse sequences can generate T1-weighted images with a different range of inversion time (TI) to suppress or null the signal intensity (SI) for a specified tissue. In this study, we aimed to investigate the effect of TI values on the concentration of the contrast agent, which leads to a minimum signal intensity, using an inversion recovery T1-weighted 3-dim...

The Assessment of Endolymphatic Hydrops with High-resolution 3D Real Inversion Recovery and 3D Fluid Attenuated Inversion Recovery Sequences

Since the initial study by Nakashima et al. [1] who demonstrated that endolymphatic hydrops in patients with Ménière’s disease can be visualized using MR imaging following an intratympanic injection of gadolinium, this topic has gained strong clinical interest internationally [2–13]. The two most common sequences used in the evaluation of endolymphatic hydrops are a 3D Fluid Attenuated Inversio...

3D Double Inversion Recovery for High Resolution Gray Matter Brain Imaging

Gray matter (GM) images with high spatial resolution are obtained at 1.5T with a new multislab 3D double inversion recovery sequence that selectively suppresses cerebrospinal fluid (CSF) and white matter (WM). Images show a clear delineation of GM from WM and CSF, also for small GM structures such as the entorhinal cortex, of importance in Alzheimer's disease. Feasibility is demonstrated for th...
