Background and objective The Modified Look-Locker Inversion-Recovery (MOLLI) sequence (Messroghli, et al, JMRI, 2007) was optimized for myocardial T1 mapping on 1.5T. However, little data exists on T1 mapping at 3T. The standard MOLLI sequence uses three inversion-recovery blocks to acquire 11 images over 17 heartbeats (HB). The long breath hold could limit its clinical application in patients ...

SUMMARY The purpose of this study was to determine whether dual-echo fast fluid-attenuated inversion recovery MR imaging and corresponding T2 brain maps can show different zones in the affected white matter of patients with cerebral X-linked adrenoleukodystrophy. Ten male patients with cerebral X-linked adrenoleukodystrophy underwent imaging performed using dual-echo fast fluid-attenuated inver...

Multiple sclerosis (MS) is the most common chronic inflammatory demyelinating disease of central nervous system (CNS). MS diagnosis and monitoring are mostly based on Magnetic Resonance Imaging (MRI). This study aims to compare a double inversion recovery MRI sequence with fluid-attenuated in Sclerosis brain. A was conducted 75 patients whose aged between 10 70 years who were having brain

BACKGROUND AND PURPOSE We investigated whether focal hyperintensity on fluid-attenuated inversion recovery image within acute infarcts is associated with symptomatic intracerebral hemorrhage (SICH) after thrombolysis. METHODS Patients with acute ischemic stroke who underwent MRI screening before thrombolysis were enrolled. The presence of focal fluid-attenuated inversion recovery hyperintensi...

PURPOSE To develop arrhythmia-insensitive inversion recovery sequences for improved visualization of myocardial scar and quantification of diffuse fibrosis. METHODS A novel preparation pre-pulse, called saturation pulse prepared heart-rate-independent inversion recovery, is introduced, which consists of a combination of saturation and inversion pulses to remove the magnetization history in ea...

Brain T1 mapping has important clinical applications in detecting brain disorders. Conventional T1 mapping techniques are usually based on inversion recovery spin echo (IRSE) imaging or its more time-efficient counterpart inversion recovery fast spin echo (IRFSE) imaging because they can deliver good image quality. Multiple inversion times are required to accurately estimate T1 over a wide rang...

A 66-year-old man underwent ventriculoperitoneal shunting for communicating hydrocephalus. MRI 10 months postoperatively, done for transient headache, showed new fluid-attenuated inversion recovery/T2 hyperintensities within the corpus callosum (figure), while examination revealed improved gait and bladder control with no evidence of a callosal disconnection syndrome. Figure Fluid-attenuated in...

Introduction Double Inversion Recovery (DIR) [1] and Flow Sensitive Dephasing (FSD) [2] have been used to suppress arterial signal in vessel wall imaging. However, the “black blood” effect of DIR and FSD depends on blood flow, which makes these techniques less effective with slow or in-plane flow. In this work, T1 and T2 differences between blood and vessel wall were exploited using a T2-prepar...
