Improved accelerated breath-hold radial cine image reconstruction by acquiring additional free-breathing data between breath-holds
نویسندگان
چکیده
Background Evaluation of cardiac function is clinically performed using multi-slice breath-hold (BH) acquisition, in which patient breathes for a period of 40-60 seconds between a BH of 10-12 seconds. This results in suboptimal data acquisition efficiency. In this study, we propose to take advantage of the time between multiple BHs to acquire additional free-breathing (FB) data that can be used in the reconstruction of undersampled BH acquisition without increasing the total scan time.

Compressed sensing reconstruction for undersampled breath-hold radial cine imaging with auxiliary free-breathing data.
PURPOSE To improve compressed sensing (CS) reconstruction of accelerated breath-hold (BH) radial cine magnetic resonance imaging (MRI) by exploiting auxiliary data acquired between different BHs. MATERIALS AND METHODS Cardiac function is usually assessed using segmented cine acquisitions over multiple BHs to cover the entire left ventricle (LV). Subjects are given a resting period between adj...
متن کاملNonlinear profile order for 3D hybrid radial acquisition applied to self-gated free-breathing cardiac cine MRI
Background Self-gated free-breathing 3D cardiac cine MRI has been widely introduced, which provides similar image quality and functional measurements as breath-hold technique [1-3]. In self-gated free-breathing cardiac cine MRI, respiratory and cardiac motions are unpredictable during the acquisition especially in retrospective reconstruction. Therefore, nonuniform k-space distribution is a maj...
متن کاملRetrospective reconstruction of high temporal resolution cine images from real-time MRI using iterative motion correction.
Cardiac function has traditionally been evaluated using breath-hold cine acquisitions. However, there is a great need for free breathing techniques in patients who have difficulty in holding their breath. Real-time cardiac MRI is a valuable alternative to the traditional breath-hold imaging approach, but the real-time images are often inferior in spatial and temporal resolution. This article pr...
متن کاملSelf-Gated Free-Breathing 3D Coronary CINE Imaging with Simultaneous Water and Fat Visualization
The aim of this study was to develop a novel technique for acquiring 3-dimensional (3D) coronary CINE magnetic resonance images with both water and fat visualization during free breathing and without external respiratory or cardiac gating. The implemented multi-echo hybrid 3D radial balanced Steady-State Free Precession (SSFP) sequence has an efficient data acquisition and is robust against mot...
متن کاملHigh spatial and temporal resolution cardiac cine MRI from retrospective reconstruction of data acquired in real time using motion correction and resorting.
Cine MRI is used for assessing cardiac function and flow and is typically based on a breath-held, segmented data acquisition. Breath holding is particularly difficult for patients with congestive heart failure or in pediatric cases. Real-time imaging may be used without breath holding or ECG triggering. However, despite the use of rapid imaging sequences and accelerated parallel imaging, real-t...
