Physics-Informed Self-supervised Deep Learning Reconstruction for Accelerated First-Pass Perfusion Cardiac MRI
نویسندگان
چکیده
First-pass perfusion cardiac magnetic resonance (FPP-CMR) is becoming an essential non-invasive imaging method for detecting deficits of myocardial blood flow, allowing the assessment coronary heart disease. Nevertheless, acquisitions suffer from relatively low spatial resolution and limited coverage. Compressed sensing (CS) methods have been proposed to accelerate FPP-CMR achieve higher resolution. However, long reconstruction times widespread clinical use CS in FPP-CMR. Deep learning techniques based on supervised emerged as alternatives speeding up reconstructions. these approaches require fully sampled data training, which not possible obtain, particularly high-resolution images. Here, we propose a physics-informed self-supervised deep approach accelerating scans hence facilitate high imaging. The provides high-quality images 10x undersampled without using reference data.

Combination of compressed sensing and parallel imaging for highly accelerated first-pass cardiac perfusion MRI.
First-pass cardiac perfusion MRI is a natural candidate for compressed sensing acceleration since its representation in the combined temporal Fourier and spatial domain is sparse and the required incoherence can be effectively accomplished by k-t random undersampling. However, the required number of samples in practice (three to five times the number of sparse coefficients) limits the accelerat...
متن کاملAccelerated first pass cardiac perfusion MRI using improved k - t SLR
Routinely trade-offs between the spatio-temporal resolution, volume coverage and SNR are done in first pass cardiac perfusion MRI due to the restricted imaging acquisition window (usually of the order of 300 to 400 msec per heart beat). In this paper, we demonstrate the use a low rank and sparse reconstruction scheme (k − t SLR) in obtaining highly accelerated first pass perfusion MR images and...
متن کاملHighly-Accelerated First-Pass Cardiac Perfusion MRI Using Compressed Sensing and Parallel Imaging
INTRODUCTION: First-pass cardiac perfusion MRI is a promising modality for the assessment of coronary artery disease. Recently developed dynamic parallel imaging techniques, such as k-t SENSE [1] and k-t GRAPPA [2], can be used to perform up to 10-fold accelerated perfusion imaging by exploiting the difference in coil sensitivities and spatio-temporal correlations. Such techniques can be used t...
متن کاملIntegrated quantitative first-pass cardiac perfusion MRI protocol
Methods A multi-slice saturation recovery (SR) pulse sequence with sequential SR time delays (TD) after a non-selective saturation pulse [2] was implemented at 3T (Fig. 1). The rationale for this acquisition scheme was to acquire a dedicated arterial input function (AIF) image with a short TD (50ms) in the aortic root and short-axis myocardial images with longer TD values (~150-400ms), to allow...
متن کاملSystolic 3D first-pass myocardial perfusion MRI
Introduction: First-pass myocardial perfusion imaging (MPI) is now an established tool for the assessment of ischemic heart disease, and the most widely used protocols involve 2D multi-slice acquisition. Three-dimensional (3D) MPI is potentially advantageous due to its contiguous spatial coverage and high SNR [1], and has been recently shown to be more accurate than 2D multi-slice techniques in...
