Magnetic resonance imaging (MRI) is well known as a non-invasive diagnostic imaging technique available to clinical medicine. MRI provides high spatial resolution images with flexible soft tissue contrast as the signal encoding is more complicated than other imaging modalities.
Machine learning, especially deep learning, has become a popular research topic to solve nonlinear problems. It has...
Introduction: Hyperpolarized 129Xe lung MRI is an efficient technique used to investigate and assess pulmonary diseases. However, the longitudinal observation of the emphysema progression using hyperpolarized gas MRI-based Apparent Diffusion Coefficient (ADC) can be problematic, as the disease-progression can lead to increasing unventilated-lung areas, which likely excludes the largest ADC...
INTRODUCTION: A non-invasive imaging technique inhaled hyperpolarized (HP) 129Xe magnetic resonance imaging (MRI) is presently employed to assess lung structure and function1. It is possible to quantify the ventilation/perfusion (V/P) of the lungs simultaneously using this MRI technique because the solubility of xenon in lung tissues is higher compared to other imaging gases. This measurement...
Introduction: It has recently been shown1,2 that combining Compressed-Sensing with the Stretched-Exponential Model (SEM) can significantly increase SNR of accelerated/undersampled MR images. The reconstruction uses an exponentially decaying signal trend across a group of images assumed to represent the decaying density of resonant isotope in lungs after each wash-out breath....
