RAS Dataset: A 3D Cardiac LGE-MRI Dataset for Segmentation of Right Atrial Cavitydoi:10.1038/s41597-024-03253-9The current challenge in effectively treating atrial fibrillation (AF) stems from a limited understanding of the intricate structure of the human atria. The objective and quantitative ...
Cardiac MRI imagesFour-dimensionalDatasetArtificial intelligenceThe right ventricular (RV) segmentation is essential for cardiac diagnosis. However, it is hindered by many anatomical and imaging issues. With the emergence of artificial intelligence, the RV segmentation approaches are moving towards learning-...
CMRxRecon: A publicly availablek-space dataset and benchmark to advance deep learning for cardiac MRIdoi:10.1038/s41597-024-03525-4Cardiac magnetic resonance imaging (CMR) has emerged as a valuable diagnostic tool for cardiac diseases. However, a significant drawback of CMR is its slow imaging ...
Dataset invarianceAdversarial learningVentricular coverage assessmentMRICardiac functional parameters, such as, the Ejection Fraction (EF) and Cardiac Output (CO) of both ventricles, are most immediate indicators of normal/abnormal cardiac function. To compute these parameters, accurate measurement of ...
Cardiac MRIDatasetThalassemiaT2* magnetic resonance imagingIron overloadHepatic systemOwing to the invasiveness and low accuracy of other tests, including biopsy and ferritin levels, magnetic resonance imaging (T2 and T2*-MRI) has been considered the standard test for patients with thalassemia (THM)....
Our simulation was based on the Aliev–Panfilov model [61] of electrical excitation in the myocardium and the aforementioned human heart DT-MRI dataset and anatomical model (see Section 2.3 and Section 4). The electrophysiological model is dimensionless and has the following form: ∂𝑢∂...
