$\textbf{Purpose:}$ To develop a new method for free-breathing 3D extracellular volume (ECV) mapping of the whole heart at 3T. $\textbf{Methods:}$ A cardiac ECV was developed T1 performed before and after contrast agent injection using ECG-gated inversion-recovery sequence with spoiled gradient echo readout. linear tangent space alignment (LTSA) model-based used to reconstruct high-frame-rate dynamic images from (k,t)-space data sparsely sampled along random stack-of-stars trajectory. Joint...
Abstract Purpose To develop a new method for free‐breathing 3D extracellular volume (ECV) mapping of the whole heart at 3 T. Methods A cardiac ECV was developed T 1 performed before and after contrast agent injection using electrocardiogram‐gated inversion recovery sequence with spoiled gradient echo readout. linear tangent space alignment model‐based used to reconstruct high‐frame‐rate dynamic images from (k,t)‐space data sparsely sampled along random stack‐of‐stars trajectory.

Positron emission tomography (PET) has become standard practice in many clinical applications including oncology, cardiology and neurology. Recent developments PET scanners have pushed the limits of these applications, thanks to long axial field view which can improve system sensitivity use time-of-flight (TOF) information spatial resolution. However, cost space requirements for total-body systems created a need flexible, low-cost yet high-sensitivity with large view. Additionally, currently...
