The ability of magnetic resonance imaging (MRI) to obtain multiple imaging contrasts depicting various properties of tissue makes it an excellent tool for in-vivo differential diagnosis. Multi-contrast MRI (mcMRI) exams (e.g. \(T_2\)-w, FLAIR-\(T_2\)

Purpose: In brain positron emission tomography/magnetic resonance imaging (PET/MRI), the major challenge of zero-echo-time (ZTE)-based attenuation correction (ZTAC) is the misclassification of air/tissue/bone mixtures or their boundaries. Our study a

Accurate quantification of uptake on PET images depends on accurate attenuation correction in reconstruction. Current MR-based attenuation correction methods for body PET use a fat and water map derived from a 2-echo Dixon MRI sequence in which bone

MR-based attenuation correction is instrumental for integrated PET/MR imaging. It is generally achieved by segmenting MR images into a set of tissue classes with known attenuation properties (e.g., air, lung, bone, fat, soft tissue). Bone identificat

Attenuation correction is critical to accurate PET quantitation. Accurate and robust attenuation correction remains challenging in hybrid PET/MR because it is difficult to segment bones, internal air and lungs accurately in MR images and MR often suf
