Bicomponent Mapping of Cortical Bone Using a New Interleaved UTE Imaging Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultrashort echo time (UTE) MRI enables direct imaging of cortical bone and quantification of its water compartments via bicomponent T2* modeling. However, conventional approaches require multiple separate dual‐echo scans due to limitations in gradient power. This approach is prone to inter‐scan inconsistencies such as motion and signal

Dynamic RBC‐To‐Membrane Ratio in 129Xe MRI: A Biomarker of Decreased Lung Function in Pulmonary and Vascular Diseases

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To present a method for quantifying dissolved 129Xe spectroscopy using singular value decomposition (SVD) and a dynamic red blood cell (RBC)/membrane ratio as a biomarker of disease. Methods A spectroscopic sequence was performed in 45 subjects (27 healthy, 12 dyspnea of unknown origin [DUO], and 6 pulmonary hypertension [PH ...

A Novel 9‐Channel 1H, 3‐Channel 31P Radiofrequency Coil for Interleaved Multinuclear Studies of Human Calf Muscle at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a double‐tuned calf coil with excellent 1H and 31P performance to study muscle physiology by interleaved 1H/31P MRS and parallel imaging at 7 T. Methods The coil combines three 1H transceive dipoles, six 1H receive‐only loops and three 31P transceive loops, arranged in a nested, half‐cylindrical layout.
