Anal Chem
. 2025 Mar;
PMID: 40080432
Precision in nuclear magnetic resonance (NMR) spectroscopy and resolution in magnetic resonance imaging (MRI) are thought to be fundamentally limited by the transverse relaxation time. With the recent advent of...

PMID: 38553824
Magnetic susceptibility imaging may provide valuable information about chemical composition and microstructural organization of tissue. However, its estimation from the MRI signal phase is particularly difficult as it is sensitive...

PMID: 37884304
Background And Purpose: Glioblastomas and metastases are the most common malignant intra-axial brain tumors in adults and can be difficult to distinguish on conventional MR imaging due to similar imaging...

. 2023 Sep;
91(2):699-715.
PMID: 37772624
Purpose: To extend quantitative susceptibility mapping to account for microstructure of white matter (WM) and demonstrate its effect on ex vivo mouse brain at 16.4T. Theory And Methods: Previous studies...

PMID: 37392588
Nuclear magnetic resonance (NMR) has been instrumental in deciphering the structure of proteins. Here we show that transverse NMR relaxation, through its time-dependent relaxation rate, is distinctly sensitive to the...

PMID: 37172079
Conventional nuclear magnetic resonance (NMR) enables detection of chemicals and their transformations by exciting nuclear spin ensembles with a radio-frequency pulse followed by detection of the precessing spins at their...

. 2023 Mar;
90(1):353-362.
PMID: 36999746
Purpose: Estimating magnetic susceptibility using MRI depends on inverting a forward relationship between the susceptibility and measured Larmor frequency. However, an often-overlooked constraint in susceptibility fitting is that the Larmor...

. 2022 Dec;
36(5):e4886.
PMID: 36517244
Recently, Ye and colleagues proposed a method for "augmented T1-weighted imaging" (aT W). The key operation is a complex division of gradient-echo (GRE) images obtained with different flip angles. Ye...
