Embodiments provide a noninvasive quantitative method for detecting extent and/or types of fibrosis in the heart. In embodiments, information pertaining to the extent and/or types of fibrosis may aid in the diagnosis of specific cardiac diseases and heart failure and/or may assist in determining suitable treatment options. Embodiments provide methods and apparatuses for determining the extent of fibrosis in viable and nonviable myocardium, which may then be correlated to heart disease and failure. Thus, in an embodiment, a method of screening individuals for the purpose of heart disease or heart failure prevention may be provided using the detection methodology described herein.

A biological detector includes a conduit for receiving a fluid containing one or more magnetic nanoparticle-labeled, biological objects to be detected and one or more permanent magnets or electromagnet for establishing a low magnetic field in which the conduit is disposed. A microcoil is disposed proximate the conduit for energization at a frequency that permits detection by NMR spectroscopy of whether the one or more magnetically-labeled biological objects is/are present in the fluid.

A process for profiling fluid distribution and analyzing fluid redistribution kinetics in multi-layer absorbent articles is disclosed.

The present disclosure discusses systems and methods for imaging tissue. The system can reduce the amount of vibrations that are transmitted from a magnetic resonance imaging device to a tissue sample. The system can include a stabilization platform with at least one vibration dampener coupled towards either end of the stabilization platform. A fluid reservoir is coupled to the stabilization platform and a resonator is coupled to the exterior of the fluid reservoir.

Gas vesicle protein structures and related compositions, methods, and systems for singleplexed and/or multiplexed magnetic resonance imaging of a target site alone or in combination with ultrasound are described, in which the gas vesicle protein structures provide contrast for the imaging.

The invention relates to a system and a non-invasive method for examining at least parts of the blood fractions, designed for examination of the blood fractions on the basis of at least one magnetic resonance spectroscopy of a human body part, in particular of the human finger. The invention also relates to the use of said system.

A quantification of a particular element comprised in magnetic particles enclosed in a volume involves applying a first time-varying magnetic field to the volume, having a first magnitude and a first frequency and applying a second time varying magnetic field, not parallel with the first magnetic field for causing precession of the magnetized particles. The second magnetic field is an RF field having a second frequency equal to the Larmor-frequency of the particular element. Thereafter the resultant magnetization originating from the volume and modulated by the time-varying field is measured, and at least one frequency component of the resultant magnetization is determined. A power and/or voltage of the at least one frequency component is calculated and a quantity of the magnetic particles enclosed in the volume is determined based thereon.

The present invention relates to novel trityl-nitroxide radicals as polarizing agents for Dynamic Nuclear Polarization (DNP).
