Organ fat non-invasive quantitative detection system based on magnetic resonance principle

Abstract

The invention discloses an organ fat non-invasive quantitative detection system based on a magnetic resonance principle. The organ fat non-invasive quantitative detection system is characterized in that a radio frequency (RF) subsystem, a portable magnet module and a data processing and display module are adopted to jointly construct a low-field nuclear magnetic resonance system. When the low-field nuclear magnetic resonance system acts on a human body, organs, tissues and cells are not damaged and wounded. Accurate, non-invasive and safe organ fat quantitative detection is achieved, and the organ fat non-invasive quantitative detection system has the advantages of being light, easy to carry, high in cost performance, accurate in quantification and the like. The organ fat non-invasive quantitative detection system is convenient to operate, is not limited by the qualification of operators, achieves one-key detection within a few minutes, is used for rapidly and economically screening related diseases such as NAFLD, metabolic syndrome, non-alcoholic steatohepatitis (NASH) and the like, and has a wide application range. The defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance medical detection, in particular to a non-invasive quantitative detection system for organ fat based on the principle of magnetic resonance. Background technique [0002] About 25% of the global population is suspected to have non-alcoholic fatty liver disease (NAFLD), and many remain undiagnosed due to the lack of feasible, realistic and accurate methods for early detection and monitoring. The current gold standard for diagnosing NAFLD is liver biopsy, which is expensive and invasive, and is not suitable for early detection. Conventional ultrasound imaging is widely used, but it can only provide qualitative information and is highly operator-dependent. In addition, cases of obesity and excess subcutaneous fat are common in NAFLD patients, and ultrasonography is difficult to obtain reliable results. Conventional MRI is an emerging NAFLD status monitoring technique, which has b...
