《Diagnostic and Interventional Imaging》：Normal variations of myocardial T1, T2 and T2* values at 1.5 T cardiac MRI in sex-matched healthy volunteers 【字体： 大中小】 时间：2025年06月03日 来源：Diagnostic and ...

在法医尸检中，颅内出血年龄判断存挑战。本研究针对 200 例自然及创伤性颅内出血案例，借助 PMMR 探究不同时期出血的 T1、T2 信号特征，分析 PMI 和腐败程度（RAI）影响。发现信号模式与临床 MRI 相似，且高 RAI 未显著影响信号，为法医精准判断提供依据。

T2 (transverse relaxation time) is the time constant which determines the rate at which excited protons reach equilibrium or go out of phase with each other. It is a measure of the time taken for ...

or enhancement on normal MRI scans, they may affect myocardial nuclear magnetic resonance (NMR) properties, including T1 and T2 relaxation times. Estimates of relaxation times can be produced ...

T2 and proton density. MR scans that bring out T1 contrast are defined as T1-weighted. The primary basis for different types of contrast in MRI is the choice of two scan parameters: TR (repletion ...

The new study compared MRI scanner measurements of a value called T1, a property of water molecules that can depend on the surrounding tissue. T1 of the pixels in images is one of the parameters ...

“Importantly, our findings generalized across datasets and MRI contrasts. Our training used only FLAIR and T1 images, yet the model successfully processed new contrasts (like PD and T2) from ...
