After permanent or transient ligation of the left anterior descending artery, we investigated the connection of 18F-FDG derived left ventricular metabolic volume, defect area, and cardiac function in mice. After permanent and transient LAD ligation, permanent and transient LAD ligation positively correlate with LVMV function parameters by the QGS software in a positive manner. FDG derived parameter and cardiac function are discussed in this paper, which provides new insight into 18F-FDG derived LVMV after persistent and transient LAD ligation by longitudinal in 18F-FDG PET imaging and underlines the correlations of the FDG derived parameter and cardiac function.

Purpose: Myocardial infarction's lack of living cardiac cells and cell death is still a significant barrier in preventing heart disease from progressing heart disease. After permanent ligation of the left anterior descending artery inducing myocardial infarction, procedure involving 2--2-methyl-malonic acid in autoradiography and positron emission tomography revealed apoptosis in murine hearts. Fluoro-D-glucose PET imaging localized the infarct area following MI, with 2-deoxy-2-[18F]fluoro-D-glucose PET imaging localized the infarct area following MI. [18F]ML-10 may be a good tracer for apoptosis imaging in a mouse model of permanent LAD ligation in a mouse model.

In this paper, we propose a L 1 penalized LAD estimation based on some linear constraints. We show that the proposed estimation enjoys the Oracle property with adjusted normal variance when the number of the estimated coefficients p is fixed. And when p is much larger than the sample size n is determined, the error bound of estimated estimation is much more pronounced than k log / n.
