Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] The embolism uses sodium alginate microspheres. Digital subtraction machine and image processing workstation use simensArtiszeego digital subtraction contrast machine and workstation. The contrast agent concentration analysis was performed using I-flow software, and the analysis sequence time ranged from 1.33 seconds to 10.13 seconds.

[0033] Using SPSS15.0 software, the results of animal experiments are tested using discrete coefficients, the results of the method of the present invention are tested for consistency with the results of diagnostic experts, and the chi-square test of Kendall's concordance coefficient (Kendall's concordance coefficient) is used, P<0.01, it is considered to have consistency ; Using the correlation coefficient test, P<0.01, considered consistent.

Abstract

The invention discloses a method for quantitatively determining the blood supply level and embolism proportion of tumors, and belongs to a mathematical calculation or data processing method specially suitable for specific application. The method includes the steps that with the start portion of an organ blood supply artery as a reference region and a tumor region as a target region, the enhancement degree area under the curve of the reference region and the target region is calculated with software according to the concentration of contrast media in different regions; then, calculation is performed through the obtained enhancement degree area under the curve of the reference region and the target region to obtain the blood supply level value and the embolism proportion. By means of the method, the blood supply level and the embolism proportion before and after liver cancer interventional treatment can be effectively analyzed and identified through an imageological examination result; the method has great significance in correctly selecting an interventional treatment method, making a treatment plan and improving the liver cancer treatment effect and has broad application prospects.

Description

technical field [0001] The invention belongs to a method of mathematical calculation or data processing specially suitable for specific applications, in particular a method for quantitatively measuring tumor blood supply level and embolism ratio. Background technique [0002] Liver cancer is a common malignant tumor, which is more common in Asia, with an incidence rate of one in ten thousand. Among the primary liver cancers that occur every year in the world, nearly half of them occur in China. Its mortality rate is second only to gastric cancer and lung cancer. It is one of the common malignant tumors that seriously endanger human life and health. It is known for its highly malignant characteristics and extremely poor prognosis. Among the current treatment methods, surgical resection is still the first choice. However, due to the insidious onset of primary liver cancer, the early symptoms are not obvious. Once discovered, most of them are in the middle and late stages, and...
