Embodiment Construction

[0013] The present invention relates to an MRI positioning measurement method for the anteroposterior and left-right diameters of the fourth ventricle of the human body, comprising the following steps: placing the human brain specimen or the subject on the examination bed, taking the supine position, and preparing the gradient back through T1-weighted three-dimensional magnetization The isotropic MRI high-resolution image data is obtained by wave sequence scanning, the image data is imported into the workstation, and the mid-sagittal image of the head is obtained by using the 3D reconstruction software that comes with the workstation, as shown in figure 1 shown; then in figure 1 In the middle, using the three-dimensional reconstruction software of the workstation, a connecting line CD is made through the 3 anterior borders of the optic chiasm and 2 posterior commissures, and then a line CD is made on the midsagittal image through the apex 11 of the fourth ventricle 1 and the ab...

Abstract

The invention discloses an MRI positioning measurement method of anteroposterior diameter and left-right diameter of ventriculus quartus cerebri of human bodies. On an MRI high-resolution image, a line parallel to the connecting line between the cross front edge and the rear linkage is drawn through the top of the ventriculus quartus cerebri and is used as a positioning line for reconstructing the cross section; a cross-section image is reconstructed on the positioning line; and the anteroposterior diameter and the left-right diameter of the ventriculus quartus cerebri are measured according to the cross-section image. The invention eliminates errors caused by inclination of heads of people to be measured, reduces the effect factors on the measuring result by measurement scanning personnel and improves the accuracy and the repeatability of the measuring result.

Description

technical field [0001] The invention relates to the technical field of medical imaging, specifically an MRI positioning and measuring method for the anteroposterior and left-right diameters of the fourth ventricle of a human body. Background technique [0002] The fourth ventricle of the human body is a tent-like irregular structure with the base forward and the tip backward. By using standard and standardized measurement methods to accurately measure the front-to-back diameter and left-right diameter length values ​​of the fourth ventricle of the human body, it is possible to study different ages, Changes of the fourth ventricle of normal people of different genders, understand the size and structure of the fourth brain of normal people, so as to establish a standard database of the fourth ventricle of normal people, and provide reference for medical workers to study the changes in the size of the fourth ventricle value. At present, the measurement methods of the anterior-...
