Embodiment Construction

[0025] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0026] refer to figure 1 As shown, the method for measuring the local water distribution volume of the human brain in the front A% area of ​​the present invention as the reference area is a PET / H method for the local water distribution volume of the human brain. 2 15 O non-invasive quantitative measurement method, which can quantitatively measure the human brain pixel by pixel, and then generate functional images of the local water distribution volume of the human brain. In order to realize the above-mentioned purpose of the invention, the present invention is achieved by taking the following technical solutions:

[0027] The method for quantitatively measuring the volume of distribution of human brain local water as a reference area in the front A% area is characterized in that:

[0028] (1) PET / H for human brain 2 15 O dynamic scan...

Abstract

The invention provides a human brain local water distribution volume determination method with a front A% area as the reference area. The method comprises the steps of firstly performing PET / H2150 dynamic scanning on a human brain; secondly calculating the relative water distribution volume value P1 of each to-be-determined part in the human brain with the front A% area of the human brain as the reference area; thirdly, performing normalization processing of the human brain after calculating the relative water distribution volume value P1 of each part in the human brain. An obtained value is different from the absolute water distribution volume of the part only by a proportional constant, and the value is used as the index of the absolution water distribution volume. The method requires no dynamic arterial blood drawing, possibly-fuzzy template or model, and manual intervention such as complex correction, thereby facilitating automatic processing of a computer; the determined result does not differ from that of an accurate local water distribution volume quantitative determination method, so that the method enjoys a bright application prospect.

Description

technical field [0001] The invention relates to a method for measuring the local water distribution volume of the human brain, in particular to a method for measuring the local water distribution volume of the human brain using the front A% area as a reference area. The invention belongs to the field of biological and medical imaging. Background technique [0002] Using Positron Radionuclides 15 O labeled water (i.e. H 2 15 O) Positron Emission Tomography (PET) method (abbreviated as PET / H) as imaging agent 2 15 O method) is to carry out PET dynamic scanning after intravenous injection of H2O, and then use the Kety-Schmidt single-chamber model (see Kety SS. (1951) The theory and applications of the exchange of inert gas at the lungs and tissues. Pharmacol Rev 3: 1-41.) and other methods to quantitatively calculate the local water distribution volume pixel by pixel, so that the image of the local water distribution volume can be generated. [0003] In the early quantita...
