Embodiment 1

[0022] figure 1 It shows a schematic structural diagram of an automatic quantitative evaluation system for whole body fat using MR technology according to Embodiment 1 of the present invention; figure 1 As shown, the system includes: an image information management module 10, an image recognition module 20, an image quality judgment module 30, a first anatomical segmentation module 40, a second anatomical segmentation module 50, a calculation module 60 and a structured report module 70, wherein,

[0023] The image information management module 10 is connected to the image recognition module 20, and is used to transmit the patient's DICOM image to the image recognition module 20 through the DICOM protocol when the patient has taken the magnetic resonance examination item of body fat detection;

[0024] Wherein, the image information management module is a RIS (Radiology Information System) system.

[0025] The image recognition module 20 is connected with the image information...

Embodiment 2

[0041] image 3 It shows a schematic structural diagram of an automatic quantitative evaluation system for whole body fat using MR technology according to Embodiment 2 of the present invention, as image 3 As shown, the second anatomical segmentation module 50 also includes a label judging unit 502, which is used to judge whether the anatomical label of the fat interval is compliant based on the diagnostic data. Whether the volume is within the second preset threshold, judge whether the spatial relationship of the adjacent fat interval anatomical labels is correct, judge the shapes of different fat interval anatomical labels, and send the judgment result to the structured report module 70; if the fat interval anatomical labels If it is compliant, the diagnostic data will be sent to the calculation module 60 , and if the fat interval anatomical label is not compliant, then the third prompt information and the type of non-compliance will be sent to the structured report module 7...

Embodiment 3

[0045] Figure 4Shows a flow chart of the automatic quantitative evaluation method for whole body fat using MR technology according to Embodiment 3 of the present invention; Figure 4 As shown, the method includes the following steps:

[0046] Step S301, when the patient takes a full body fat detection MRI examination item, the image information management module transmits the patient's DICOM image to the image recognition module through the DICOM protocol;

[0047] Among them, the image information management module is RIS (Radiology Information System) system;

[0048] Step S302, the image recognition module recognizes the body position of the DICOM image based on the DICOM image header file information, and judges whether the DICOM image matches the magnetic resonance examination item of the whole body fat detection, if the DICOM image matches the magnetic resonance examination item of the whole body fat detection, Then extract the GRE DIXON sequence image and / or T1WI seq...

Abstract

The invention provides a system for performing automatic quantitative evaluation on whole-body fat by using a magnetic resonance (MR) technology. After a patient is subjected to a magnetic resonance examination item for fat detection, an image recognition module extracts GRE DIXON sequence images and / or T1WI sequence images; an image quality judgment module performs quality analysis on extracted sequence images; after a first anatomic segmentation module segments non-adipose tissues on qualified images, a second anatomic segmentation module segments subcutaneous fat, muscle and bone fat, visceral fat and special areas on third image, and coordinates of fat septa are set for all the areas and fat septum anatomic labels are set; a calculation module calculates a measured value of each fat septum; and a structured reporting module integrates all processed data and images, stores all processed data and images, and outputs diagnostic images. The invention further discloses a method for performing automatic quantitative evaluation on the whole-body fat by using the MR technology. The system and the method can be accurately and quantitatively measure sizes of the adipose tissues and automatically transmit the sizes into a report, so that the working efficiency of an imaging doctor is improved; and the system and the method can be applied to actual clinical medicine.

Description

technical field [0001] The invention relates to the field of medical information, more specifically, to an automatic quantitative evaluation system and method for whole body fat using MR technology. Background technique [0002] In recent years, due to the increasing incidence of obesity and related metabolic abnormalities, it is required to evaluate the quantitative information of whole body fat when clinically evaluating the condition of patients with abnormal liver metabolism and diabetes. In addition to fat quantification, fat distribution is also related to diseases. There is clear evidence that excessive deposition of visceral fat leads to a significant increase in the risk of cardiovascular and metabolic diseases in patients. Therefore, the need for non-invasive segmentation and accurate measurement of adipose tissue volume has become increasingly prominent. [0003] There are many methods for measuring the whole body fat volume and local fat volume, such as simple p...
