Problems solved by technology

On the other hand, the proximal interphalangeal joints (PIPJs) are the earliest and most commonly involved joints in RA, which are included in both X-ray and ultrasound evaluations, but the existing MRI evaluations of RA only include the wrist and metacarpophalangeal joints, mainly The reason is limited by MRI equipment and scan time
Therefore, there is currently a lack of MRI assessment criteria for PIPJs, and PIPJs are not included in RAMRIS

Embodiment 1

[0045] The present embodiment provides a system for analyzing rheumatoid arthritis, which includes:

[0046] Patient data acquisition module, the patient data reading module includes a nuclear magnetic resonance instrument, used to acquire image information of synovitis, osteitis, tenosynovitis, bone erosion, and narrow joint space of the proximal interphalangeal joints of both hands of the patient;

[0047] The data input module is used to read the image information in the patient data acquisition module, and give the scores of synovitis, osteitis, tenosynovitis, bone erosion, and joint space narrowing according to the scoring standard;

[0048] The analysis module uses a regression model to calculate the total score, and evaluates the development status of rheumatoid arthritis according to the total score.

[0049] Preferably, the patient is examined by the following method: the patient takes a prone position, raises both hands above the head, puts them flat in the center of...

Abstract

The invention provides a system for analyzing rheumatoid arthritis (RA). The system according to the invention comprises a patient data acquisition module, a data input module and an analysis module,thereby understanding a joint destruction progress of an RA patient and monitoring the treatment effect of diseases in time. According to the system of the invention, a nuclear magnetic resonator utilizes a 3.0T whole-body scanning system realizes higher image resolution through increasing a signal-to-noise ratio by means of an eight-channel head coil. The average scanning time is only 24 minutes,thereby laying a solid basis for later clinical popularization.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a system for analyzing rheumatoid arthritis. Background technique [0002] Rheumatoid arthritis (RA) is a disabling chronic autoimmune disease characterized by joint inflammation and destruction, and is one of the most common inflammatory joint diseases. Imaging examination is an important part of RA joint evaluation, including X-ray, computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound. In the routine clinical diagnosis, management and clinical trials of RA, the narrow joint space and bone erosion of the hands, wrists, and feet are used in X-ray evaluation as indicators of joint structural damage. The typical X-ray manifestations of RA are the 1987 American Rheumatology Association (ACR) Components of the RA classification diagnostic criteria. However, in early RA patients, only a small number of patients can see bone erosion on X-ray exam...
