Pain assessment system based on magnetic resonance resting-state functional imaging

Abstract

The invention discloses a pain evaluation system based on magnetic resonance resting state functional imaging, and the pain evaluation system comprises a pain characteristic specimen library for storing history resting state functional imaging attributes of specimens of patients with different pain levels and pain causes and control normal persons; a functional imaging unit for obtaining resting state functional imaging data from brains of new individual patients suffering from chronic pain and transmitting to an attribute extraction unit; the attribute extraction unit for extracting resting state functional image attributes of new individuals from the resting state functional imaging data; and a pain evaluation unit for comparing the resting state functional image attributes of new individuals and the history resting state functional image attributes in the pain characteristic specimen library, and evaluating pain levels and / or pain causes of new individuals. Hereby, the pain evaluation system disclosed by the invention can objectively and accurately evaluate pain levels and / or pain causes through objective image data of human brains.

Description

technical field [0001] The invention relates to an imaging system for assessing pain levels and / or pain causes of chronic pain patients based on magnetic resonance resting state functional imaging data. Background technique [0002] Pain is one of the most common human sufferings and one of the most unbearable symptoms for patients. The International Association for the Study of Pain (IASP) defines pain as "the unpleasant and emotional experience of actual or potential tissue damage or similar conditions". This definition emphasizes that pain is not only a sensory phenomenon, but also a multidimensional phenomenon, including sensory, affective, motivational, environmental and cognitive components. The IASP defines chronic pain as "pain that exceeds normal tissue healing time (typically 3 months)". [0003] Chronic pain not only brings pain to individuals, but also causes a serious economic burden to the whole society due to the high incidence rate of chronic pain in the po...

Problems solved by technology

[0008] However, the existing subjective assessment methods for assessing pain are easily affected by many external factors, thereby affecting the objectivity and accuracy of the assessment. The existing objective assessment methods only rely on a single index to judge and cannot accurately and objectively reflect the pain level. There are assessment methods that focus primarily on pain perception and do not distinguish between causes of pain

In summary, the existing pain assessment technology obviously has inconvenience and defects in actual use, so it is necessary to improve it
