This study uses PET imaging to observe the uptake and metabolism of 18F-fluorodeoxyglucose (18F-FDG) in the multibrain areas of the emotional control loop in patients with generalized anxiety disorder (GAD) and investigate the brain of GAD patient\u2019s functional abnormality mechanism. Methods. The thesis clinically collected 20 GAD patients and 20 healthy subjects. Dynamic PET-CT scans were used. At the same time, 18F-FDG whole-brain uptake and metabolism data were collected. Image fusion and semiquantitative analysis were used to measure emotional control loops. The maximum standard uptake value (SUVmax) and dynamic uptake and metabolic changes of 11 time points in the brain area at 150\u2009min were measured. Results. Compared with the healthy control group, the peak uptake of the bilateral prefrontal cortex and the average uptake rate before the peak in GAD patients were significantly reduced (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.05<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>), and the average metabolic rate after the peak was significantly increased (<jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                        <c:mo>&lt;<\/c:mo>\n                        <c:mn>0.05<\/c:mn>\n                     <\/c:math>\n                  <\/jats:inline-formula>).

Conclusion. There are 18F-FDG uptake and metabolic disorders in multiple brain areas of the affective control loop of GAD patients. The abnormal peak and rate of uptake may be related to the pathogenesis of GAD.<\/jats:p>","DOI":"10.1155\/2021\/4505227","type":"journal-article","created":{"date-parts":[[2021,7,22]],"date-time":"2021-07-22T21:05:08Z","timestamp":1626987908000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Application of PET Imaging in the Brain Regions of the Emotional Control Loop in Patients with Generalized Anxiety Disorder"],"prefix":"10.1155","volume":"2021","author":[{"given":"Jing","family":"Li","sequence":"first","affiliation":[{"name":"Hubei Provincial Hospital of Traditional Chinese Medicine, Wuhan 430000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5912-6511","authenticated-orcid":true,"given":"Wenjun","family":"Ouyang","sequence":"additional","affiliation":[{"name":"School of Economics and Management, China University of Geosciences (Wuhan), Wuhan 430000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1038\/171737a0"},{"issue":"3","key":"2","first-page":"191","article-title":"Effects of passion flower extract, as an add-on treatment to sertraline, on reaction time in patients with generalized anxiety disorder: a double-blind placebo-controlled study","volume":"11","author":"M.
