Ninety patients with ileus were recruited, and the patients were treated with CD and underwent MRI scans of the lower abdomen. A BPNN model was fabricated and applied to segment the MRI images of patients and identify the lesion. As a result, when the overlap step was 16 and the block size was 32\u2009\u00d7\u200932, the running time of the BPNN algorithm was the shortest. The segmentation accuracy was the highest if there were two hidden layer (HL) nodes, reaching 97.3%. The recognition rates of small intestinal stromal tumor (SIST), colon cancer, adhesive ileus, and volvulus of MRI images segmented by the algorithm were 91.5%, 88.33%, 90.3%, and 88.9%, respectively, which were greatly superior to those of manual interpretation (<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>). After the intervention of CD, the percentages of patients with ileus that were cured, markedly effective, effective, and ineffective were 65.38%, 23.16%, 5.38%, and 6.08%, respectively. The cure rate after intervention of CD (65.38%) was much higher in contrast to that before intervention (13.25%) (<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>). In short, CD showed a good therapeutic effect on ileus and can effectively improve the prognosis of patients. In addition, MRI images based on BPNN showed a good diagnostic effect on ileus, and it was worth applying to clinical diagnosis.<\/jats:p>","DOI":"10.1155\/2021\/1667024","type":"journal-article","created":{"date-parts":[[2021,12,24]],"date-time":"2021-12-24T21:35:11Z","timestamp":1640381711000},"page":"1-8","source":"Crossref","is-referenced-by-count":2,"title":["Back Propagation Neural Network-Based Magnetic Resonance Imaging Image Features in Treating Intestinal Obstruction in Digestive Tract Diseases with Chengqi Decoction"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3787-7773","authenticated-orcid":true,"given":"Yongfeng","family":"Li","sequence":"first","affiliation":[{"name":"Department of Emergency Medical, Xianyang Central Hospital, Xianyang 712000, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6905-5745","authenticated-orcid":true,"given":"Kaina","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Encephalopathy, Xi\u2019an Hospital of Traditional Chinese Medicine, Xi\u2019an 710000, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7597-4203","authenticated-orcid":true,"given":"Li","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Pain, Xianyang Central Hospital, Xianyang 712000, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5261-9900","authenticated-orcid":true,"given":"Xiaojun","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Geriatrics, Xianyang Central Hospital, Xianyang 712000, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2019.09.007"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000002159"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0000000000000602"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/1421753"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1007\/s11604-020-01053-w"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1002\/pd.5296"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2015.06.009"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-019-06441-z"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.31557\/APJCP.2018.19.11.3257"},{"issue":"4","key":"10","first-page":"419","article-title":"[Effect of modified dachengqi decoction on recovery of gastrointestinal function after surgery in patients with rectal cancer]","volume":"37","author":"J.
