The lightweight Mamba architecture is introduced into the UNet network, and the SAB and CAB attention mechanisms are introduced on the skip connection. The attention mechanism is used to suppress the irrelevant information in the image and highlight the important local features. The trained network is geometrically evaluated on the test set for segmentation performance, comparison of manual segmentation and predicted skeletal muscle area (SMA). Compare the parameters and computations of SMA-Net with existing networks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The dice similarity coefficient of SMA-Net network for skeletal muscle segmentation was 89.16%, the sensitivity SEN was 88.21%, the positive predictive value PPV was 90.13% and the 95% Hausdorff distance was 5.30mm. Manual segmentation is basically close to the predicted SMA. Our proposed network for cervical cancer patients predicted sarcopenia with 87.5% accuracy, 92.31% precision, 80% recall, 85.72% F1-Score, and 0.871 AUC. The calculation amount of SMA-UNet network is 1.50 GFLOPS, and the parameter amount is 1.24 M. The radiologist\u2019s scores show that minor and no revision accounted for 93.75% on manual revision of skeletal muscle.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The lightweight SMA-Net proposed in this study can accurately segment L3 skeletal muscle and quickly calculate its area, which basically meets the clinical application and is convenient for clinical deployment. It is helpful for clinicians to quickly diagnose sarcopenia in patients with cervical cancer, save medical resources, reduce the workload of physicians, and improve diagnostic efficiency.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15330338261446535","type":"journal-article","created":{"date-parts":[[2026,4,27]],"date-time":"2026-04-27T13:02:51Z","timestamp":1777294971000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["A Lightweight Skeletal Muscle Intelligent Segmentation Network Based on Planning CT for Cervical Cancer Radiotherapy"],"prefix":"10.1177","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9650-4150","authenticated-orcid":false,"given":"Liming","family":"Lu","sequence":"first","affiliation":[{"name":"China Institute of Atomic Energy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiwei","family":"Chen","sequence":"additional","affiliation":[{"name":"Center of Radiation Oncology, The Affiliated Hospital of Hunan Academy of Chinese Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Liu","sequence":"additional","affiliation":[{"name":"Hefei BOE Hospital, Hefei, Anhui, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gongfu","family":"Chen","sequence":"additional","affiliation":[{"name":"Hepatobiliary Ward, Department of General Surgery, Tongling People\u2019s Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junyue","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Foresea Life Insurance Guangzhou General Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5191-0248","authenticated-orcid":false,"given":"Zhe","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Radiology, Neijiang First People\u2019s Hospital,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaokui","family":"He","sequence":"additional","affiliation":[{"name":"China Institute of Atomic Energy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,4,27]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21660"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejca.2025.115375"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.4143\/crt.2017.141"},{"issue":"9","key":"e_1_3_4_5_2","first-page":"5497","article-title":"Association of bowel radiation dose-volume with skeletal muscle loss during pelvic intensity-modulated radiotherapy in cervical cancer","volume":"29","author":"Lee J","year":"2021","unstructured":"Lee J, Lin JB, Wu MH, et al.
