The WBBS has shown high sensitivity but relatively low specificity due to bone variation. This study aims to use the self-developing irregular flux viewer (IFV) system to predict possible bone lesions in planar WBBS. The study uses gradient vector flow (GVF) and self-organizing map (SOM) methods to analyze the blood fluid-dynamics and evaluate hot points. The evaluation includes a selection of 368 patients with bone metastasis from prostate cancer, lung cancer and breast cancer. Finally, we compare IFV values with BONENAVI version data. BONENAVI is a computer-assisted diagnosis system that analyzes bone scintigraphy automatically. The analysis shows that the IFV system achieves sensitivities of 93% for prostate cancer, 91% for breast cancer, and 83% for lung cancer, respectively. On the other hand, our proposed approach achieves a higher sensitivity than the results of BONEVAVI version 2.0.5 for prostate cancer (88%), breast cancer (86%) and lung cancer (82%), respectively. The study results demonstrate that the high sensitivity and specificity of the IFV system can provide assistance for image interpretation and generate prediction values for WBBS.<\/jats:p>","DOI":"10.3233\/xst-200834","type":"journal-article","created":{"date-parts":[[2021,5,5]],"date-time":"2021-05-05T05:49:03Z","timestamp":1620193743000},"page":"617-633","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparison of irregular flux viewer system with BONENAVI version for identification of Tc-99m MDP whole body bone scan metastasis images"],"prefix":"10.1177","volume":"29","author":[{"given":"Chang-Ching","family":"Yu","sequence":"first","affiliation":[{"name":"Department of Nuclear Medicine, Kaohsiung Veterans General Hospital, Kaohsiung, Taiwan"},{"name":"Department of Medical Imaging and Radiology, Shu-Zen Junior College of Medicine and Management, Kaohsiung, Taiwan"},{"name":"Department of Chemistry, R.O.C Military Academy, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chien-Yi","family":"Ting","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging and Radiology, Shu-Zen Junior College of Medicine and Management, Kaohsiung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming-Hui","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Medical Education and Research, Kaohsiung Veterans General Hospital, Kaohsiung, Taiwan"},{"name":"Center of General Education, Shu-Zen Junior College of Medicine and Management, Kaohsiung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hung-Pin","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Kaohsiung Veterans General Hospital, Kaohsiung, Taiwan"},{"name":"Department of Medical Imaging and Radiology, Shu-Zen Junior College of Medicine and Management, Kaohsiung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,4,30]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21492"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4471-1407-9_5"},{"key":"ref003","first-page":"493","volume":"12","author":"Sergieva S.","year":"2007","journal-title":"Off J Balk Union Oncol"},{"key":"ref004","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000123981.03084.06"},{"key":"ref005","doi-asserted-by":"publisher","DOI":"10.1007\/s00259-004-1541-x"},{"issue":"10","key":"ref006","first-page":"1439","volume":"164","author":"Myers R.E.","year":"2001","journal-title":"CMAJ"},{"key":"ref007","doi-asserted-by":"publisher","DOI":"10.3810\/pgm.1998.11.401"},{"key":"ref008","first-page":"21","volume":"35","author":"M\u00fcller V.","year":"2001","journal-title":"Radiol Oncol"},{"key":"ref009","doi-asserted-by":"publisher","DOI":"10.1007\/s12149-014-0921-y"},{"key":"ref010","doi-asserted-by":"publisher","DOI":"10.1109\/TNS.2007.897830"},{"key":"ref011","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/957364"},{"key":"ref012","unstructured":"SahaG.B., Fundamentals of Nuclear Pharmacy;
