This study aims to investigate the feasibility and safety of a portable microwave breast imaging device in clinical practice. Materials and methods: We retrospectively collected the imaging data of ten breast cancers in nine women (median age: 66.0 years; range: 37\u201378 years) who had undergone microwave imaging examination before surgery. All were Japanese and the tumor sizes were from 4 to 10 cm. Using a five-point scale (1 = very poor; 2 = poor; 3 = fair; 4 = good; and 5 = excellent), a radiologist specialized in breast imaging evaluated the ability of microwave imaging to detect breast cancer and delineate its location and size in comparison with conventional mammography and the pathological findings. Results: Microwave imaging detected 10\/10 pathologically proven breast cancers, including non-invasive ductal carcinoma in situ (DCIS) and micro-invasive carcinoma, whereas mammography failed to detect 2\/10 breast cancers due to dense breast tissue. In the five-point evaluation, median score of location and size were 4.5 and 4.0, respectively. Conclusion: The results of the evaluation suggest that the microwave imaging device is a safe examination that can be used repeatedly and has the potential to be useful in detecting breast cancer.<\/jats:p>","DOI":"10.3390\/diagnostics12010027","type":"journal-article","created":{"date-parts":[[2021,12,23]],"date-time":"2021-12-23T10:16:18Z","timestamp":1640254578000},"page":"27","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Feasibility of Portable Microwave Imaging Device for Breast Cancer Detection"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9359-0972","authenticated-orcid":false,"given":"Mio","family":"Adachi","sequence":"first","affiliation":[{"name":"Department of Surgery, Breast Surgery, Tokyo Medical and Dental University, Tokyo 113-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1967-0445","authenticated-orcid":false,"given":"Tsuyoshi","family":"Nakagawa","sequence":"additional","affiliation":[{"name":"Department of Surgery, Breast Surgery, Tokyo Medical and Dental University, Tokyo 113-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7141-8901","authenticated-orcid":false,"given":"Tomoyuki","family":"Fujioka","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Tokyo Medical and Dental University, Tokyo 113-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6107-4519","authenticated-orcid":false,"given":"Mio","family":"Mori","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Tokyo Medical and Dental University, Tokyo 113-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazunori","family":"Kubota","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Tokyo Medical and Dental University, Tokyo 113-8510, Japan"},{"name":"Department of Radiology, Dokkyo Medical University, Tochigi 321-0293, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Goshi","family":"Oda","sequence":"additional","affiliation":[{"name":"Department of Surgery, Breast Surgery, Tokyo Medical and Dental University, Tokyo 113-8510, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takamaro","family":"Kikkawa","sequence":"additional","affiliation":[{"name":"Research Institute for Nanodevice and Bio Systems, Hiroshima University, Hiroshima 739-8527, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"438","DOI":"10.3322\/caac.21583","article-title":"Breast cancer statistics, 2019","volume":"69","author":"DeSantis","year":"2019","journal-title":"CA Cancer J.
