DWI was performed on a 1.5 T unit, with b factor of 0 and 800 s\/mm<sup>2<\/sup>; moreover, ADC maps were generated. ADC values were measured for normal structures, odontogenic infections, squamous cell carcinomas (SCC), and hemangiomas. <br \/>\n<b>Results<\/b>: As regards the normal structures, the mean ADC value of the cerebrospinal fluid (3.65\u00b10.60\u00d710<sup>\u20133<\/sup> mm<sup>2<\/sup>\/s) in the upper neck area was higher than that of the spinal cord (0.74\u00b10.15\u00d710<sup>\u20133<\/sup> mm<sup>2<\/sup>\/s, P=0.000), lymph nodes (0.87\u00b10.17\u00d710<sup>\u20133<\/sup> mm<sup>2<\/sup>\/s, P=0.000), and Waldeyer\u2019s ring (0.92\u00b10.29\u00d710<sup>\u20133<\/sup> mm<sup>2<\/sup>\/s, P=0.000). The mean ADC value of hemangiomas (1.52\u00b10.31\u00d710<sup>\u20133<\/sup> mm<sup>2<\/sup>\/s) was higher than that of odontogenic infections (0.85\u00b10.36\u00d710<sup>\u20133<\/sup> mm<sup>2<\/sup>\/s, P=0.034) and SCC (1.38\u00b10.22\u00d710<sup>\u20133<\/sup> mm<sup>2<\/sup>\/s, P=0.840). Furthermore, MIP (DWI) showed the normal structures and lesions in the oral and maxillofacial region in an improved way. <br \/>\n<b>Conclusions<\/b>: DWI, ADC maps, and MIP can be used to characterize and differentiate normal structures and lesions in the oral and maxillofacial region.<\/jats:p>","DOI":"10.12659\/pjr.902524","type":"journal-article","created":{"date-parts":[[2018,3,6]],"date-time":"2018-03-06T16:51:11Z","timestamp":1520355071000},"page":"571-577","source":"Crossref","is-referenced-by-count":16,"title":["Diffusion-Weighted Imaging in the Oral and Maxillofacial Region: Usefulness of Apparent Diffusion Coefficient Maps and Maximum Intensity Projection for Characterization of Normal Structures and Lesions"],"prefix":"10.5114","volume":"82","author":[{"given":"Ichiro","family":"Ogura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihiko","family":"Sasaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayako","family":"Kameta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikiko","family":"Sue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takaaki","family":"Oda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3061","published-online":{"date-parts":[[2018,2,2]]},"container-title":["Polish Journal of Radiology"],"original-title":[],"link":[{"URL":"https:\/\/www.polradiol.com\/pdf-187502-108611","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.polradiol.com\/pdf-187502-108611","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,22]],"date-time":"2024-05-22T11:32:52Z","timestamp":1716377572000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.polradiol.com\/Diffusion-Weighted-Imaging-in-the-Oral-and-Maxillofacial-Region-Usefulness-of-Apparent,187502,0,2.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,2,2]]},"references-count":0,"alternative-id":["187502"],"URL":"https:\/\/doi.org\/10.12659\/pjr.902524","relation":{},"ISSN":["1899-0967"],"issn-type":[{"value":"1899-0967","type":"print"}],"subject":[],"published":{"date-parts":[[2018,2,2]]}}}
