fa Contrast-enhanced multidetector computerized tomography for odontogenic cysts and cystic-appearing tumors of the jaws: is it useful? رادیولوژی دهان، فک و صورت Oral and Maxillofacial Radiology پژوهشي Research <p> <strong>Objective</strong></p><p>  The purpose of this study was to investigate the usefulness of computerized tomography (CT), particularly contrast-enhanced CT, in differentiation of jaw cysts and cystic-appearing tumors. </p><p> <strong>Study Design</strong></p><p>  We retrospectively analyzed contrast-enhanced CT images of 90 patients with odontogenic jaw cysts or cystic-appearing tumors. The lesion size and CT values were measured and the short axis to long axis (S/L) ratio, contrast enhancement (CE) ratio, and standard deviation ratio were calculated. </p><p> <strong>Results</strong></p><p> <strong> </strong>The lesion size and the S/L ratio of keratocystic odontogenic tumors were significantly different from those of radicular cysts and follicular cysts. There were no significant differences in the CE ratio among the lesions. </p><p> <strong>Conclusions</strong></p><p>  Multidetector CT provided diagnostic information about the size of odontogenic cysts and cystic-appearing tumors of the jaws that was related to the lesion type, but showed no relation between CE ratio and the type of these lesions. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(12)01622-7/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1508&slc_lang=fa&sid=1 Naoya Kakimoto 10031947532846006885 10031947532846006885 Yes Department of Oral and Maxillofacial Radiology, Osaka University Graduate School of Dentistry, Osaka, Japan Jira Chindasombatjareon 10031947532846006886 10031947532846006886 No Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Mahidol University, Bangkok, Thailand Seiki Tomita 10031947532846006887 10031947532846006887 No Department of Oral and Maxillofacial Radiology, Osaka University Graduate School of Dentistry, Osaka, Japan Hiraoki Shimamoto 10031947532846006888 10031947532846006888 No Department of Oral and Maxillofacial Radiology, Osaka University Graduate School of Dentistry, Osaka, Japan Yuka Uchiyama 10031947532846006889 10031947532846006889 No Department of Oral and Maxillofacial Radiology, Osaka University Graduate School of Dentistry, Osaka, Japan Yoko Hasegawa 10031947532846006890 10031947532846006890 No Department of Dentistry and Oral Surgery, Hyogo College of Medicine, Hyogo, Japan Mitsunobu Kishino 10031947532846006891 10031947532846006891 No Department of Oral Pathology, Osaka University Graduate School of Dentistry, Osaka, Japan Shumei Murakami 10031947532846006892 10031947532846006892 No Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Mahidol University, Bangkok, Thailand Souhei Furukawa 10031947532846006893 10031947532846006893 No Department of Oral and Maxillofacial Radiology, Osaka University Graduate School of Dentistry, Osaka, Japan
