fa Variety and complexity of fluorine-18-labelled fluoro-2-deoxy-D-glucose accumulations in the oral cavity of patients with oral cancers رادیولوژی دهان، فک و صورت Oral and Maxillofacial Radiology پژوهشي Research <p> <strong>Objectives:</strong> To elucidate the points that require attention when interpreting fluorine-18-labelled fluoro-2-deoxy-D-glucose (18F-FDG)/positron emission tomography (PET) images by demonstration of 18F-FDG accumulation in various areas of the oral cavity other than primary lesions in patients with oral cancers. </p><p> <strong>Methods:</strong> 18F-FDG accumulations with a maximal standardized uptake value of over 2.5 in various areas of the oral cavity other than primary lesions were identified in 82 patients with oral cancers.</p><p> <strong> Results:</strong> 18F-FDG/PET-positive areas, excluding primary tumours, included the front intrinsic muscles of the tongue (89.0%), upper and lower marginal parts of the orbicularis oris muscle (64.6%), sublingual glands, palatine tonsil, pharyngeal tonsil, and lingual tonsil. In addition, some areas in the jaws also showed accumulation. </p><p> <strong>Conclusions:</strong> In patients with oral cancers, areas of 18F-FDG accumulation in the oral cavity should be precisely identified and appropriately diagnosed, because accumulations can be seen in areas other than the primary tumour. </p><hr><p></p><p> <strong>Source: </strong>DentoMaxilloFacial Radiology </p><p> <a href="http://dmfr.birjournals.org/content/42/7/20130014.abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> fluorine-18-labelled fluoro-2-deoxy-D-glucose, positron emission tomography computerized tomography ,tongue ,oral cancer ,oral cavity, mimetic muscles 0 0 http://idai.ir/browse.php?a_code=A-10-32-1414&slc_lang=fa&sid=1 S Kito 10031947532846006490 10031947532846006490 No Division of Diagnostic Radiology, Kyushu Dental University, Kitakyushu, Japan H Koga 10031947532846006491 10031947532846006491 No Kitakyushu PET Center, Nishinippon Sangyoeiseikai, Kitakyushu, Japan M Kodama 10031947532846006492 10031947532846006492 No Division of Oral and Maxillofacial Surgery, Kyushu Dental University, Kitakyushu, Japan M Habu 10031947532846006493 10031947532846006493 No Division of Oral and Maxillofacial Surgery, Kyushu Dental University, Kitakyushu, Japan S Kokuryo 10031947532846006494 10031947532846006494 No Division of Oral and Maxillofacial Surgery, Kyushu Dental University, Kitakyushu, Japan N Yamamoto 10031947532846006495 10031947532846006495 No Department of Oral and Maxillofacial Surgery, Oita University, Oita, Japan M Oda 10031947532846006496 10031947532846006496 No Division of Diagnostic Radiology, Kyushu Dental University, Kitakyushu, Japan T Nishino 10031947532846006497 10031947532846006497 No Division of Pulp Biology, Operative Dentistry and Endodontics, Kyushu Dental University, Kitakyushu, Japan M Zhang 10031947532846006498 10031947532846006498 No Division of Oral Pathology, Kyushu Dental University, Kitakyushu, Japan Y Morimoto rad-mori@kyu-dent.ac.jp 10031947532846006499 10031947532846006499 Yes Division of Diagnostic Radiology, Kyushu Dental University, Kitakyushu, Japan/Center for Oral Biological Research, Kyushu Dental University, Kitakyushu, Japan
