X线数字化断层融合成像与MSCT在颌骨牙源性囊性病变诊断中的评估对比
Comparison of assessments with digital tomosynthesis and MSCT in diagnosis of odontogenic cystic lesions of the jaws
摘要
Abstract
Objective To evaluate the value of digital tomosynthesis (TOMOS)in diagnosis of odontogenic cystic lesions of the jaws with oral fixed metal dentures, and compared with multi-slice spiral CT (MSCT). Methods The imaging findings of 40 cases with fixed metal dentures pathologically proved odontogenic cystic lesions of the jaws jn retrospective were retrospectively analyzed.All cases were performed by MSCT and TOMOS scanning,and 13 cases enhanced at the same time. The characteristics of the imaging findings in TOMOS and MSCT were compared. The diagnosis merits and disadvantages, especially their ability to detect the lesions and adjacent structures,were assessed. Results There were no significant difference (consistency check Kappa value>0.4) in evaluating the structure characteristics of the lesions, the relationgship between the lesions and cortex ,and the relationship between the lesions and surrounding organs. TOMOS is superior to MSCT in displaying apical change, the same in pure cystic and cystic-solid lesions interfered by artifacts.However, it is inferior to MSCT in detection of soft tissue invasion. Conclusion There is similar assessment value of TOMOS and MSCT in displaying odontogenic cystic lesions of the jaws. TOMOS can be chosen when the imaging findings of the lesions are interfered by metal artifacts.关键词
