即使有放射线照片，腺瘤样牙源性肿瘤在术前也常常无法诊断。本研究评估放射学结果，特别强调腺瘤样牙源性肿瘤的特征性射线不透性。在将放射学结果与病理结果相关联时，发现口内根尖周X线片和全景X线片之间的诊断准确性存在差异。口内根尖周X线照片允许将腺瘤样牙源性肿瘤中的射线不透性感知为离散病灶，即使具有最小的钙化沉积物，在放射通透性内具有絮状模式。当钙化很小时，全景放射线摄影通常无法证明腺瘤样牙源性肿瘤的射线不透性。结果表明，在存在微量钙化沉积物的情况下，口内X光片对于正确诊断腺瘤样牙源性肿瘤可能至关重要。
Adenomatoid odontogenic tumor is frequently not diagnosed preoperatively even when radiographs are available. This study evaluates radiographic findings with special emphasis on the characteristic radiopacities of adenomatoid odontogenic tumor. In correlating radiologic findings with pathologic findings, differences in diagnostic accuracy between intraoral periapical and panoramic radiographs were found. The intraoral periapical radiograph allows perception of the radiopacities in adenomatoid odontogenic tumor as discrete foci having a flocculent pattern within radioulcency even with minimal calcified deposits. Panoramic radiography was often unable to demonstrate radiopacities in adenomatoid odontogenic tumor when the calcification was minimal. The result indicates that intraoral radiographs may be essential for correct radiographic interpretation of an adenomatoid odontogenic tumor in the presence of minimal quantities of calcified deposits.
