Roentgen and X-ray computerized tomographic (CT) imaging of cysts in the maxilla

Abstract

Two cysts in the maxilla were subjected to routine roentgen imaging followed by CT scanning. Roentgen investigation included periapical, occlusal, and panoramic views. CT imaging included axial and coronal scans. While roentgen views were adequate in establishing the diag­ nosis of the cystic lesions, CT scan was useful in understanding the precise antero-posterior expansion and depth of the lesion. Interpretation of CT scan of cystic jaw lesions without con­ ventional radiographs can be misleading. Hence, the CT procedure may be used only as sup­ plement to the routine radiographic investigations particularly in cystic lesions of the jaws
