Abstract : Early diagnosis and complete resection of a tumor mass are the most important factors that improve prognosis and prevent recurrence. Single Photon Emission Computed Tomography (SPECT) is a recently developed technique for gathering and displaying nuclear medicine images. Ten patients were suffering from tumor recurrence were studied using panoramic radiography and SPECT. Rcsults of this study revealed that lesion type, border definition, alveolar bone loss and teeth relation of recurrent benign and malignant tumors were clearly identified on panoramic radiographs with statistical significancedifference(P less than O.OOOI) comparedto SPECTfindings.Soft tissue involvement, vascularity, bone uptake and abnormal ratio were clearly identified on SPECT scan with statistical significance difference(P less than O.OOOI)compared to panoramic radiographs. There was no statistical significance difference regarding bone affection, only one case was identified on SPECT scan and not on panoramic radiograph. We can conclude that SPECT complement rather than replace radiography, Periodic long-term radionuclide scanning should be recommended for all asymptomatic patients given the risk of rcsidual and/or reactivating tumoral tissue with benign or malignant behavior, lastly, the size of the lesion on SPECT scan is exaggerated than the size on panoramic radiographs due to bone scanning gives the actual bone involvcment which is very important in lesions of high recurrence for determination of the suitablc safcty margins to prevent recurrence.
