The validity of SPECT/CT in diagnosis of condylar hyperplasia

Abstract

Purpose: To study the diagnostic validity of hybrid single photon emission computed tomography (SPECT) integrated with multidetector computed tomography (SPECT/CT) in diagnosis of condylar hyperplasia (CH). Subjects and methods: 20 patients with suspected CH underwent SPECT/CT were studied during the period from August 2015 to January 2017. Results: Increased bone activity was noted in the affected condyles for all CH patients. The relative percentage uptake on the affected side was significantly higher than the uptake on the contralateral side (56.9 ± 5.35 vs 43 ± 2.6%, P 1.11 and <1.4 respectively, giving a 100% sensitivity and 100% specificity for detecting the hyperactivity in mandibular condyle. Conclusion: SPECT/CT had a high diagnostic validity in assessment of CH and can provide a reference for treatment options
