Abstract

Objectives

To evaluate and compare the diagnostic potential of 18F-fluorodeoxyglucose positron emission tomography/magnetic resonance imaging (18FDG-PET/MRI) and MRI for recurrence diagnostics after primary therapy in patients with adenoid cystic carcinoma (ACC).

Methods

A total of 32 dedicated head and neck 18F-FDG PET/MRI datasets were included in this analysis. MRI and 18F-FDG PET/MRI datasets were analyzed in separate sessions by two readers for tumor recurrence or metastases.

Results

Lesion-based sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were 96%, 84%, 90%, 93%, and 91% for 18F-FDG PET/MRI and 77%, 94%, 95%, 73%, and 84% for MRI, resulting in a significantly higher diagnostic accuracy of 18F-FDG PET/MRI compared to MRI (P < .005).

Conclusion

18F-FDG PET/MRI is superior to MRI in detecting local recurrence and metastases in patients with ACC of the head and neck. Especially concerning its negative predictive value, 18F-FDG PET/MRI outperforms MRI.
