Purpose
The aim of this study was to investigate the gallium-67 (67Ga) single-photon emission-computed tomography (SPECT-CT) for the evaluation of head and neck, especially maximum standardised uptake value (SUVmax) in lesions, and in the parotid and submandibular glands.

Material and methods
Fourteen patients with head and neck lesions who underwent SPECT-CT at 72 hours after injection of 67Ga were included in this study. The 67Ga SPECT-CT parameters SUVmax were compared between the parotid glands and submandibular glands. Statistical analyses for the SUVmax were performed by Mann-Whitney U test. A p value lower than 0.05 was considered as statistically significant.

Results
Of all 14 patients, 67Ga SPECT-CT was positive for two cases (one malignant lymphoma and one osteomye­litis). The SUVmax for malignant lymphoma and osteomyelitis were 11.21 and 10.95, respectively. Furthermore, SUVmax for parotid glands and submandibular glands of all patients were 4.86 ± 1.89 and 4.64 ± 1.64, respectively (p = 0.694).

Conclusions
This study investigated the 67Ga SPECT-CT for the evaluation of head and neck, especially SUVmax of lesions, and the parotid and submandibular glands. 67Ga SPECT-CT may be an effective technique for the evaluation of maxillofacial lesions.
