Introduction:The quantitative parameter was successfully derived from the quantitative bone SPECT/CT images. The aim of this study was to evaluate maximum standardized uptake value (SUV) of normal structures in the head and neck with bone SPECT/CT. Methods: Fifty-three patients with jaw lesions (11 chronic osteomyelitis, eight osteoradionecrosis and 34 medication-related osteonecrosis of the jaw) who had bone SPECT/CT were prospectively included. The maximum SUV of normal structures including vertebrae, sternal body, parietal bone and hyoid bone were analysed. Statistical analyses for the maximum SUV were performed by Pearson's rank correlation test. A P value lower than 0.05 was considered statistically significant. Results: The maximum SUVs of vertebrae, sternal body, parietal bone and hyoid bone of all patients were 8.10 AE 3.72, 5.16 AE 2.05, 3.67 AE 1.55 and 1.44 AE 0.56, respectively. Furthermore, the maximum SUV of vertebrae was significantly correlated with that of sternal body (Y = 0.527X + 5.388 (R 2 = 0.084, P = 0.035)). Conclusions: Maximum SUV with bone SPECT/CT should be useful for characterization of normal structures in the head and neck. Furthermore, the data reported herein can be used for reference in future studies and in clinical settings for head and neck lesions.

Objectives: To investigate the assessment of inflammatory jaw pathologies using bone single-photon emission CT-CT (SPECT/CT) maximum standardized uptake value (SUVmax). Methods: 44 patients with inflammatory jaw pathologies (7 chronic osteomyelitis, 8 osteoradionecrosis and 29 medication-related osteonecrosis of the jaw (MRONJ)) underwent SPECT/CT at 4 h after injection of 99mTc hydroxymethylene diphosphonate. The SPECT/CT parameters SUVmax of the inflammatory jaw pathologies were analyzed. Statistical analyses for the SUVmax were performed by one-way repeated measures analysis of variance with Tukey's honestly significant difference test. A p-value lower than 0.05 was considered statistically significant. Results: The mean and standard deviation of SUVmax for 7 chronic osteomyelitis, 8 osteoradionecrosis and 29 MRONJ were 24.94 ± 3.65, 12.27 ± 5.47 and 16.55 ± 9.12, respectively. The SUVmax for chronic osteomyelitis were significantly higher than those for osteoradionecrosis (p = 0.011) and MRONJ (p = 0.043). Conclusions: Bone SPECT/CT SUVmax in the uptake of 99mTc hydroxymethylene diphosphonate reflecting bone physiological changes for chronic osteomyelitis were significantly higher than those of osteonecrosis, such as osteoradionecrosis and MRONJ. Bone SPECT/CT SUVmax should be useful for the assessment of inflammatory jaw pathologies, such as chronic osteomyelitis, osteoradionecrosis and MRONJ.

Involvement of the submandibular gland in actinomycotic osteomyelitis in the absence of sinus is rare. Cervicofacial form is characterized by contiguous spread, suppurative osteomyelitic & granulomatous inflammation of the mandible and formation of multiple abscesses and hallmark discharging sinuses draining serosanguinous fluid containing sulphur granules. As the imaging finding of this entity is rarely described, in this case report, a rare case of mandibular actinomycotic osteomyelitis, with a submandibular swelling, but without draining sinus is reported. The imaging findings of cone beam computed tomography (CBCT) & ultrasonography (US) of the case are discussed with a review. In subacute stage, mandibular actinomycosis may show no hallmark sinuses. Sclerotic margins around the lesion may be found on radiograph. Imaging is useful in ruling out clinical diagnostic challenge when it includes involvement of mandible & submandibular region. Cervicofacial actinomycosis commonly occurs as perimandibular infection, rarely as osteomyelitis of the mandible.1 It may present as two distinct morphological patterns; first, "lumpy jaw," and second, simulating an acute pyogenic infection affecting the submandibular area, discharging sinus being a hallmark finding.1 Other variant reported include chronic osteitis, osteolytic lesion, hard nodule on the tongue, lockjaw, periapical, or paradental abscess. Diagnosis of cases presenting in multiple areas in the absence of multiple discharging sinuses is a challenge.2 Usefulness the imaging findings are rarely enumerated. This report is of a twin presentation of a non - sinus forming actinomycotic mandibular osteomyelitis and a submandibular swelling, along with a review of various diagnostic imaging features.
