Objective: To evaluate the usefulness of [(18)F]fluoromisonidazole ([(18)F]FMISO)-positron emission tomography (PET) prior to the treatment of head and neck squamous cell carcinoma.

Methods: Seventeen patients with untreated HNSCC underwent pretreatment [(18)F]FMISO PET. Six of them underwent definitive surgery and the remaining 11 definitive (chemo-)radiotherapy.

Objectives: We evaluated differential diagnoses of cystic parotid gland lesions and the efficacy of preoperative diagnosis.

Materials And Methods: Of 191 parotid gland nodules resected between January 2003 and October 2008, 167 (87%) were benign and 24 (13%) malignant. Thirty-five parotid gland nodules whose components were almost cystic were enrolled in this study.

Purpose: To evaluate whether 2-deoxy-2-[(18)F]fluoro-D-glucose positron emission tomography/computed tomography (FDG-PET/CT) more accurately predicts the histopathologic response to neoadjuvant chemotherapy (NAC) than magnetic resonance imaging (MRI) in patients with head and neck squamous cell carcinoma (HNSCC).

Procedures: Sixteen patients with HNSCC underwent FDG-PET/CT and MRI scans before and after one cycle of NAC, followed by surgical resection. The 26 surgically resected specimens of the 16 patients were analyzed.

Conclusion: Activation of cortical areas related to visual motion processing and control of eye movement, and deactivation of parieto-insular vestibular cortices (PIVC) were revealed by functional magnetic resonance imaging (fMRI) with small-field optokinetic stimulation (OKS). The results agreed well with those of previous studies, which indicates that the current protocol is reliable enough to be used as a clinical examination.

Objectives: To propose an fMRI set-up with OKS that is reliable and simple enough to be performed as a clinical test.

Conclusion: The use of fluorodeoxyglucose positron emission tomography (FDG-PET) with a visual language task provided objective information on the development and plasticity of cortical language networks. This approach could help individuals involved in the habilitation and education of prelingually deafened children to decide upon the appropriate mode of communication.

Objectives: To investigate the cortical processing of the visual component of language and the effect of deafness upon this activity.
